Nginx作为一款优秀的Web Server软件同时也是一款优秀的负载均衡或前端反向代理、缓存服务软件
2.编译安装Nginx
（1）安装Nginx依赖函数库pcre
pcre为“perl兼容正则表达式”perl compatible regular expresssions,安装其是为了使Nginx支持具备URI重写功能的rewrite模块，如果不安装Nginx将无法使用rewrite模块功能，但是该功能却十分有用和常用。
检查系统中是否有安装：
[root@leaf ~]# rpm -q pcre pcre-devel
上面可以看到并没有安装使用yum方式安装如下：
[root@leaf ~]# yum install pcre pcre-devel -y
......
Installed:
pcre-devel.x86_64 0:7.8-7.el6
Updated:
pcre.x86_64 0:7.8-7.el6
Complete!
安装完后检查一下是否已经成功安装：
[root@leaf ~]# rpm -q pcre pcre-devel
pcre-7.8-7.el6.x86_64
pcre-devel-7.8-7.el6.x86_64
可以看到已经安装成功。
（2）安装Nginx依赖函数库openssl-devel
Nginx在使用HTTPS服务的时候要用到此模块，如果不安装openssl相关包，安装过程中是会报错的。
检查系统是否有安装openssl相关包：
[root@leaf ~]# rpm -q openssl openssl-devel
openssl-1.0.1e-15.el6.x86_64
package openssl-devel is not installed
可以看到只是安装了opensslopenssl-devel还没有安装使用yum安装如下：
[root@leaf ~]# yum install -y openssl-devel
......
Complete!
再次检查：
[root@leaf ~]# rpm -q openssl openssl-devel
openssl-1.0.1e-48.el6_8.4.x86_64
openssl-devel-1.0.1e-48.el6_8.4.x86_64
可以看到都已经成功安装上。
（3）下载Nginx软件包
这里使用的Nginx版本为1.6.3，下载方式如下：
[root@leaf ~]# pwd
/root
[root@leaf ~]# mkdir tools
[root@leaf ~]# cd tools/
[root@leaf tools]# wget http://nginx.org/download/nginx-1.6.3.tar.gz ......
100%[======================================>] 805,253 220K/s in 3.6s
2017-02-24 12:10:26 (220 KB/s) - anginx-1.6.3.tar.gza saved [805253/805253]
查看下载的Nginx软件包：
[root@leaf tools]# ll
total 788
-rw-r--r--. 1 root root 805253 Apr 8 2015 nginx-1.6.3.tar.gz
当然上面的方式是使用wget方式直接下载，前提是已经知道了Nginx的下载地址，也可以到官网下载，然后再上传到我们的CentOS操作系统上。
（4）开始安装Nginx
可以先在根目录下创建一个/application文件夹用来存放我们安装的软件：
[root@leaf ~]# mkdir /application
[root@leaf ~]# ls -d /application/
/application/
解压缩
将我们刚刚下载的Nginx软件包解压缩：
[root@leaf tools]# tar -zxvf nginx-1.6.3.tar.gz
......
[root@leaf tools]# ls
nginx-1.6.3 nginx-1.6.3.tar.gz
使用./configure指定编译参数
先创建一个nginx用户用来安装完成后运行nginx使用：
[root@leaf tools]# useradd nginx -s /sbin/nologin -M
[root@leaf tools]# tail -1 /etc/passwd
nginx:x:500:500::/home/nginx:/sbin/nologin
# -s参数后的/sbin/nologin指定不允许nginx进行登陆
# -M参数则是在创建该用户时不创建用户家目录
使用configure命令指定编译参数：
[root@leaf nginx-1.6.3]# ./configure --user=nginx --group=nginx --prefix=/application/nginx-1.6.3/ --with-http_stub_status_module --with-http_ssl_module
对于配置时使用的参数可以通过./configure --help来进行查询，上面使用的参数解析如下：
--prefix=PATH # 指定安装路径
--user=USER # 设置用户进程权限
--group=GROUP # 设置用户组进程权限
--with-http_stub_status_module # 激活状态信息
--with-http_ssl_module # 激活ssl功能
使用make进行编译
[root@leaf nginx-1.6.3]# make
......
检查编译是否成功：
[root@leaf nginx-1.6.3]# echo $?
0
返回0即说明编译成功。
使用make install安装
[root@leaf nginx-1.6.3]# make install
......
检查安装是否成功：
[root@leaf nginx-1.6.3]# echo $?
0
返回0即说明安装成功。
建立安装目录的软链接
[root@leaf nginx-1.6.3]# ln -s /application/nginx-1.6.3/ /application/nginx
[root@leaf nginx-1.6.3]# ls -l /application/
total 4
lrwxrwxrwx. 1 root root 25 Feb 24 12:32 nginx -> /application/nginx-1.6.3/
drwxr-xr-x. 6 root root 4096 Feb 24 12:28 nginx-1.6.3
到此Nginx的编译安装工作已经全部完成了，下面就需要对安装结果进行验证了即验证Nginx是否可以正常提供服务。
3.测试Nginx服务
（1）启动Nginx服务前检查配置文件语法
如下：
[root@leaf ~]# /application/nginx/sbin/nginx -t
nginx: the configuration file /application/nginx-1.6.3//conf/nginx.conf syntax is ok
nginx: configuration file /application/nginx-1.6.3//conf/nginx.conf test is successful
（2）启动Nginx服务
[root@leaf ~]# /application/nginx/sbin/nginx
如果在启动Nginx服务时出现了问题可以查看Nginx的日志/application/nginx/logs/error.log，再根据日志提供的信息来进行解决。
（3）验证Nginx服务是否正常
查看已开启的端口信息
[root@leaf ~]# netstat -lnp | grep 80
tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN 6772/nginx
unix 2 [ ACC ] STREAM LISTENING 9180 1/init @/com/ubuntu/upstart
可以看到Nginx已经在侦听80端口。
查看Nginx进程
[root@leaf ~]# ps aux | grep nginx
root 6772 0.0 0.1 45028 1140 ? Ss 12:34 0:00 nginx: master process /application/nginx/sbin/nginx
nginx 6773 0.0 0.1 45460 1716 ? S 12:34 0:00 nginx: worker process
root 6777 0.0 0.0 103256 832 pts/1 S+ 12:36 0:00 grep nginx
在宿主机上使用浏览器进行测试
在我们宿主机的浏览器上输入http://10.0.0.101/，查看测试结果
可以正常访问，当然前提是CentOS上的防火墙功能已经关闭。
使用wget命令和curl命令测试
wget命令：
[root@leaf tools]# wget 127.0.0.1
--2017-02-24 12:41:05-- http://127.0.0.1/ Connecting to 127.0.0.1:80... connected.
HTTP request sent, awaiting response... 200 OK
Length: 612 [text/html]
Saving to: aindex.htmla
100%[======================================>] 612 --.-K/s in 0s
2017-02-24 12:41:05 (44.1 MB/s) - aindex.htmla saved [612/612]
currl命令：
[root@leaf tools]# curl 127.0.0.1
<!DOCTYPE html>
<html>
<head>
<title>Welcome to nginx!</title>
<style>
body {

margin: 0 auto;
font-family: Tahoma, Verdana, Arial, sans-serif;
}
</style>
</head>
<body>
<h1>Welcome to nginx!</h1>
<p>If you see this page, the nginx web server is successfully installed and
working. Further configuration is required.</p>

Commercial support is available at
<a href="http://nginx.com/">nginx.com</a>.</p>
<p><em>Thank you for using nginx.</em></p>
</body>
</html>
从上面的结果可以说明Nginx已经正常部署并运行。
4.进一步测试修改Nginx显示的页面
通过修改/application/nginx/html下的index.html文件，我们就可以改变Nginx主页显示的内容，操作如下：
[root@leaf tools]# cd /application/nginx/html/
[root@leaf html]# ls
50x.html index.html
[root@leaf html]# mv index.html index.html.source
[root@leaf html]# echo "<h1>Hello, I'm xpleaf.</h1>">index.html
[root@leaf html]# ls
50x.html index.html index.html.source
[root@leaf html]# cat index.html
<h1>Hello, I'm xpleaf.</h1>
这时在宿主机操作系统上访问http://10.0.0.101/
（1）Nginx安装
1.安装Nginx依赖函数库pcre、openssl-devel
[root@leaf ~]# yum install -y pcre pcre-devel openssl openssl-devel
......
[root@leaf ~]# rpm -q pcre pcre-devel openssl openssl-devel
pcre-7.8-7.el6.x86_64
pcre-devel-7.8-7.el6.x86_64
openssl-1.0.1e-48.el6_8.4.x86_64
openssl-devel-1.0.1e-48.el6_8.4.x86_64
2.下载安装Nginx
这里使用Nginx1.6.3，如下：
# 下载Nginx

总用量 4
lrwxrwxrwx. 1 root root 25 3月 4 04:28 nginx -> /application/nginx-1.6.3/
drwxr-xr-x. 6 root root 4096 3月 4 04:27 nginx-1.6.3
（2）Nginx测试
1.启动Nginx
[root@leaf ~]# /application/nginx/sbin/nginx -t # 检查配置文件
nginx: the configuration file /application/nginx-1.6.3//conf/nginx.conf syntax is ok
nginx: configuration file /application/nginx-1.6.3//conf/nginx.conf test is successful
[root@leaf ~]# /application/nginx/sbin/nginx # 启动Nginx服务
2.CentOS上验证Nginx服务
[root@leaf ~]# netstat -lntup | grep 80
tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN 3929/nginx
[root@leaf ~]# curl localhost
<!DOCTYPE html>
<html>
<head>
<title>Welcome to nginx!</title>
<style>
body {

margin: 0 auto;
font-family: Tahoma, Verdana, Arial, sans-serif;
}
</style>
</head>
<body>
<h1>Welcome to nginx!</h1>
<p>If you see this page, the nginx web server is successfully installed and

