本文介绍下，用nginx实现反向代理配置的例子，有需要的朋友参考下。nginx反向代理的指令不需要新增额外的模块，默认自带proxy_pass指令，只需要修改配置文件就可以实现反向代理。
       然后，新建一个vhost.conf，加入如下内容。

## Basic reverse proxy server ##
## Apache backend for www.quancha.cn ##
upstream apachephp  {
    server ip:8080; #Apache
}

    root   html;
    index  index.html index.htm index.php;

    ## send request back to apache ##
