简介

在项目部署时，尤其是在政府企业，对于外网简直是奢望，但是对于运维来说，没有外网的话只能自建yum源。我今天来说的是一种简单的自建yum源方法，前提是必须有一台内外网都有的机器，我们一般称为前置机。

操作思路

1、使用nginx 反向代理 阿里云源

2、在内网机器自建repo指向nginxip

server
{
listen 80;

    location /centos/ {  
        proxy\_pass http://mirrors.aliyun.com/centos/ ;  
    }  

}

比较简单，不过我们要求不高能用即可。

另外我们常用的linux系统是Centos，所以我这边只写了Centos的。其它的你也可以参考上面配置配置。

内网机器配置

1、备份CentOS-Base.repo

# mv CentOS-Base.repo CentOS-Base.repo.bak

2、增加反向代理的repo