<p><em>Thank you for using nginx.</em></p>
</body>
</html>
3.宿主机上验证Nginx服务
在宿主机浏览器上输入CentOS主机的IP地址10.0.0.101，如下：
（3）域名配置
因为要搭建一个博客服务，所以这里配置的域名为blog.xpleaf.org，操作过程如下：
1.最小化配置文件
[root@leaf ~]# cd /application/nginx/conf/
[root@leaf conf]# wc -l nginx.conf
117 nginx.conf
[root@leaf conf]# wc -l nginx.conf.default
117 nginx.conf.default
[root@leaf conf]# egrep -v "#|^$" nginx.conf.default >nginx.conf
[root@leaf conf]# wc -l nginx.conf
22 nginx.conf
[root@leaf conf]# cat nginx.conf
worker_processes 1;
events {
worker_connections 1024;
}
http {
include mime.types;
default_type application/octet-stream;
sendfile on;
keepalive_timeout 65;
server {
listen 80;
server_name localhost;
location / {
root html;
index index.html index.htm;
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}
}
}
2.修改配置文件
修改nginx.conf，并且增加配置文件extra/blog.conf，如下：
[root@leaf conf]# cat nginx.conf
worker_processes 1;
events {
worker_connections 1024;
}
http {
include mime.types;
default_type application/octet-stream;
sendfile on;
keepalive_timeout 65;
include extra/blog.conf;
}
[root@leaf conf]# cat extra/blog.conf
server {
listen 80;
server_name blog.xpleaf.org;
location / {
root html/blog;
index index.html index.htm;
}
}
3.创建域名对应的站点目录及文件
[root@leaf conf]# cd ../html/
[root@leaf html]# mkdir blog
[root@leaf html]# echo "This page is: blog.xpleaf.org">blog/index.html
[root@leaf html]# cat blog/index.html
This page is: blog.xpleaf.org
4.重启Nginx服务
[root@leaf html]# /application/nginx/sbin/nginx -t
nginx: the configuration file /application/nginx-1.6.3//conf/nginx.conf syntax is ok
[root@leaf html]# /application/nginx/sbin/nginx -s reload # 平滑重启
5.CentOS 6.5上进行测试
先修改/etc/hosts文件：
[root@leaf html]# echo "127.0.0.1 blog.xpleaf.org" >>/etc/hosts
[root@leaf html]# tail -1 /etc/hosts
127.0.0.1 blog.xpleaf.org
再使用命令测试：
[root@leaf html]# curl blog.xpleaf.org
This page is: blog.xpleaf.org
[root@leaf html]# wget blog.xpleaf.org
--2017-03-04 04:58:42-- http://blog.xpleaf.org/ 正在解析主机 blog.xpleaf.org... 127.0.0.1
正在连接 blog.xpleaf.org|127.0.0.1|:80... 已连接。
已发出 HTTP 请求，正在等待回应... 200 OK
长度：30 [text/html]
正在保存至: “index.html.1”
100%[====================================>] 30 --.-K/s in 0s
2017-03-04 04:58:42 (2.14 MB/s) - 已保存 “index.html.1” [30/30])
6.宿主机Windows 7上进行测试
同样是先修改hosts文件，Windows 7的hosts文件在C:\Windows\System32\drivers\etc，同样添加下面一行：
1
10.0.0.101 blog.xpleaf.org
使用浏览器访问blog.xpleaf.org，如下：
3.LNMP环境搭建：MySQL安装与基本安全优化
这里采用二进制安装的方式来安装MySQL，安装的版本为：MySQL Server 5.5.54，可以在https://dev.mysql.com/downloads/mysql/5.5.html#downloads中下载。
MySQL安装完成后会做一些基本的安全优化。
（1）MySQL安装
1.创建MySQL用户的账号
[root@leaf ~]# groupadd mysql
[root@leaf ~]# useradd -s /sbin/nologin -g mysql -M mysql
[root@leaf ~]# tail -1 /etc/passwd
mysql:x:501:501::/home/mysql:/sbin/nologin
2.下载MySQL
可以使用wget来进行安装，也可以先下载到Windows 7上，然后使用SecureCRT，在CentOS上使用rz命令（需要使用yum install -y lrzsz命令安装）上传到我们的CentOS上，其实不管哪一种方式，只要有方式获取到该安装包就可以了，下面使用的是wget获取安装包的方式：
[root@leaf tools]# wget
[root@leaf tools]# ls -l mysql-5.5.54-linux2.6-x86_64.tar.gz
-rw-r--r--. 1 root root 185911232 3月 3 13:34 mysql-5.5.54-linux2.6-x86_64.tar.gz
3.解压并移到指定目录
[root@leaf tools]# tar xf mysql-5.5.54-linux2.6-x86_64.tar.gz
[root@leaf tools]# mv mysql-5.5.54-linux2.6-x86_64 /application/mysql-5.5.54
[root@leaf tools]# ln -s /application/mysql-5.5.54/ /application/mysql
[root@leaf tools]# ls -l /application/
总用量 8
lrwxrwxrwx. 1 root root 26 3月 4 06:43 mysql -> /application/mysql-5.5.54/
drwxr-xr-x. 13 root root 4096 3月 4 06:42 mysql-5.5.54
lrwxrwxrwx. 1 root root 25 3月 4 04:28 nginx -> /application/nginx-1.6.3/
drwxr-xr-x. 11 root root 4096 3月 4 04:30 nginx-1.6.3
4.初始化MySQL配置文件
[root@leaf mysql]# cp support-files/my-small.cnf /etc/my.cnf
cp：是否覆盖"/etc/my.cnf"？ y
5.初始化MySQL数据库文件
[root@leaf mysql]# mkdir -p /application/mysql/data/
[root@leaf mysql]# chown -R mysql.mysql /application/mysql
[root@leaf mysql]# yum install -y libaio # 安装MySQL依赖函数库，否则下面的初始化会失败
[root@leaf mysql]# /application/mysql/scripts/mysql_install_db --basedir=/application/mysql --datadir=/application/mysql/data --user=mysql
......
# 输出结果可以看到两个OK，即说明初始化成功
[root@leaf mysql]# echo $? # 或者通过该命令，输出为0，即说明上一个步骤的命令执行成功
0
# 上面之后可以看到/application/mysql/data/目录下生成的数据库文件
6.配置并启动MySQL数据库
#（1）设置MySQL启动脚本
[root@leaf mysql]# cp support-files/mysql.server /etc/init.d/mysqld
[root@leaf mysql]# chmod +x /etc/init.d/mysqld
[root@leaf mysql]# ls -l /etc/init.d/mysqld
-rwxr-xr-x. 1 root root 10875 3月 4 06:56 /etc/init.d/mysqld
#（2）替换启动脚本中MySQL默认的安装路径/usr/local/mysql
[root@leaf mysql]# sed -i 's#/usr/local/mysql#/application/mysql#g' /application/mysql/bin/mysqld_safe /etc/init.d/mysqld
#（3）启动MySQL数据库
[root@leaf mysql]# /etc/init.d/mysqld start
Starting MySQL.Logging to '/application/mysql/data/leaf.err'.
... SUCCESS!
#（4）检查MySQL数据库是否启动
[root@leaf mysql]# netstat -lntup | grep mysql
tcp 0 0 0.0.0.0:3306 0.0.0.0:* LISTEN 4400/mysqld
#（5）查看日志
[root@leaf mysql]# tail -10 /application/mysql/data/leaf.err

#（6）设置MySQL开机启动
[root@leaf mysql]# chkconfig --add mysqld
[root@leaf mysql]# chkconfig mysqld on
[root@leaf mysql]# chkconfig --list mysqld
mysqld 0:关闭 1:关闭 2:启用 3:启用 4:启用 5:启用 6:关闭
#（7）配置mysql命令的全局使用路径（注意这里配置的是命令，前面配置的只是启动脚本）
[root@leaf mysql]# echo 'export PATH=/application/mysql/bin:$PATH' >>/etc/profile
[root@leaf mysql]# source /etc/profile
[root@leaf mysql]# echo $PATH
/application/mysql/bin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin
#（8）登陆MySQL测试
[root@leaf mysql]# mysql

到此为此，MySQL也安装完成了！
4.LNMP环境搭建：PHP（FastCGI方式）安装、配置与启动
（1）安装PHP依赖函数库
1.安装lib库
需要安装的lib库如下：
zlib-devel libxml2-devel libjpeg-devel libjpeg-turbo-devel libiconv-devel
freetype-devel libpng-devel gd-devel libcurl-devel libxslt-devel
其中除了libiconv库外，其他都可以通过yum的方式进行安装，安装如下：
# 使用yum安装除libiconv-devel之外的其它lib库
[root@leaf mysql]# yum install -y zlib-devel libxml2-devel libjpeg-devel libjpeg-turbo-devel libiconv-devel freetype-devel libpng-devel gd-devel libcurl-devel libxslt-devel
# 编译安装libiconv-devel
[root@leaf tools]# wget
[root@leaf tools]# tar zxf libiconv-1.14.tar.gz
[root@leaf tools]# cd libiconv-1.14
[root@leaf libiconv-1.14]# ./configure --prefix=/usr/local/libiconv
[root@leaf libiconv-1.14]# make
[root@leaf libiconv-1.14]# make install
2.安装libmcrypt库
[root@leaf ~]# wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-6.repo [root@leaf ~]# yum install -y libmcrypt-devel
3.安装mhash加密扩展库
[root@leaf ~]# yum install -y mhash
4.安装mcrypt加密扩展库
[root@leaf ~]# yum install -y mcrypt
（2）安装PHP
使用的PHP版本号为5.3.27，如下：
1.下载PHP安装包
[root@leaf tools]# wget http://cn2.php.net/get/php-5.3.27.tar.gz/from/this/mirror [root@leaf tools]# mv mirror php-5.3.27.tar.gz
[root@leaf tools]# ls -l php-5.3.27.tar.gz
-rw-r--r--. 1 root root 15008639 1月 21 2015 php-5.3.27.tar.gz
2.解压缩
[root@leaf tools]# tar zxf php-5.3.27.tar.gz
[root@leaf tools]# cd php-5.3.27
[root@leaf php-5.3.27]# pwd
/root/tools/php-5.3.27
3.配置PHP的安装参数
配置项非常多，如下：
./configure \
--prefix=/application/php5.3.27 \
--with-mysql=/application/mysql \
--with-iconv-dir=/usr/local/libiconv \
--with-freetype-dir \
--with-jpeg-dir \
--with-png-dir \
--with-zlib \
--with-libxml-dir=/usr \
--enable-xml \
--disable-rpath \
--enable-safe-mode \
--enable-bcmath \
--enable-shmop \
--enable-sysvsem \
--enable-inline-optimization \
--with-curl \
--with-curlwrappers \
--enable-mbregex \
--enable-fpm \
--enable-mbstring \
--with-mcrypt \
--with-gd \
--enable-gd-native-ttf \
--with-openssl \
--with-mhash \
--enable-pcntl \
--enable-sockets \
--with-xmlrpc \
--enable-zip \
--enable-soap \
--enable-short-tags \
--enable-zend-multibyte \
--enable-static \
--with-xsl \
--with-fpm-user=nginx \
--with-fpm-group=nginx \
--enable-ftp
可以将其直接复制到命令行进行配置，这样就可以减少出错的概率：
[root@leaf php-5.3.27]# ./configure \
> --prefix=/application/php5.3.27 \
> --with-mysql=/application/mysql \
> --with-iconv-dir=/usr/local/libiconv \
> --with-freetype-dir \

