lnmp搭建wordpress实例（一）

申明：此文档目的是搭建基础的lnmp环境，不做nginx、php-fpm过多优化说明。wordpress安装参考官方文档即可，过程介绍比较粗略，为的是验证lnmp环境正常，同时不介绍wordpress个性化设置。
nginx+mysql+php+memcache+Zend Optimizer+eaccelerator

zend optimizer 是一个代码优化的模块，可以调优php代码，实现的原理是对那些在被最终执行之前由运行编译器(Run-Time Compiler)产生的代码进行优化。代码性能可以提高40%到100%，

eAccelerator 是一个将编译之后的php代码缓存在share memory中的模块。通过访问共享内存可以得到编译后的代码并直接执行用以提高效率，这个对于php的执行效率的提高还是很大的。

一、环境准备：

1、系统约定：

系统：centos5.6 32Bit
软件包存放：/usr/local/src
apache网站根目录：/home/wwwroot/
mysql数据目录：/data/mysql
vhost日志根目录：/home/wwwlogs/
apache运行账户：www
mysql运行账户：www
服务器ip：172.16.57.10
domainname:www.iceman10.com

wget -c http://cn.wordpress.org/wordpress-3.3.1-zh_CN.tar.gz
2、yum 安装开发包

yum -y install libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel libxml2 libxml2-devel zlib zlib-devel glibc glibc-devel glib2 glib2-devel ncurses ncurses-devel curl curl-devel openssl openssl-devel openldap openldap-devel gd gd-devel libmcrypt libmcrypt-devel libtool gcc gcc-c++

gd库使用yum安装

二、编译安装NMP环境

2.1、创建Nginx账户及目录

创建nginx用户
groupadd www
useradd -s /sbin/nologin -g www www

创建nginx数据、日志目录
mkdir -p /home/wwwroot
mkdir -p /home/wwwlogs
chown -R www:www wwwlogs wwwroot

2.2、安装pcre

安装pcre 是为了nginx支持rewrite模块

tar zxvf pcre-8.12.tar.gz
cd pcre-8.12/
./configure
make && make install

2.3、安装、配置nginx
tar zxvf nginx-1.0.10.tar.gz
cd nginx-1.0.10/
./configure --user=www --group=www --prefix=/usr/local/nginx --with-http_stub_status_module --with-http_ssl_module --with-http_gzip_static_module
make && make install

nginx.conf配置
/usr/local/nginx/conf/nginx.conf
user www www;
worker_processes 1;
error_log /home/wwwlogs/nginx_error.log crit;
pid /usr/local/nginx/logs/nginx.pid;
#Specifies the value for maximum file descriptors that can be opened by this process.
worker_rlimit_nofile 51200;
events
{
use epoll;
worker_connections 51200;
}
http
{
include mime.types;
default_type application/octet-stream;
server_names_hash_bucket_size 128;
client_header_buffer_size 32k;
large_client_header_buffers 4 32k;
client_max_body_size 50m;
sendfile on;
tcp_nopush on;
keepalive_timeout 60;
tcp_nodelay on;
fastcgi_connect_timeout 300;
fastcgi_send_timeout 300;
fastcgi_read_timeout 300;
fastcgi_buffer_size 64k;
fastcgi_buffers 4 64k;
fastcgi_busy_buffers_size 128k;
fastcgi_temp_file_write_size 256k;
gzip on;
gzip_min_length 1k;
gzip_buffers 4 16k;
gzip_http_version 1.0;
gzip_comp_level 2;
gzip_types text/plain application/x-javascript text/css application/xml;
gzip_vary on;
#limit_zone crawler $binary_remote_addr 10m;
include vhost/*.conf;
}

创建 vhost/www.iceman10.com.conf

server
{
listen 80;
server_name www.iceman.com bbs.iceman.com;
index index.html index.htm index.php default.html default.htm default.php;
root /home/wwwroot/www.iceman10.com/htdocs;
location ~ .*\.(php|php5)?$
{
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
include fastcgi.conf;
}
location ~ .*\.(gif|jpg|jpeg|png|bmp|swf)$
{
expires 30d;
}
location ~ .*\.(js|css)?$
{
#expires 12h;
access_log off;
}
log_format www.iceman.com '$remote_addr - $remote_user [$time_local] $request '
'$status $body_bytes_sent $http_referer '
'$http_user_agent $http_x_forwarded_for';
access_log /home/wwwlogs/www.iceman.com.log www.iceman.com;
}

/usr/local/nginx/sbin/nginx –t \\检测nginx.conf配置文件

2.4、创建mysql运行账户及目录

groupadd mysql
useradd -s /sbin/nologin -M -g mysql mysql

mkdir -p /data/mysql
chown -R mysql:mysql /data/mysql/

2.5、mysql 编译安装
tar xzvf mysql-5.1.60.tar.gz
cd mysql-5.1.60
./configure --prefix=/usr/local/mysql --with-extra-charsets=all --with-charset=utf8 --enable-thread-safe-client --with-big-tables --enable-assembler --with-mysqld-ldflags=-all-static --with-plugins=all
make && make install

cd /usr/local/mysql/
chown -R mysql:mysql .
/usr/local/mysql/bin/mysql_install_db --user=mysql
chown -R root .
chown -R mysql var
cp /usr/local/mysql/share/mysql/my-medium.cnf /etc/my.cnf
cp /usr/local/mysql/share/mysql/mysql.server /etc/init.d/mysql

修改my.cnf
datadir = /data/mysql
sed -i "s/skip-locking/skip-external-locking/g" /etc/my.cnf

/usr/local/mysql/bin/mysql_install_db --user=mysql
/usr/local/mysql/bin/mysqld_safe --user=mysql &

2.6、php编译安装

tar zxvf php-5.2.17.tar.gz
gzip -cd php-5.2.17-fpm-0.5.14.diff.gz | patch -d php-5.2.17 -p1
cd php-5.2.17/
./configure --prefix=/usr/local/php5 --with-config-file-path=/usr/local/php5/etc --with-mysql=/usr/local/mysql --enable-fastcgi --enable-fpm --enable-discard-path --enable-force-cgi-redirect --with-libxml-dir --with-xmlrpc --with-gd --with-iconv-dir --with-freetype-dir --with-jpeg-dir --with-png-dir --with-curl --with-curlwrappers --enable-mbstring --with-mcrypt --enable-soap --enable-ftp

make
make install

cp php.ini-dist /usr/local/php5/etc/php.ini

2.7、php-fpm配置

/usr/local/php5/etc

Unix user of
processes
<value
name="user">www</value>

Unix group of
processes
<value
name="group">www</value>

2.8、lnmp验证
/usr/local/nginx/sbin/nginx 启动nginx服务
/usr/local/php5/sbin/php-fpm restart 启动php-fpm

创建 /home/wwwroot/www.iceman10.com/htdocs/phinfo.php

[root@demo10 htdocs]# cat phpinfo.php
<?
phpinfo();
?>
