使用nginx制作内网yum镜像代理

• 使用Nginx制作内网yum镜像代理

  • 1. 背景

  • 2. 环境需求

  • 3. 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。