ln -s -f /application/php5.3.27/bin/phar.phar /application/php5.3.27/bin/phar
Installing PDO headers: /application/php5.3.27/include/php/ext/pdo/
......
[root@leaf php-5.3.27]# echo $?
0
（3）配置与启动PHP
1.设置PHP安装目录软链接
[root@leaf php-5.3.27]# ln -s /application/php5.3.27/ /application/php
[root@leaf php-5.3.27]# ls -l /application/php
lrwxrwxrwx. 1 root root 23 3月 4 08:59 /application/php -> /application/php5.3.27/
2.拷贝PHP配置文件到PHP默认目录
[root@leaf php-5.3.27]# cp php.ini-production /application/php/lib/php.ini
[root@leaf php-5.3.27]# ls -l /application/php/lib/php.ini
-rw-r--r--. 1 root root 69627 3月 4 09:00 /application/php/lib/php.ini
3.配置php-fpm.conf文件
[root@leaf php-5.3.27]# cd /application/php/etc/
[root@leaf etc]# ls
pear.conf php-fpm.conf.default
[root@leaf etc]# cp php-fpm.conf.default php-fpm.conf
4.启动PHP服务php-fpm
[root@leaf etc]# /application/php/sbin/php-fpm
5.检查启动进程与侦听端口号
[root@leaf etc]# ps -ef | grep php-fpm
root 129256 1 0 09:05 ? 00:00:00 php-fpm: master process (/application/php5.3.27/etc/php-fpm.conf)
nginx 129257 129256 0 09:05 ? 00:00:00 php-fpm: pool www

root 129260 13743 0 09:06 pts/1 00:00:00 grep php-fpm
[root@leaf etc]# netstat -lntup | grep 9000
tcp 0 0 127.0.0.1:9000 0.0.0.0:* LISTEN 129256/php-fpm
至此，PHP也安装完成了！LNMP的各个组件都安装好了，下面就要对LNMP环境进行测试了。
5.LNMP环境测试
（1）配置Nginx支持PHP程序请求访问
1.查看当前Nginx配置
[root@leaf etc]# cd /application/nginx/conf/
[root@leaf conf]# cat nginx.conf
worker_processes 1;
events {
worker_connections 1024;
}
http {
include mime.types;
default_type application/octet-stream;
sendfile on;
keepalive_timeout 65;
include extra/blog.conf;
}
[root@leaf conf]# cat extra/blog.conf
server {
listen 80;
server_name blog.xpleaf.org;
location / {
root html/blog;
index index.html index.htm;
}
}
2.修改extra/blog.conf配置文件
[root@leaf conf]# cat extra/blog.conf
server {
listen 80;
server_name blog.xpleaf.org;
location / {
root html/blog;
index index.html index.htm;
}
location ~ .*\.(php|php5)?$ {
root html/blog;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
include fastcgi.conf;
}
}
3.检查并启动Nginx
[root@leaf conf]# /application/nginx/sbin/nginx -t
nginx: the configuration file /application/nginx-1.6.3//conf/nginx.conf syntax is ok
nginx: configuration file /application/nginx-1.6.3//conf/nginx.conf test is successful
[root@leaf conf]# /application/nginx/sbin/nginx -s reload
（2）测试LNMP环境是否生效
1.配置域名站点目录
[root@leaf conf]# cd /application/nginx/html/blog/
[root@leaf blog]# echo "<?php phpinfo(); ?>" >test_info.php
[root@leaf blog]# cat test_info.php
<?php phpinfo(); ?>
2.宿主机上在浏览器中输入地址http://blog.xpleaf.org/test_info.php进行访问
（3）测试PHP连接MySQL是否正常
1.编辑text_mysql.php
[root@leaf blog]# cat test_mysql.php
<?php
$link_id=mysql_connect('localhost', 'root', '123456');
if($link_id){
echo "mysql succesful by xpleaf !";
}else{
echo mysql_error();
}
?>
2.宿主机上在浏览器中输入地址http://blog.xpleaf.org/test_mysql.php进行访问
至此，LNMP环境搭建与测试完成了，下面就可以开始部署WordPress了！
6.部署WordPress
（1）MySQL数据库准备
1.登陆mysql
[root@leaf blog]# mysql -u root -p
Enter password:

+--------------------+
4 rows in set (0.00 sec)
3.创建wordpress blog管理用户
mysql> grant all on wordpress.* to wordpress@'localhost' identified by '123456';
Query OK, 0 rows affected (0.08 sec)
mysql> show grants for wordpress@'localhost';
+------------------------------------------------------------------------------------------------------------------+
| Grants for wordpress@localhost |
+------------------------------------------------------------------------------------------------------------------+
| GRANT USAGE ON *.* TO 'wordpress'@'localhost' IDENTIFIED BY PASSWORD '*6BB4837EB74329105EE4568DDA7DC67ED2CA2AD9' |
| GRANT ALL PRIVILEGES ON `wordpress`.* TO 'wordpress'@'localhost' |
+------------------------------------------------------------------------------------------------------------------+
2 rows in set (0.00 sec)
4.刷新MySQL用户权限
mysql> flush privileges;
Query OK, 0 rows affected (0.31 sec)
5.检查MySQL登录用户
mysql> select user,host from mysql.user;
+-----------+-----------+
| user | host |
+-----------+-----------+
| root | 127.0.0.1 |
| root | localhost |
| wordpress | localhost |
+-----------+-----------+
3 rows in set (0.00 sec)
（2）Nginx配置准备
1.修改blog.conf配置文件
[root@leaf conf]# cat extra/blog.conf
server {
listen 80;
server_name blog.xpleaf.org;
location / {
root html/blog;
index index.php index.html index.htm;
}
location ~ .*\.(php|php5)?$ {
root html/blog;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
include fastcgi.conf;
}
}
# 相比前面的配置文件，只是在/下添加了index.php
# 不过需要注意的是，index.php一定要放在index关键字之后，
# 这样访问blog.xpleaf.org时，才会打开我们的WordPress页面
2.重启Nginx服务
[root@leaf conf]# /application/nginx/sbin/nginx -s reload
（3）配置WordPress
1.获取WordPress安装包
[root@leaf tools]# wget
[root@leaf tools]# ls -lh wordpress-4.7.2-zh_CN.tar.gz
-rw-r--r--. 1 root root 8.1M 1月 28 08:53 wordpress-4.7.2-zh_CN.tar.gz
2.解压缩与配置站点目录
[root@leaf tools]# cp wordpress-4.7.2-zh_CN.tar.gz /application/nginx/html/blog/
[root@leaf tools]# cd /application/nginx/html/blog/
[root@leaf blog]# tar zxf wordpress-4.7.2-zh_CN.tar.gz
[root@leaf blog]# ls
index.html test_mysql.php wordpress-4.7.2-zh_CN.tar.gz
test_info.php wordpress
[root@leaf blog]# rm -rf test_* wordpress-4.7.2-zh_CN.tar.gz # 删除无用的文件
[root@leaf blog]# ls
index.html wordpress
[root@leaf blog]# mv wordpress/* ./ # 将wordpress程序移到当前blog目录下
[root@leaf blog]# ls
index.html wp-admin wp-includes wp-signup.php
index.php wp-blog-header.php wp-links-opml.php wp-trackback.php
license.txt wp-comments-post.php wp-load.php xmlrpc.php
readme.html wp-config-sample.php wp-login.php
wordpress wp-content wp-mail.php
wp-activate.php wp-cron.php wp-settings.php
[root@leaf blog]# ls -l
总用量 196
-rw-r--r--. 1 root root 30 3月 4 04:54 index.html
-rw-r--r--. 1 nobody 65534 418 9月 25 2013 index.php
-rw-r--r--. 1 nobody 65534 19935 1月 3 02:51 license.txt
-rw-r--r--. 1 nobody 65534 6956 1月 28 08:53 readme.html
drwxr-xr-x. 2 nobody 65534 4096 3月 4 09:50 wordpress
......
3.对blog下所有文件授予nginx用户和组的权限
[root@leaf blog]# chown -R nginx.nginx ../blog/
[root@leaf blog]# ls -l
总用量 196
-rw-r--r--. 1 nginx nginx 30 3月 4 04:54 index.html
-rw-r--r--. 1 nginx nginx 418 9月 25 2013 index.php
-rw-r--r--. 1 nginx nginx 19935 1月 3 02:51 license.txt
-rw-r--r--. 1 nginx nginx 6956 1月 28 08:53 readme.html
drwxr-xr-x. 2 nginx nginx 4096 3月 4 09:50 wordpress
......
（4）安装WordPress
在宿主机浏览器上输入地址：http://blog.xpleaf.org，如下：
接下来的安装都是非常人性化的，点击“现在就开始”，出现下面的页面：
填好信息后，点击“提交”，如下：
点击“进行安装”，接下来就会让我们填写一些信息，如下：
点击“安装WordPress”，之后就会显示如下页面：
显示上面的页面，就说明我们的WordPress安装成功了！接下来就可以好好管理自己的个人WordPress博客站点了！
7.下一步要做什么
可以在云主机上，如腾讯云或者阿里云上搭建LNMP环境，再部署一个WordPress博客程序，为了达到域名访问的效果，可以购买一个域名，然后自己搭建DNS服务器，这会是非常不错的体验！
接下来就可以考虑对LNMP进行优化了。
Nginx功能非常强大，仅仅是通过主配置文件nginx.conf的使用就可以体现出来，为了方便学习和查漏，将其主配置文件的完整内容列出来，并加上个人的一些理解以作为笔记，从而去加深记忆。

解决客户机访问头部信息过长的问题。
当访问时输入的地址头部信息过长时报414错误时，查看buffer,默认时为1，改成下面这两行就行。若是发现本来buffers就设置为4 4k时，
不用再改了，可能是别人恶意***，最大 不要改到4 8k)

在客户机上做缓存
在服务器中设置格式为pdf|jpg|mp3|png的文件，使打开该格式页面文件的客户机浏览器中缓存30天（一般只做静态缓存）
[root@proxe ~]# vim /usr/local/nginx/conf/nginx.conf
location ~ \.(pdf|jpg|mp3|png) ${
expires 30d;
}
[root@proxe ~]# cp knowledge\ point\(2.1\).pdf /usr/local/nginx/html/a.pdf
[root@proxe ~]# nginx -s reload
[root@host ~]# firefox http://192.168.4.5/a.pdf
在打开的浏览器（firefox）地址栏中：输入 about:cache 可以看到刚打开的页面 找到它可以看到从哪天保存到哪天。（做实验时先把浏览器缓存清空）

防止盗链
Referer：告诉服务器，从哪里来
访问新浪：可以直接访问新浪，也可从百度中链接过去，但referer不一样。
------>sina
baidu ----->sina
referer:www.baidu.com
referer:www.sina.com
www.youku.com www.letv.com
www.bird.org :所有资源（做链接），搜索功能 目的是扩大自己网站的影响和点击，让别人知道自己域名。
防止盗链
vaild_referers (有效的 允许链接)
if 拒绝的
实验操作：
location ~*\. (pdf|jpg|mp3|png|flv) ${
vaild_referers none blocked www.tarena.com;
if($invalid_referer){
rewrite ^/ http:www.a.com/a.html
}
}

