使用Nginx制作内网yum镜像代理

1. 背景

公司内网服务器不能直接通过Internet上网，但为了与外网通信和同步时间等，会指定那么几台服务器可以访问Internet。这里就是通过能上网的机器作为代理，制作内网使用的yum仓库。

2. 环境需求

内网dns（推荐，非必须，因为可使用IP代替）

一台能上Internet的服务器A

不能上Internet的服务器能与A服务器通信

这里示例为CentOS7和Ubuntu16

3. Nginx安装配置

Nginx安装在能上网的A服务器上，安装过程略。 
具体一个nginx server配置如下：

# mirrors
server
   {
       listen 80;
       #listen [::]:80;
       server_name mirrors.yourdomain.com;
       index index.html index.htm index.php default.html default.htm default.php;
       root  /home/wwwroot/html;

       location /ubuntu/ {
           proxy_pass ;
       }

       location /centos/ {
           proxy_pass ;
       }

       location /epel/ {
           proxy_pass ;
       }
}

以上使用阿里云镜像，其镜像版本很全，速度也很快。
