nginx动静分离
-
实验拓扑：
-
实验环境：
Nginx分发器 192.168.42.175 xuegod175.cn
Web1服务器 192.168.42.176 xuegod176.cn 作为image图片web服务器
Web2服务器 192.168.42.177 xuegod177.cn 作为php web服务器
实验注意：关闭iptables selinux 配置好hosts 文件，两台web服务器这里均使用了nginx

配置测试文件（支持图片）
[[email protected] html]# ls
50x.html a abc.jpg bin binbin.jpeg index.html index.htmlbak nginx.conf
从客户端进行访问测试
说明nginx web1服务已经成功支持访问图片
通过分发器进行访问测试（图片文件是web1服务器的）
说明nginx读写分离已经成功 nginx分发器可以正常的读取web1服务器的图片文件
Web2服务器配置
为了使nginx能够支持访问php环境，这里特意安装了lnmp环境
安装mysql
[[email protected] ]yum -y install mysql mysql-server mysql-devel
[[email protected] ] /etc/init.d/mysqld start
安装php
[[email protected] ]yum install php php-mysql php-common php-gd php-mbstring php-mcrypt php-devel php-xml –y
[[email protected] ]yum install php-fpm –y
[[email protected] ]/etc/init.d/php-fpm start
[[email protected] html]# ls
50x.html index.html index.html.bak index.php
[[email protected] html]# cat index.php 创建测试文件
<?php phpinfo(); ?>

Web2访问测试：
说明177web 已经支持php 可以正常使用访问。
动静分离访问进行测试
访问nginx分发器 index.php(这个文件是177web2服务器上的)，nginx分发器可以正常读取172 web2服务器的php 文件，说明读写分离已经成功。