使用Nginx可以配置基于域名的虚拟主机、基于端口的虚拟主机和基于端口的虚拟主机，比较常用的是基于域名的虚拟主机，这里要做的配置是基于域名的虚拟主机，并且是配置多个基于域名的虚拟主机。
2.配置一个基于域名的虚拟主机与测试
先启动Nginx，验证服务是否正常：
[root@leaf ~]# /application/nginx/sbin/nginx
[root@leaf ~]# netstat -lnp | grep 80

从上面的输出可以看到，此时Nginx是可以正常运行和提供服务的。
（1）实验准备：最小化Nginx的主配置文件nginx.conf
Nginx的配置文件在安装目录下的conf目录中：
[root@leaf ~]# tree /application/nginx
/application/nginx
|-- client_body_temp
|-- conf
| |-- fastcgi.conf
| |-- fastcgi.conf.default
| |-- fastcgi_params
| |-- fastcgi_params.default
| |-- koi-utf
| |-- koi-win
| |-- mime.types
| |-- mime.types.default
| |-- nginx.conf
| |-- nginx.conf.default
| |-- scgi_params
| |-- scgi_params.default
| |-- uwsgi_params
| |-- uwsgi_params.default
| `-- win-utf
|-- fastcgi_temp
|-- html
| |-- 50x.html
| |-- index.html
| `-- index.html.source
|-- logs
| |-- access.log
| |-- error.log
| `-- nginx.pid
|-- proxy_temp
|-- sbin
| `-- nginx
|-- scgi_temp
`-- uwsgi_temp
nginx.conf便是主配置文件，nginx.conf.default则是它的备份，该配置文件有数百行：
1
2
[root@leaf conf]# wc -l nginx.conf
117 nginx.conf
为了学习的方便，可以考虑将其注释内容去掉：
[root@leaf conf]# egrep -v "#|^$" nginx.conf.default >nginx.conf
[root@leaf conf]# cat nginx.conf
worker_processes 1;
events {
worker_connections 1024;
}
http {
include mime.types;
default_type application/octet-stream;
sendfile on;
keepalive_timeout 65;
server {
listen 80;
server_name localhost;
location / {
root html;
index index.html index.htm;
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}
}
}
[root@leaf conf]# wc -l nginx.conf
22 nginx.conf
去掉了注释和空白行后只有22行，就很方便我们待会做实验时进行配置了。
（2）修改配置文件
假设我们的Nginx为站点www.xpleaf.cn服务，则可以将主配置文件修改为如下：
[root@leaf conf]# cat nginx.conf
worker_processes 1;
events {
worker_connections 1024;
}
http {
include mime.types;
default_type application/octet-stream;
sendfile on;
keepalive_timeout 65;
server {
listen 80;
server_name www.xpleaf.com;
location / {
root html/www;
index index.html index.htm;
}
}
}
主要是修改了第12行和第14行，其中第14行说明该站点的根目录的html文件在html/www/目录中。
（3）创建域名对应的站点目录及文件
[root@leaf nginx]# cd html/
[root@leaf html]# mkdir www
[root@leaf html]# echo "This page is: www.xpleaf.cn">www/index.html
[root@leaf html]# cat www/index.html
This page is: www.xpleaf.cn
（4）重新启动Nginx服务
[root@leaf html]# /application/nginx/sbin/nginx -t # 检查Nginx配置语法
nginx: the configuration file /application/nginx-1.6.3//conf/nginx.conf syntax is ok
nginx: configuration file /application/nginx-1.6.3//conf/nginx.conf test is successful
[root@leaf html]# /application/nginx/sbin/nginx -s reload # 优雅重启Nginx
（5）在CentOS 6.5上进行测试
因为上面我们设置的域名www.xpleaf.cn实际是可能不存在，但为了达到测试的目的，即当访问www.xpleaf.cn时，能够解析到我们CentOS上的IP地址，从而可以访问其上面的Nginx服务，达到访问Nginx虚拟主机的目的，所以在CentOS上进行测试时，我们需要修改/etc/hosts文件，让www.xpleaf.cn解析为CentOS的IP地址：
[root@leaf html]# echo "127.0.0.1 www.xpleaf.cn" >>/etc/hosts
[root@leaf html]# tail -1 /etc/hosts
127.0.0.1 www.xpleaf.cn
此时，在CentOS上使用curl命令和wget命令来访问www.xpleaf.cn，查看测试结果：
[root@leaf html]# curl www.xpleaf.cn
This page is: www.xpleaf.cn
[root@leaf html]# wget www.xpleaf.cn
--2017-02-24 13:58:29-- http://www.xpleaf.cn/ Resolving www.xpleaf.cn... 127.0.0.1
Connecting to www.xpleaf.cn|127.0.0.1|:80... connected.
HTTP request sent, awaiting response... 200 OK
Length: 28 [text/html]
Saving to: `index.html.1'

2017-02-24 13:58:29 (2.24 MB/s) - `index.html.1' saved [28/28]
从输出结果可以知道，此时Nginx成功地为域名为www.xpleaf.cn的虚拟主机提供了服务。
（6）在Windows 7主机上进行测试
为了达到前面说的目的，在Windows操作系统上同样需要修改hosts文件，Windows 7的hosts文件在C:\Windows\System32\drivers\etc，同样添加下面一行：
1
10.0.0.101 www.xpleaf.cn
这时在浏览器中输入地址www.xpleaf.cn，查看返回的结果：
wKiom1ixs6jzW6yTAAAjHHKgIE8656.png
可以看到，可以正常访问。
3.配置多个基于域名的虚拟主机与测试
上面的实验中只有一个站点www.xpleaf.cn，假如还有两个站点bbs.xpleaf.cn和log.xpleaf.cn，
同样需要Nginx来提供服务，这时就需要配置多个基于域名的虚拟主机了，不过有了上面的基础后，下面
的操作就会容易很多，因为思路都是一样的。
（1）修改主配置文件nginx.conf
在前面的基础上，修改为如下：
[root@leaf conf]# cat nginx.conf
worker_processes 1;
events {
worker_connections 1024;
}
http {
include mime.types;
default_type application/octet-stream;
sendfile on;
keepalive_timeout 65;
server {
listen 80;
server_name www.xpleaf.com;
location / {
root html/www;
index index.html index.htm;
}
}
server {
listen 80;
server_name bbs.xpleaf.com;
location / {
root html/bbs;
index index.html index.htm;
}
}
server {
listen 80;
server_name blog.xpleaf.com;
location / {
root html/blog;
index index.html index.htm;
}
}
}
（2）创建域名对应的站点目录及文件
[root@leaf html]# mkdir bbs
[root@leaf html]# echo "This page is: bbs.xpleaf.cn" >bbs/index.html
[root@leaf html]# mkdir blog
[root@leaf html]# echo "This page is: blog.xpleaf.cn" >blog/index.html
[root@leaf html]# cat bbs/index.html blog/index.html
This page is: bbs.xpleaf.cn
This page is: blog.xpleaf.cn
（3）重新启动Nginx服务
[root@leaf html]# /application/nginx/sbin/nginx -t # 检查Nginx配置语法
nginx: the configuration file /application/nginx-1.6.3//conf/nginx.conf syntax is ok
nginx: configuration file /application/nginx-1.6.3//conf/nginx.conf test is successful
[root@leaf html]# /application/nginx/sbin/nginx -s reload # 优雅重启Nginx
（4）在CentOS 6.5上进行测试
在原来基础上，修改/etc/hosts文件，在127.0.0.1地址后添加bbs.xpleaf.cn和blog.xpleaf.cn两个域名：
[root@leaf html]# tail -1 /etc/hosts
127.0.0.1 www.xpleaf.cn bbs.xpleaf.cn blog.xpleaf.cn
使用curl命令和wget命令进行测试：
[root@leaf html]# curl bbs.xpleaf.cn
This page is: www.xpleaf.cn
[root@leaf html]# curl blog.xpleaf.cn
This page is: www.xpleaf.cn
[root@leaf html]# wget bbs.xpleaf.cn
--2017-02-24 14:19:54-- http://bbs.xpleaf.cn/ Resolving bbs.xpleaf.cn... 127.0.0.1
Connecting to bbs.xpleaf.cn|127.0.0.1|:80... connected.
HTTP request sent, awaiting response... 200 OK
Length: 28 [text/html]

[root@leaf html]# wget blog.xpleaf.cn
--2017-02-24 14:20:00-- http://blog.xpleaf.cn/ Resolving blog.xpleaf.cn... 127.0.0.1
Connecting to blog.xpleaf.cn|127.0.0.1|:80... connected.

2017-02-24 14:20:00 (2.24 MB/s) - `index.html.3' saved [28/28]
从上面结果可以知道，Nginx为各个虚拟主机正常提供服务。
（5）在Windows 7主机上进行测试
在原来基础上，修改hosts文件，如下：
1
10.0.0.101 www.xpleaf.cn bbs.xpleaf.cn blog.xpleaf.cn
在浏览器上分别访问各个域名，查看其返回结果：
访问www.xpleaf.cn:
访问bbs.xpleaf.cn:
访问blog.xpleaf.cn:
可以看到访问每个域名都返回了期待的页面，说明测试成功！
6.进阶：Nginx虚拟主机的别名配置
所以虚拟主机别名，就是为虚拟主机设置除了主域名以外的一个或多个域名名字，这样就能实现用户访问的多个域名对应同一个虚拟主机网站的功能。
以www.xpleaf.cn为例，希望添加一个别名xpleaf.cn，这样当访问xpleaf.cn时，和访问www.xpleaf.cn得到的结果是一样的。
其实配置的思路非常简单，只需要在上面nginx.conf配置文件中www.xpleaf.cn的server域中再添加一个xpleaf.cn的域名就可以了，如下：
server {
listen 80;
server_name www.xpleaf.com xpleaf.cn;
location / {
root html/www;
index index.html index.htm;
}
}
测试的话依然按照前面的方法进行，即先检查Nginx配置文件、平滑重启Nginx服务、配置hosts文件，最后通过命令行或浏览器的方式进行验证，因为跟前面是一样的，所以这里就不展开了。
5.下一步要做什么
可以考虑配置与测试基于端口的虚拟主机和基于IP地址的虚拟主机，其实只要把上面的弄清楚了，再做这些配置就会容易很多了。

