使用 Nginx 制作内网 yum mirrors proxy

[TOC]

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 mirror proxy,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。 http://mirrors.aliyun.com/
