2. # yum groupinstall 'Development Tools' 'Development Libraries' -y

3.# groupadd nginx

# useradd -g nginx -s /bin/false -M nginx

4. # tar xvf nginx-0.8.20.tar.gz

# cd nginx-0.8.20

./configure \

--prefix=<path> - The path relative to which all other Nginx paths will resolve. If not

specified, defaults to /usr/local/nginx.

--sbin-path=<path> - The path to the nginx executable. Only used for installation. If not

specified defaults to <prefix>/sbin/nginx.

esac

6.

# chmod +x /etc/init.d/nginxd

# chkconfig --add nginxd

# chkconfig nginxd on

# service nginxd start

7. 测试 http://192.168.0.37/

可以看到 Welcome to nginx!

修改路径

8. # mkdir -pv /www/htdocs

9. # vim /etc/nginx/nginx.conf

修改

user nginx

location / {

root /www/htdocs;

index index.html index.htm;

}

10. echo '<h1>My nginx</h1>' > /www/htdocs/index.html

11. service nginxd restart

12. 测试 http://192.168.0.37/

二、 安装mysql

1. tar xvf mysql-5.1.45-linux-i686-glibc23.tar.gz -C /usr/local/

2. # cd /usr/local/

# ln -sv mysql-5.1.45-linux-i686-glibc23/ mysql

3. 添加用户和组

# groupadd mysql

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

4.

# cd mysql

# chown mysql:mysql . -R

# scripts/mysql_install_db --user=mysql (初始化)

# chown -R root .

# chown -R mysql data/

5.

# bin/mysqld_safe --user=mysql

# netstat -tnlp （查看3306端口是否打开）

6. 加载mysql的库文件

# vim /etc/ld.so.conf.d/mysql.conf

添加库文件路径 “/usr/local/mysql/lib”

# ldconfig -v （加载 ）

7.

加载开发文件

# ln -sv /usr/local/mysql/include/ /usr/include/mysql

8.

启动文件

# cp support-files/mysql.server /etc/init.d/mysqld

# chkconfig --add mysqld （加到自动启动队列）

# chkconfig mysqld on （开机自动启动）

9. 调整配置文件

# cp support-files/my-large.cnf /etc/my.cnf

10. 验证 重启服务

service mysqld restart

11.

# vim /etc/profile

找到 ‘export PATH USER LOGNAME MAIL HOSTNAME HISTSIZE INPUTRC’

在前一行添加

PATH=$PATH:/usr/local/mysql/bin

# . /etc/profile

# mysql (即可进入mysql的命令行)

三、 安装php

1. 安装libevent (调度文件时依赖于这个库文件)

# tar xvf libevent-1.4.14b-stable.tar.gz

# cd libevent-1.4.14b-stable

# ./configure

# make && make install

2 安装 libiconv（建立会话是用来实现网络解析方式的一种组件，有利于加速网络访问）

# tar xvf libiconv-1.13.1.tar.gz

# cd libiconv-1.13.1

# ./configure

# make && make install

3. 安装php

# tar xvf php-5.3.3.tar.bz2

# cd php-5.3.3

# ./configure --prefix=/usr/local/php --with-mysql=/usr/local/mysql --with-openssl --

enable-fpm --with-libevent-dir=/usr/local --with-mysqli=/usr/local/mysql/bin/mysql_config --

enable-mbstring --with-freetype-dir --with-jpeg-dir --with-png-dir --with-zlib --with-libxml

-dir=/usr --enable-xml --with-iconv-dir=/usr/local

# make ZEND_EXTRA_LIBS='-liconv'

# make install

# cp php.ini-production /usr/local/php/etc/php.ini

# cd /usr/local/php/etc/

# cp php-fpm.conf.default php-fpm.conf

# vim php-fpm.conf

启用

pm.start_servers = 20

pm.min_spare_servers = 5

pm.max_spare_servers = 35

pm.max_requests = 500

启动服务：

# /usr/local/php/sbin/php-fpm

查看9000端口是否打开

设置开机启动

# vim /etc/rc.d/rc.local

加入 /usr/local/php/sbin/php-fpm

四、配置

1、 编辑主配置文件

# vim /etc/nginx/nginx.conf

修改一下两段内容为：

location / {

root /www/htdocs;

index index.php index.html index.htm;

}

location ~ \.php$ {

root /www/htdocs;

fastcgi_pass 127.0.0.1:9000;

fastcgi_index index.php;

# fastcgi_param SCRIPT_FILENAME /scripts$fastcgi_script_name;

include fastcgi_params;

}

# vim /etc/nginx/fastcgi_params

修改为：

fastcgi_param GATEWAY_INTERFACE CGI/1.1;

fastcgi_param SERVER_SOFTWARE nginx;

fastcgi_param QUERY_STRING $query_string;

fastcgi_param REQUEST_METHOD $request_method;

fastcgi_param CONTENT_TYPE $content_type;

fastcgi_param CONTENT_LENGTH $content_length;

fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;

fastcgi_param SCRIPT_NAME $fastcgi_script_name;

fastcgi_param REQUEST_URI $request_uri;

fastcgi_param DOCUMENT_URI $document_uri;

fastcgi_param DOCUMENT_ROOT $document_root;

fastcgi_param SERVER_PROTOCOL $server_protocol;

fastcgi_param REMOTE_ADDR $remote_addr;

fastcgi_param REMOTE_PORT $remote_port;

fastcgi_param SERVER_ADDR $server_addr;

fastcgi_param SERVER_PORT $server_port;

fastcgi_param SERVER_NAME $server_name;

2. # service nginxd restart

# vim /www/htdocs/index.php

<?php

phpinfo()

?>

测试： http://192.168.0.37/