}
}
2.编译安装Nginx
（1）安装Nginx依赖函数库pcre
pcre为“perl兼容正则表达式”perl compatible regular expresssions,安装其是为了使Nginx支持具备URI重写功能的rewrite模块，如果不安装Nginx将无法使用rewrite模块功能，但是该功能却十分有用和常用。
检查系统中是否有安装：
[root@leaf ~]# rpm -q pcre pcre-devel
上面可以看到并没有安装使用yum方式安装如下：
[root@leaf ~]# yum install pcre pcre-devel -y
......
Installed:
pcre-devel.x86_64 0:7.8-7.el6
Updated:
pcre.x86_64 0:7.8-7.el6
Complete!
安装完后检查一下是否已经成功安装：
[root@leaf ~]# rpm -q pcre pcre-devel
pcre-7.8-7.el6.x86_64
pcre-devel-7.8-7.el6.x86_64
可以看到已经安装成功。
（2）安装Nginx依赖函数库openssl-devel
Nginx在使用HTTPS服务的时候要用到此模块，如果不安装openssl相关包，安装过程中是会报错的。
检查系统是否有安装openssl相关包：
[root@leaf ~]# rpm -q openssl openssl-devel
openssl-1.0.1e-15.el6.x86_64
package openssl-devel is not installed
可以看到只是安装了opensslopenssl-devel还没有安装使用yum安装如下：
[root@leaf ~]# yum install -y openssl-devel
......
Complete!
再次检查：
[root@leaf ~]# rpm -q openssl openssl-devel
openssl-1.0.1e-48.el6_8.4.x86_64
openssl-devel-1.0.1e-48.el6_8.4.x86_64
可以看到都已经成功安装上。
（3）下载Nginx软件包
这里使用的Nginx版本为1.6.3，下载方式如下：
[root@leaf ~]# pwd
/root
[root@leaf ~]# mkdir tools
[root@leaf ~]# cd tools/
[root@leaf tools]# wget http://nginx.org/download/nginx-1.6.3.tar.gz ......
100%[======================================>] 805,253 220K/s in 3.6s
2017-02-24 12:10:26 (220 KB/s) - anginx-1.6.3.tar.gza saved [805253/805253]
查看下载的Nginx软件包：
[root@leaf tools]# ll
total 788
-rw-r--r--. 1 root root 805253 Apr 8 2015 nginx-1.6.3.tar.gz
当然上面的方式是使用wget方式直接下载，前提是已经知道了Nginx的下载地址，也可以到官网下载，然后再上传到我们的CentOS操作系统上。
（4）开始安装Nginx
可以先在根目录下创建一个/application文件夹用来存放我们安装的软件：
[root@leaf ~]# mkdir /application
[root@leaf ~]# ls -d /application/
/application/
解压缩
将我们刚刚下载的Nginx软件包解压缩：
[root@leaf tools]# tar -zxvf nginx-1.6.3.tar.gz
......
[root@leaf tools]# ls
nginx-1.6.3 nginx-1.6.3.tar.gz
使用./configure指定编译参数
先创建一个nginx用户用来安装完成后运行nginx使用：
[root@leaf tools]# useradd nginx -s /sbin/nologin -M
[root@leaf tools]# tail -1 /etc/passwd
nginx:x:500:500::/home/nginx:/sbin/nologin
# -s参数后的/sbin/nologin指定不允许nginx进行登陆
# -M参数则是在创建该用户时不创建用户家目录
使用configure命令指定编译参数：
[root@leaf nginx-1.6.3]# ./configure --user=nginx --group=nginx --prefix=/application/nginx-1.6.3/ --with-http_stub_status_module --with-http_ssl_module
对于配置时使用的参数可以通过./configure --help来进行查询，上面使用的参数解析如下：
--prefix=PATH # 指定安装路径
--user=USER # 设置用户进程权限
--group=GROUP # 设置用户组进程权限
--with-http_stub_status_module # 激活状态信息
--with-http_ssl_module # 激活ssl功能
使用make进行编译
[root@leaf nginx-1.6.3]# make
......
检查编译是否成功：
[root@leaf nginx-1.6.3]# echo $?
0
返回0即说明编译成功。
使用make install安装
[root@leaf nginx-1.6.3]# make install
......
检查安装是否成功：
[root@leaf nginx-1.6.3]# echo $?
0
返回0即说明安装成功。
建立安装目录的软链接
[root@leaf nginx-1.6.3]# ln -s /application/nginx-1.6.3/ /application/nginx
[root@leaf nginx-1.6.3]# ls -l /application/
total 4
lrwxrwxrwx. 1 root root 25 Feb 24 12:32 nginx -> /application/nginx-1.6.3/
drwxr-xr-x. 6 root root 4096 Feb 24 12:28 nginx-1.6.3
到此Nginx的编译安装工作已经全部完成了，下面就需要对安装结果进行验证了即验证Nginx是否可以正常提供服务。
3.测试Nginx服务
（1）启动Nginx服务前检查配置文件语法
如下：
[root@leaf ~]# /application/nginx/sbin/nginx -t
nginx: the configuration file /application/nginx-1.6.3//conf/nginx.conf syntax is ok
nginx: configuration file /application/nginx-1.6.3//conf/nginx.conf test is successful
（2）启动Nginx服务
[root@leaf ~]# /application/nginx/sbin/nginx
如果在启动Nginx服务时出现了问题可以查看Nginx的日志/application/nginx/logs/error.log，再根据日志提供的信息来进行解决。
（3）验证Nginx服务是否正常
查看已开启的端口信息
[root@leaf ~]# netstat -lnp | grep 80
tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN 6772/nginx
unix 2 [ ACC ] STREAM LISTENING 9180 1/init @/com/ubuntu/upstart
可以看到Nginx已经在侦听80端口。
查看Nginx进程
[root@leaf ~]# ps aux | grep nginx
root 6772 0.0 0.1 45028 1140 ? Ss 12:34 0:00 nginx: master process /application/nginx/sbin/nginx
nginx 6773 0.0 0.1 45460 1716 ? S 12:34 0:00 nginx: worker process
root 6777 0.0 0.0 103256 832 pts/1 S+ 12:36 0:00 grep nginx
在宿主机上使用浏览器进行测试
在我们宿主机的浏览器上输入http://10.0.0.101/，查看测试结果
可以正常访问，当然前提是CentOS上的防火墙功能已经关闭。
使用wget命令和curl命令测试
wget命令：
[root@leaf tools]# wget 127.0.0.1
--2017-02-24 12:41:05-- http://127.0.0.1/ Connecting to 127.0.0.1:80... connected.

</body>
</html>
从上面的结果可以说明Nginx已经正常部署并运行。
4.进一步测试修改Nginx显示的页面
通过修改/application/nginx/html下的index.html文件，我们就可以改变Nginx主页显示的内容，操作如下：
[root@leaf tools]# cd /application/nginx/html/
[root@leaf html]# ls
50x.html index.html
[root@leaf html]# mv index.html index.html.source
[root@leaf html]# echo "<h1>Hello, I'm xpleaf.</h1>">index.html
[root@leaf html]# ls
50x.html index.html index.html.source
[root@leaf html]# cat index.html
<h1>Hello, I'm xpleaf.</h1>
这时在宿主机操作系统上访问http://10.0.0.101/
（1）Nginx安装
1.安装Nginx依赖函数库pcre、openssl-devel
[root@leaf ~]# yum install -y pcre pcre-devel openssl openssl-devel
......
[root@leaf ~]# rpm -q pcre pcre-devel openssl openssl-devel
pcre-7.8-7.el6.x86_64
pcre-devel-7.8-7.el6.x86_64
openssl-1.0.1e-48.el6_8.4.x86_64
openssl-devel-1.0.1e-48.el6_8.4.x86_64
2.下载安装Nginx
这里使用Nginx1.6.3，如下：
# 下载Nginx
[root@leaf ~]# yum install -y wget
[root@leaf ~]# mkdir tools
[root@leaf ~]# cd tools/
[root@leaf tools]# wget
[root@leaf tools]# ll

[root@leaf tools]# ll
总用量 792
drwxr-xr-x. 8 1001 1001 4096 4月 7 2015 nginx-1.6.3
-rw-r--r--. 1 root root 805253 4月 8 2015 nginx-1.6.3.tar.gz
# 指定编译参数
[root@leaf tools]# yum install -y gcc # 需要先安装gcc
[root@leaf tools]# mkdir /application # 作为Nginx的安装目录
[root@leaf tools]# useradd nginx -s /sbin/nologin -M
[root@leaf tools]# tail -1 /etc/passwd
nginx:x:500:500::/home/nginx:/sbin/nologin
[root@leaf tools]# cd nginx-1.6.3
[root@leaf nginx-1.6.3]# ./configure --user=nginx --group=nginx --prefix=/application/nginx-1.6.3/ --with-http_stub_status_module --with-http_ssl_module
[root@leaf nginx-1.6.3]# echo $? # 结果输出0则说明命令执行成功
# 编译
[root@leaf nginx-1.6.3]# make
[root@leaf nginx-1.6.3]# echo $?
# 安装
[root@leaf nginx-1.6.3]# make install
[root@leaf nginx-1.6.3]# echo $?
# 建立安装目录的软链接
[root@leaf nginx-1.6.3]# ln -s /application/nginx-1.6.3/ /application/nginx
[root@leaf nginx-1.6.3]# ls -l /application/
总用量 4
lrwxrwxrwx. 1 root root 25 3月 4 04:28 nginx -> /application/nginx-1.6.3/
drwxr-xr-x. 6 root root 4096 3月 4 04:27 nginx-1.6.3
（2）Nginx测试
1.启动Nginx
[root@leaf ~]# /application/nginx/sbin/nginx -t # 检查配置文件
nginx: the configuration file /application/nginx-1.6.3//conf/nginx.conf syntax is ok
nginx: configuration file /application/nginx-1.6.3//conf/nginx.conf test is successful
[root@leaf ~]# /application/nginx/sbin/nginx # 启动Nginx服务
2.CentOS上验证Nginx服务
[root@leaf ~]# netstat -lntup | grep 80
tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN 3929/nginx
[root@leaf ~]# curl localhost
<!DOCTYPE html>
<html>
<head>
<title>Welcome to nginx!</title>
<style>
body {

margin: 0 auto;
font-family: Tahoma, Verdana, Arial, sans-serif;
}
</style>
</head>
<body>
<h1>Welcome to nginx!</h1>
<p>If you see this page, the nginx web server is successfully installed and
working. Further configuration is required.</p>

