*  使用Nginx制作内网yum镜像代理
    
     *  背景
     *  环境需求
     *  Nginx安装配置

## 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 ##

1.  内网dns（推荐，非必须，因为可使用IP代替）
2.  一台能上Internet的服务器A
3.  不能上Internet的服务器能与A服务器通信
4.  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 http://mirrors.aliyun.com/ubuntu/ ;
            }
    
            location /centos/ {
                proxy_pass http://mirrors.aliyun.com/centos/ ;
            }
    
            location /epel/ {
                proxy_pass http://mirrors.aliyun.com/epel/ ;
            }
    }

> 以上使用阿里云镜像，其镜像版本很全，速度也很快。
