反向代理（Reverse Proxy）方式是指以代理服务器来接受internet上的连接请求，然后将请求转发给内部网络上的服务器，并将从服务器上得到的结果返回给internet上请求连接的客户端，此时代理服务器对外就表现为一个反向代理服务器。
本文意在搭建一台nginx反向代理服务器。
1、nginx的安装配置可参考博文：
2、修改nginx的配置文件，如下：
server { listen 8888; server_name localhost; }
修改为：
server { listen 80; server_name 192.168.1.20; //反向代理服务器IP location / { proxy_pass http://192.168.1.10; //web服务器IP proxy_redirect off; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; }
3、验证。在浏览器中访问192.168.1.20，看看处理请求的是不是192.168.1.10。
4、参考配置：