Commercial support is available at
<a href="http://nginx.com/">nginx.com</a>.</p>
<p><em>Thank you for using nginx.</em></p>
</body>
</html>
3.宿主机上验证Nginx服务
在宿主机浏览器上输入CentOS主机的IP地址10.0.0.101，如下：
（3）域名配置
因为要搭建一个博客服务，所以这里配置的域名为blog.xpleaf.org，操作过程如下：
1.最小化配置文件
[root@leaf ~]# cd /application/nginx/conf/
[root@leaf conf]# wc -l nginx.conf
117 nginx.conf
[root@leaf conf]# wc -l nginx.conf.default
117 nginx.conf.default
[root@leaf conf]# egrep -v "#|^$" nginx.conf.default >nginx.conf
[root@leaf conf]# wc -l nginx.conf
22 nginx.conf
[root@leaf conf]# cat nginx.conf
worker_processes 1;
events {
worker_connections 1024;
}
http {
include mime.types;
default_type application/octet-stream;
sendfile on;
keepalive_timeout 65;
server {
listen 80;
server_name localhost;
location / {
root html;
index index.html index.htm;
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}
}
}
2.修改配置文件
修改nginx.conf，并且增加配置文件extra/blog.conf，如下：
[root@leaf conf]# cat nginx.conf
worker_processes 1;
events {
worker_connections 1024;
}
http {
include mime.types;
default_type application/octet-stream;
sendfile on;
keepalive_timeout 65;
include extra/blog.conf;
}
[root@leaf conf]# cat extra/blog.conf
server {
listen 80;
server_name blog.xpleaf.org;
location / {
root html/blog;
index index.html index.htm;
}
}
3.创建域名对应的站点目录及文件
[root@leaf conf]# cd ../html/
[root@leaf html]# mkdir blog
[root@leaf html]# echo "This page is: blog.xpleaf.org">blog/index.html
[root@leaf html]# cat blog/index.html
This page is: blog.xpleaf.org
4.重启Nginx服务
[root@leaf html]# /application/nginx/sbin/nginx -t
nginx: the configuration file /application/nginx-1.6.3//conf/nginx.conf syntax is ok
[root@leaf html]# /application/nginx/sbin/nginx -s reload # 平滑重启
5.CentOS 6.5上进行测试
先修改/etc/hosts文件：
[root@leaf html]# echo "127.0.0.1 blog.xpleaf.org" >>/etc/hosts
[root@leaf html]# tail -1 /etc/hosts
127.0.0.1 blog.xpleaf.org
再使用命令测试：
[root@leaf html]# curl blog.xpleaf.org
This page is: blog.xpleaf.org
[root@leaf html]# wget blog.xpleaf.org
--2017-03-04 04:58:42-- http://blog.xpleaf.org/ 正在解析主机 blog.xpleaf.org... 127.0.0.1
正在连接 blog.xpleaf.org|127.0.0.1|:80... 已连接。
已发出 HTTP 请求，正在等待回应... 200 OK
长度：30 [text/html]
正在保存至: “index.html.1”
100%[====================================>] 30 --.-K/s in 0s
2017-03-04 04:58:42 (2.14 MB/s) - 已保存 “index.html.1” [30/30])
6.宿主机Windows 7上进行测试
同样是先修改hosts文件，Windows 7的hosts文件在C:\Windows\System32\drivers\etc，同样添加下面一行：
1
10.0.0.101 blog.xpleaf.org
使用浏览器访问blog.xpleaf.org，如下：
3.LNMP环境搭建：MySQL安装与基本安全优化
这里采用二进制安装的方式来安装MySQL，安装的版本为：MySQL Server 5.5.54，可以在https://dev.mysql.com/downloads/mysql/5.5.html#downloads中下载。
MySQL安装完成后会做一些基本的安全优化。
（1）MySQL安装
1.创建MySQL用户的账号
[root@leaf ~]# groupadd mysql
[root@leaf ~]# useradd -s /sbin/nologin -g mysql -M mysql
[root@leaf ~]# tail -1 /etc/passwd
mysql:x:501:501::/home/mysql:/sbin/nologin
2.下载MySQL
可以使用wget来进行安装，也可以先下载到Windows 7上，然后使用SecureCRT，在CentOS上使用rz命令（需要使用yum install -y lrzsz命令安装）上传到我们的CentOS上，其实不管哪一种方式，只要有方式获取到该安装包就可以了，下面使用的是wget获取安装包的方式：
[root@leaf tools]# wget
[root@leaf tools]# ls -l mysql-5.5.54-linux2.6-x86_64.tar.gz
-rw-r--r--. 1 root root 185911232 3月 3 13:34 mysql-5.5.54-linux2.6-x86_64.tar.gz
3.解压并移到指定目录
[root@leaf tools]# tar xf mysql-5.5.54-linux2.6-x86_64.tar.gz
[root@leaf tools]# mv mysql-5.5.54-linux2.6-x86_64 /application/mysql-5.5.54
[root@leaf tools]# ln -s /application/mysql-5.5.54/ /application/mysql
[root@leaf tools]# ls -l /application/
总用量 8
lrwxrwxrwx. 1 root root 26 3月 4 06:43 mysql -> /application/mysql-5.5.54/
drwxr-xr-x. 13 root root 4096 3月 4 06:42 mysql-5.5.54
lrwxrwxrwx. 1 root root 25 3月 4 04:28 nginx -> /application/nginx-1.6.3/
drwxr-xr-x. 11 root root 4096 3月 4 04:30 nginx-1.6.3
4.初始化MySQL配置文件
[root@leaf mysql]# cp support-files/my-small.cnf /etc/my.cnf
cp：是否覆盖"/etc/my.cnf"？ y
5.初始化MySQL数据库文件
[root@leaf mysql]# mkdir -p /application/mysql/data/
[root@leaf mysql]# chown -R mysql.mysql /application/mysql
[root@leaf mysql]# yum install -y libaio # 安装MySQL依赖函数库，否则下面的初始化会失败
[root@leaf mysql]# /application/mysql/scripts/mysql_install_db --basedir=/application/mysql --datadir=/application/mysql/data --user=mysql
......
# 输出结果可以看到两个OK，即说明初始化成功
[root@leaf mysql]# echo $? # 或者通过该命令，输出为0，即说明上一个步骤的命令执行成功
0
# 上面之后可以看到/application/mysql/data/目录下生成的数据库文件
6.配置并启动MySQL数据库
#（1）设置MySQL启动脚本
[root@leaf mysql]# cp support-files/mysql.server /etc/init.d/mysqld
[root@leaf mysql]# chmod +x /etc/init.d/mysqld
[root@leaf mysql]# ls -l /etc/init.d/mysqld
-rwxr-xr-x. 1 root root 10875 3月 4 06:56 /etc/init.d/mysqld
#（2）替换启动脚本中MySQL默认的安装路径/usr/local/mysql
[root@leaf mysql]# sed -i 's#/usr/local/mysql#/application/mysql#g' /application/mysql/bin/mysqld_safe /etc/init.d/mysqld
#（3）启动MySQL数据库
[root@leaf mysql]# /etc/init.d/mysqld start
Starting MySQL.Logging to '/application/mysql/data/leaf.err'.
... SUCCESS!
#（4）检查MySQL数据库是否启动
[root@leaf mysql]# netstat -lntup | grep mysql
tcp 0 0 0.0.0.0:3306 0.0.0.0:* LISTEN 4400/mysqld
#（5）查看日志
[root@leaf mysql]# tail -10 /application/mysql/data/leaf.err

#（6）设置MySQL开机启动
[root@leaf mysql]# chkconfig --add mysqld
[root@leaf mysql]# chkconfig mysqld on
[root@leaf mysql]# chkconfig --list mysqld
mysqld 0:关闭 1:关闭 2:启用 3:启用 4:启用 5:启用 6:关闭
#（7）配置mysql命令的全局使用路径（注意这里配置的是命令，前面配置的只是启动脚本）
[root@leaf mysql]# echo 'export PATH=/application/mysql/bin:$PATH' >>/etc/profile
[root@leaf mysql]# source /etc/profile
[root@leaf mysql]# echo $PATH
/application/mysql/bin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin
#（8）登陆MySQL测试
[root@leaf mysql]# mysql

（2）MySQL基本安全优化
1.为root用户设置密码
1
[root@leaf mysql]# mysqladmin -u root password '123456'
2.清理无用的MySQL用户及数据库
[root@leaf mysql]# mysql -u root -p
Enter password:

到此为此，MySQL也安装完成了！
4.LNMP环境搭建：PHP（FastCGI方式）安装、配置与启动
（1）安装PHP依赖函数库
1.安装lib库
需要安装的lib库如下：
zlib-devel libxml2-devel libjpeg-devel libjpeg-turbo-devel libiconv-devel
freetype-devel libpng-devel gd-devel libcurl-devel libxslt-devel
其中除了libiconv库外，其他都可以通过yum的方式进行安装，安装如下：
# 使用yum安装除libiconv-devel之外的其它lib库
[root@leaf mysql]# yum install -y zlib-devel libxml2-devel libjpeg-devel libjpeg-turbo-devel libiconv-devel freetype-devel libpng-devel gd-devel libcurl-devel libxslt-devel
# 编译安装libiconv-devel
[root@leaf tools]# wget
[root@leaf tools]# tar zxf libiconv-1.14.tar.gz
[root@leaf tools]# cd libiconv-1.14
[root@leaf libiconv-1.14]# ./configure --prefix=/usr/local/libiconv
[root@leaf libiconv-1.14]# make
[root@leaf libiconv-1.14]# make install
2.安装libmcrypt库
[root@leaf ~]# wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-6.repo [root@leaf ~]# yum install -y libmcrypt-devel
3.安装mhash加密扩展库
[root@leaf ~]# yum install -y mhash
4.安装mcrypt加密扩展库
[root@leaf ~]# yum install -y mcrypt
（2）安装PHP
使用的PHP版本号为5.3.27，如下：
1.下载PHP安装包
[root@leaf tools]# wget http://cn2.php.net/get/php-5.3.27.tar.gz/from/this/mirror [root@leaf tools]# mv mirror php-5.3.27.tar.gz
[root@leaf tools]# ls -l php-5.3.27.tar.gz
-rw-r--r--. 1 root root 15008639 1月 21 2015 php-5.3.27.tar.gz
2.解压缩
[root@leaf tools]# tar zxf php-5.3.27.tar.gz
[root@leaf tools]# cd php-5.3.27
[root@leaf php-5.3.27]# pwd
/root/tools/php-5.3.27
3.配置PHP的安装参数
配置项非常多，如下：
./configure \
--prefix=/application/php5.3.27 \
--with-mysql=/application/mysql \
--with-iconv-dir=/usr/local/libiconv \
--with-freetype-dir \
--with-jpeg-dir \
--with-png-dir \
--with-zlib \
--with-libxml-dir=/usr \
--enable-xml \
--disable-rpath \
--enable-safe-mode \
--enable-bcmath \
--enable-shmop \
--enable-sysvsem \
--enable-inline-optimization \
--with-curl \
--with-curlwrappers \
--enable-mbregex \
--enable-fpm \
--enable-mbstring \
--with-mcrypt \
--with-gd \
--enable-gd-native-ttf \
--with-openssl \
--with-mhash \
--enable-pcntl \
--enable-sockets \
--with-xmlrpc \
--enable-zip \
--enable-soap \
--enable-short-tags \
--enable-zend-multibyte \
--enable-static \
--with-xsl \
--with-fpm-user=nginx \
--with-fpm-group=nginx \
--enable-ftp
可以将其直接复制到命令行进行配置，这样就可以减少出错的概率：
[root@leaf php-5.3.27]# ./configure \
> --prefix=/application/php5.3.27 \
> --with-mysql=/application/mysql \
> --with-iconv-dir=/usr/local/libiconv \
> --with-freetype-dir \
> --with-jpeg-dir \
> --with-png-dir \
> --with-zlib \
> --with-libxml-dir=/usr \
> --enable-xml \
> --disable-rpath \
> --enable-safe-mode \
> --enable-bcmath \
> --enable-shmop \
> --enable-sysvsem \
> --enable-inline-optimization \
> --with-curl \
> --with-curlwrappers \
> --enable-mbregex \
> --enable-fpm \
> --enable-mbstring \
> --with-mcrypt \
> --with-gd \
> --enable-gd-native-ttf \
> --with-openssl \
> --with-mhash \
> --enable-pcntl \
> --enable-sockets \
> --with-xmlrpc \
> --enable-zip \
> --enable-soap \
> --enable-short-tags \
> --enable-zend-multibyte \
> --enable-static \
> --with-xsl \
> --with-fpm-user=nginx \
> --with-fpm-group=nginx \
> --enable-ftp

