The following is a proxy way to make a virtual host in the Nginx configuration;

1. In the nginx.conf code:

650) this.width=650; "src=" Http://s5.51cto.com/wyfs02/M01/7E/02/wKiom1b01nShY7fVAAAJ6VrqElI490.png "title=" 1.png " alt= "Wkiom1b01nshy7fvaaaj6vrqeli490.png"/>

2. Create a new directory for CONF.D

3. There are two configuration files in the CONF.D directory

The configuration file in ceshi.test.cn.conf is similar to nginx configuration;

Ceshi.test.cn-proxy.conf

is the basic content of ceshi.test.cn-proxy.conf

650) this.width=650; "src=" Http://s2.51cto.com/wyfs02/M02/7D/FE/wKioL1b02HnSpaPBAABiddFTdPU513.png "title=" 2.png " Width= "height=" 340 "border=" 0 "hspace=" 0 "vspace=" 0 "style=" width:500px;height:340px; "alt=" Wkiol1b02hnspapbaabiddftdpu513.png "/>
