Nginx反向代理多个域名

## 简介 ##

由于公司内网有多台服务器的http服务要映射到公司外网静态IP，如果用路由的端口映射来做，就只能一台内网服务器的80端口映射到外网80端口，其他服务器的80端口只能映射到外网的非80端口。非80端口的映射在访问的时候要域名加上端口，比较麻烦。所以我们可以在内网搭建个nginx反向代理服务器，将nginx反向代理服务器的80映射到外网IP的80，这样指向到公司外网IP的域名的HTTP请求就会发送到nginx反向代理服务器，利用nginx反向代理将不同域名的请求转发给内网不同机器的端口，**就起到了“根据域名自动转发到相应服务器的特定端口”的效果**，而路由器的端口映射做到的只是“根据不同端口自动转发到相应服务器的特定端口”，真是喜大普奔啊。

## Nginx配置 ##

vim /usr/local/nginx/conf/reverse-proxy.conf

<table style="margin:0px; padding:0px; border:none; outline:0px; font-weight:inherit; font-style:inherit; font-family:inherit; font-size:16px; vertical-align:middle; border-collapse:collapse; border-spacing:0px; width:auto">

在nginx.conf的http节点中include配置文件reverse-proxy.conf

## 测试生效 ##

热部署nginx配置

在客户机的hosts中配置tomcat1.vip.com和tomcat2.vip.com （如果是已申请好的域名，则可跳过此步骤）

从以上访问结果来看，浏览器的请求会分别引导到了tomcat1和tomcat2上。