4.编译PHP
[root@leaf php-5.3.27]# ln -s /application/mysql/lib/libmysqlclient.so.18
libmysqlclient.so.18 libmysqlclient.so.18.0.0
[root@leaf php-5.3.27]# ln -s /application/mysql/lib/libmysqlclient.so.18 /usr/lib64/
[root@leaf php-5.3.27]# touch ext/phar/phar.phar
[root@leaf php-5.3.27]# make
......
[root@leaf php-5.3.27]# echo $?
0
5.安装PHP
[root@leaf php-5.3.27]# make install
/root/tools/php-5.3.27/build/shtool install -c ext/phar/phar.phar /application/php5.3.27/bin
ln -s -f /application/php5.3.27/bin/phar.phar /application/php5.3.27/bin/phar
Installing PDO headers: /application/php5.3.27/include/php/ext/pdo/
......
[root@leaf php-5.3.27]# echo $?
0
（3）配置与启动PHP
1.设置PHP安装目录软链接
[root@leaf php-5.3.27]# ln -s /application/php5.3.27/ /application/php
[root@leaf php-5.3.27]# ls -l /application/php
lrwxrwxrwx. 1 root root 23 3月 4 08:59 /application/php -> /application/php5.3.27/
2.拷贝PHP配置文件到PHP默认目录
[root@leaf php-5.3.27]# cp php.ini-production /application/php/lib/php.ini
[root@leaf php-5.3.27]# ls -l /application/php/lib/php.ini
-rw-r--r--. 1 root root 69627 3月 4 09:00 /application/php/lib/php.ini
3.配置php-fpm.conf文件
[root@leaf php-5.3.27]# cd /application/php/etc/
[root@leaf etc]# ls
pear.conf php-fpm.conf.default
[root@leaf etc]# cp php-fpm.conf.default php-fpm.conf
4.启动PHP服务php-fpm
[root@leaf etc]# /application/php/sbin/php-fpm
5.检查启动进程与侦听端口号
[root@leaf etc]# ps -ef | grep php-fpm
root 129256 1 0 09:05 ? 00:00:00 php-fpm: master process (/application/php5.3.27/etc/php-fpm.conf)
nginx 129257 129256 0 09:05 ? 00:00:00 php-fpm: pool www
nginx 129258 129256 0 09:05 ? 00:00:00 php-fpm: pool www
root 129260 13743 0 09:06 pts/1 00:00:00 grep php-fpm
[root@leaf etc]# netstat -lntup | grep 9000
tcp 0 0 127.0.0.1:9000 0.0.0.0:* LISTEN 129256/php-fpm
至此，PHP也安装完成了！LNMP的各个组件都安装好了，下面就要对LNMP环境进行测试了。
5.LNMP环境测试
（1）配置Nginx支持PHP程序请求访问
1.查看当前Nginx配置
[root@leaf etc]# cd /application/nginx/conf/
[root@leaf conf]# cat nginx.conf
worker_processes 1;
events {
worker_connections 1024;
}
http {
include mime.types;
default_type application/octet-stream;
sendfile on;
keepalive_timeout 65;
include extra/blog.conf;
}
[root@leaf conf]# cat extra/blog.conf
server {
listen 80;
server_name blog.xpleaf.org;
location / {
root html/blog;
index index.html index.htm;
}
}
2.修改extra/blog.conf配置文件
[root@leaf conf]# cat extra/blog.conf
server {
listen 80;
server_name blog.xpleaf.org;
location / {
root html/blog;
index index.html index.htm;
}
location ~ .*\.(php|php5)?$ {
root html/blog;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
include fastcgi.conf;
}
}
3.检查并启动Nginx
[root@leaf conf]# /application/nginx/sbin/nginx -t
nginx: the configuration file /application/nginx-1.6.3//conf/nginx.conf syntax is ok
nginx: configuration file /application/nginx-1.6.3//conf/nginx.conf test is successful
[root@leaf conf]# /application/nginx/sbin/nginx -s reload
（2）测试LNMP环境是否生效
1.配置域名站点目录
[root@leaf conf]# cd /application/nginx/html/blog/
[root@leaf blog]# echo "<?php phpinfo(); ?>" >test_info.php
[root@leaf blog]# cat test_info.php
<?php phpinfo(); ?>
2.宿主机上在浏览器中输入地址http://blog.xpleaf.org/test_info.php进行访问
（3）测试PHP连接MySQL是否正常
1.编辑text_mysql.php
[root@leaf blog]# cat test_mysql.php
<?php
$link_id=mysql_connect('localhost', 'root', '123456');
if($link_id){
echo "mysql succesful by xpleaf !";
}else{
echo mysql_error();
}
?>
2.宿主机上在浏览器中输入地址http://blog.xpleaf.org/test_mysql.php进行访问
至此，LNMP环境搭建与测试完成了，下面就可以开始部署WordPress了！
6.部署WordPress
（1）MySQL数据库准备
1.登陆mysql
[root@leaf blog]# mysql -u root -p
Enter password:

4 rows in set (0.00 sec)
3.创建wordpress blog管理用户
mysql> grant all on wordpress.* to wordpress@'localhost' identified by '123456';
Query OK, 0 rows affected (0.08 sec)
mysql> show grants for wordpress@'localhost';
+------------------------------------------------------------------------------------------------------------------+
| Grants for wordpress@localhost |
+------------------------------------------------------------------------------------------------------------------+
| GRANT USAGE ON *.* TO 'wordpress'@'localhost' IDENTIFIED BY PASSWORD '*6BB4837EB74329105EE4568DDA7DC67ED2CA2AD9' |
| GRANT ALL PRIVILEGES ON `wordpress`.* TO 'wordpress'@'localhost' |
+------------------------------------------------------------------------------------------------------------------+
2 rows in set (0.00 sec)
4.刷新MySQL用户权限
mysql> flush privileges;
Query OK, 0 rows affected (0.31 sec)
5.检查MySQL登录用户
mysql> select user,host from mysql.user;
+-----------+-----------+
| user | host |
+-----------+-----------+
| root | 127.0.0.1 |
| root | localhost |
| wordpress | localhost |
+-----------+-----------+
3 rows in set (0.00 sec)
（2）Nginx配置准备
1.修改blog.conf配置文件
[root@leaf conf]# cat extra/blog.conf
server {
listen 80;
server_name blog.xpleaf.org;
location / {
root html/blog;
index index.php index.html index.htm;
}
location ~ .*\.(php|php5)?$ {
root html/blog;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
include fastcgi.conf;
}
}
# 相比前面的配置文件，只是在/下添加了index.php
# 不过需要注意的是，index.php一定要放在index关键字之后，
# 这样访问blog.xpleaf.org时，才会打开我们的WordPress页面
2.重启Nginx服务
[root@leaf conf]# /application/nginx/sbin/nginx -s reload
（3）配置WordPress
1.获取WordPress安装包
[root@leaf tools]# wget
[root@leaf tools]# ls -lh wordpress-4.7.2-zh_CN.tar.gz
-rw-r--r--. 1 root root 8.1M 1月 28 08:53 wordpress-4.7.2-zh_CN.tar.gz
2.解压缩与配置站点目录
[root@leaf tools]# cp wordpress-4.7.2-zh_CN.tar.gz /application/nginx/html/blog/
[root@leaf tools]# cd /application/nginx/html/blog/
[root@leaf blog]# tar zxf wordpress-4.7.2-zh_CN.tar.gz
[root@leaf blog]# ls
index.html test_mysql.php wordpress-4.7.2-zh_CN.tar.gz
test_info.php wordpress
[root@leaf blog]# rm -rf test_* wordpress-4.7.2-zh_CN.tar.gz # 删除无用的文件
[root@leaf blog]# ls
index.html wordpress
[root@leaf blog]# mv wordpress/* ./ # 将wordpress程序移到当前blog目录下
[root@leaf blog]# ls
index.html wp-admin wp-includes wp-signup.php
index.php wp-blog-header.php wp-links-opml.php wp-trackback.php
license.txt wp-comments-post.php wp-load.php xmlrpc.php
readme.html wp-config-sample.php wp-login.php
wordpress wp-content wp-mail.php
wp-activate.php wp-cron.php wp-settings.php
[root@leaf blog]# ls -l
总用量 196
-rw-r--r--. 1 root root 30 3月 4 04:54 index.html
-rw-r--r--. 1 nobody 65534 418 9月 25 2013 index.php
-rw-r--r--. 1 nobody 65534 19935 1月 3 02:51 license.txt
-rw-r--r--. 1 nobody 65534 6956 1月 28 08:53 readme.html
drwxr-xr-x. 2 nobody 65534 4096 3月 4 09:50 wordpress
......
3.对blog下所有文件授予nginx用户和组的权限
[root@leaf blog]# chown -R nginx.nginx ../blog/
[root@leaf blog]# ls -l
总用量 196
-rw-r--r--. 1 nginx nginx 30 3月 4 04:54 index.html
-rw-r--r--. 1 nginx nginx 418 9月 25 2013 index.php
-rw-r--r--. 1 nginx nginx 19935 1月 3 02:51 license.txt
-rw-r--r--. 1 nginx nginx 6956 1月 28 08:53 readme.html
drwxr-xr-x. 2 nginx nginx 4096 3月 4 09:50 wordpress
......
（4）安装WordPress
在宿主机浏览器上输入地址：http://blog.xpleaf.org，如下：
接下来的安装都是非常人性化的，点击“现在就开始”，出现下面的页面：
填好信息后，点击“提交”，如下：
点击“进行安装”，接下来就会让我们填写一些信息，如下：
点击“安装WordPress”，之后就会显示如下页面：
显示上面的页面，就说明我们的WordPress安装成功了！接下来就可以好好管理自己的个人WordPress博客站点了！
7.下一步要做什么
可以在云主机上，如腾讯云或者阿里云上搭建LNMP环境，再部署一个WordPress博客程序，为了达到域名访问的效果，可以购买一个域名，然后自己搭建DNS服务器，这会是非常不错的体验！
接下来就可以考虑对LNMP进行优化了。

www.youku.com www.letv.com
www.bird.org :所有资源（做链接），搜索功能 目的是扩大自己网站的影响和点击，让别人知道自己域名。
防止盗链
vaild_referers (有效的 允许链接)
if 拒绝的
实验操作：
location ~*\. (pdf|jpg|mp3|png|flv) ${

使用Nginx可以配置基于域名的虚拟主机、基于端口的虚拟主机和基于端口的虚拟主机，比较常用的是基于域名的虚拟主机，这里要做的配置是基于域名的虚拟主机，并且是配置多个基于域名的虚拟主机。
2.配置一个基于域名的虚拟主机与测试
先启动Nginx，验证服务是否正常：
[root@leaf ~]# /application/nginx/sbin/nginx
[root@leaf ~]# netstat -lnp | grep 80
tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN 6881/nginx
unix 2 [ ACC ] STREAM LISTENING 9180 1/init @/com/ubuntu/upstart
[root@leaf ~]# curl localhost
<h1>Hello, I'm xpleaf.</h1>
[root@leaf ~]# LANG=en
[root@leaf ~]# wget localhost
--2017-02-24 13:33:43-- http://localhost/ Resolving localhost... ::1, 127.0.0.1
Connecting to localhost|::1|:80... failed: Connection refused.
Connecting to localhost|127.0.0.1|:80... connected.
HTTP request sent, awaiting response... 200 OK
Length: 28 [text/html]
Saving to: `index.html.1'
100%[======================================>] 28 --.-K/s in 0s
2017-02-24 13:33:43 (1.87 MB/s) - `index.html.1' saved [28/28]
从上面的输出可以看到，此时Nginx是可以正常运行和提供服务的。
（1）实验准备：最小化Nginx的主配置文件nginx.conf
Nginx的配置文件在安装目录下的conf目录中：
[root@leaf ~]# tree /application/nginx
/application/nginx
|-- client_body_temp
|-- conf
| |-- fastcgi.conf
| |-- fastcgi.conf.default
| |-- fastcgi_params
| |-- fastcgi_params.default
| |-- koi-utf
| |-- koi-win
| |-- mime.types
| |-- mime.types.default
| |-- nginx.conf
| |-- nginx.conf.default
| |-- scgi_params
| |-- scgi_params.default
| |-- uwsgi_params
| |-- uwsgi_params.default
| `-- win-utf
|-- fastcgi_temp
|-- html
| |-- 50x.html
| |-- index.html
| `-- index.html.source
|-- logs
| |-- access.log
| |-- error.log
| `-- nginx.pid
|-- proxy_temp
|-- sbin
| `-- nginx
|-- scgi_temp
`-- uwsgi_temp
nginx.conf便是主配置文件，nginx.conf.default则是它的备份，该配置文件有数百行：
1
2
[root@leaf conf]# wc -l nginx.conf
117 nginx.conf
为了学习的方便，可以考虑将其注释内容去掉：
[root@leaf conf]# egrep -v "#|^$" nginx.conf.default >nginx.conf
[root@leaf conf]# cat nginx.conf
worker_processes 1;
events {
worker_connections 1024;
}
http {
include mime.types;
default_type application/octet-stream;
sendfile on;
keepalive_timeout 65;
server {
listen 80;
server_name localhost;
location / {
root html;
index index.html index.htm;
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}
}
}
[root@leaf conf]# wc -l nginx.conf
22 nginx.conf
去掉了注释和空白行后只有22行，就很方便我们待会做实验时进行配置了。
（2）修改配置文件
假设我们的Nginx为站点www.xpleaf.cn服务，则可以将主配置文件修改为如下：
[root@leaf conf]# cat nginx.conf
worker_processes 1;
events {
worker_connections 1024;
}
http {
include mime.types;
default_type application/octet-stream;
sendfile on;
keepalive_timeout 65;
server {
listen 80;
server_name www.xpleaf.com;
location / {
root html/www;
index index.html index.htm;
}
}
}
主要是修改了第12行和第14行，其中第14行说明该站点的根目录的html文件在html/www/目录中。
（3）创建域名对应的站点目录及文件
[root@leaf nginx]# cd html/
[root@leaf html]# mkdir www
[root@leaf html]# echo "This page is: www.xpleaf.cn">www/index.html
[root@leaf html]# cat www/index.html
This page is: www.xpleaf.cn
（4）重新启动Nginx服务
[root@leaf html]# /application/nginx/sbin/nginx -t # 检查Nginx配置语法
nginx: the configuration file /application/nginx-1.6.3//conf/nginx.conf syntax is ok
nginx: configuration file /application/nginx-1.6.3//conf/nginx.conf test is successful
[root@leaf html]# /application/nginx/sbin/nginx -s reload # 优雅重启Nginx
（5）在CentOS 6.5上进行测试
因为上面我们设置的域名www.xpleaf.cn实际是可能不存在，但为了达到测试的目的，即当访问www.xpleaf.cn时，能够解析到我们CentOS上的IP地址，从而可以访问其上面的Nginx服务，达到访问Nginx虚拟主机的目的，所以在CentOS上进行测试时，我们需要修改/etc/hosts文件，让www.xpleaf.cn解析为CentOS的IP地址：
[root@leaf html]# echo "127.0.0.1 www.xpleaf.cn" >>/etc/hosts
[root@leaf html]# tail -1 /etc/hosts
127.0.0.1 www.xpleaf.cn
此时，在CentOS上使用curl命令和wget命令来访问www.xpleaf.cn，查看测试结果：
[root@leaf html]# curl www.xpleaf.cn
This page is: www.xpleaf.cn
[root@leaf html]# wget www.xpleaf.cn
--2017-02-24 13:58:29-- http://www.xpleaf.cn/ Resolving www.xpleaf.cn... 127.0.0.1
Connecting to www.xpleaf.cn|127.0.0.1|:80... connected.
HTTP request sent, awaiting response... 200 OK
Length: 28 [text/html]
Saving to: `index.html.1'
100%[======================================>] 28 --.-K/s in 0s
2017-02-24 13:58:29 (2.24 MB/s) - `index.html.1' saved [28/28]
从输出结果可以知道，此时Nginx成功地为域名为www.xpleaf.cn的虚拟主机提供了服务。
（6）在Windows 7主机上进行测试
为了达到前面说的目的，在Windows操作系统上同样需要修改hosts文件，Windows 7的hosts文件在C:\Windows\System32\drivers\etc，同样添加下面一行：
1
10.0.0.101 www.xpleaf.cn
这时在浏览器中输入地址www.xpleaf.cn，查看返回的结果：
wKiom1ixs6jzW6yTAAAjHHKgIE8656.png
可以看到，可以正常访问。
3.配置多个基于域名的虚拟主机与测试
上面的实验中只有一个站点www.xpleaf.cn，假如还有两个站点bbs.xpleaf.cn和log.xpleaf.cn，
同样需要Nginx来提供服务，这时就需要配置多个基于域名的虚拟主机了，不过有了上面的基础后，下面
的操作就会容易很多，因为思路都是一样的。
（1）修改主配置文件nginx.conf
在前面的基础上，修改为如下：
[root@leaf conf]# cat nginx.conf
worker_processes 1;
events {
worker_connections 1024;
}
http {
include mime.types;
default_type application/octet-stream;
sendfile on;
keepalive_timeout 65;
server {
listen 80;
server_name www.xpleaf.com;
location / {
root html/www;
index index.html index.htm;
}
}
server {
listen 80;
server_name bbs.xpleaf.com;
location / {
root html/bbs;
index index.html index.htm;
}
}
server {
listen 80;
server_name blog.xpleaf.com;
location / {
root html/blog;
index index.html index.htm;
}
}
}
（2）创建域名对应的站点目录及文件
[root@leaf html]# mkdir bbs
[root@leaf html]# echo "This page is: bbs.xpleaf.cn" >bbs/index.html
[root@leaf html]# mkdir blog
[root@leaf html]# echo "This page is: blog.xpleaf.cn" >blog/index.html
[root@leaf html]# cat bbs/index.html blog/index.html
This page is: bbs.xpleaf.cn
This page is: blog.xpleaf.cn
（3）重新启动Nginx服务
[root@leaf html]# /application/nginx/sbin/nginx -t # 检查Nginx配置语法
nginx: the configuration file /application/nginx-1.6.3//conf/nginx.conf syntax is ok
nginx: configuration file /application/nginx-1.6.3//conf/nginx.conf test is successful
[root@leaf html]# /application/nginx/sbin/nginx -s reload # 优雅重启Nginx
（4）在CentOS 6.5上进行测试
在原来基础上，修改/etc/hosts文件，在127.0.0.1地址后添加bbs.xpleaf.cn和blog.xpleaf.cn两个域名：
[root@leaf html]# tail -1 /etc/hosts
127.0.0.1 www.xpleaf.cn bbs.xpleaf.cn blog.xpleaf.cn
使用curl命令和wget命令进行测试：
[root@leaf html]# curl bbs.xpleaf.cn
This page is: www.xpleaf.cn
[root@leaf html]# curl blog.xpleaf.cn
This page is: www.xpleaf.cn

从上面结果可以知道，Nginx为各个虚拟主机正常提供服务。
（5）在Windows 7主机上进行测试
在原来基础上，修改hosts文件，如下：
1
10.0.0.101 www.xpleaf.cn bbs.xpleaf.cn blog.xpleaf.cn
在浏览器上分别访问各个域名，查看其返回结果：
访问www.xpleaf.cn:
访问bbs.xpleaf.cn:
访问blog.xpleaf.cn:
可以看到访问每个域名都返回了期待的页面，说明测试成功！
6.进阶：Nginx虚拟主机的别名配置
所以虚拟主机别名，就是为虚拟主机设置除了主域名以外的一个或多个域名名字，这样就能实现用户访问的多个域名对应同一个虚拟主机网站的功能。
以www.xpleaf.cn为例，希望添加一个别名xpleaf.cn，这样当访问xpleaf.cn时，和访问www.xpleaf.cn得到的结果是一样的。
其实配置的思路非常简单，只需要在上面nginx.conf配置文件中www.xpleaf.cn的server域中再添加一个xpleaf.cn的域名就可以了，如下：
server {
listen 80;
server_name www.xpleaf.com xpleaf.cn;
location / {
root html/www;
index index.html index.htm;
}
}
测试的话依然按照前面的方法进行，即先检查Nginx配置文件、平滑重启Nginx服务、配置hosts文件，最后通过命令行或浏览器的方式进行验证，因为跟前面是一样的，所以这里就不展开了。
5.下一步要做什么
可以考虑配置与测试基于端口的虚拟主机和基于IP地址的虚拟主机，其实只要把上面的弄清楚了，再做这些配置就会容易很多了。
