关于linux:linux之yum源设置代理

个别在内网环境中,少数服务器是不能间接上外网的(为了平安),只有个别的服务器能够拜访外网,在不能拜访外网的服务器上安装软件因为依赖的问题很容易出错,装置不上来,这时候就能够借助能够上外网的服务器做代理来装置软件。

Centos7下设置代理案例

在A服务器装置nginx

咱们应用nginx作为yum的反向代理软件

> yum install nginx -y

配置nginx

> vim /etc/nginx/conf.d/yum.conf
 server {
        listen 80;
        server_name yum.com;
        location /centos/ {
            proxy_pass http://mirrors.aliyun.com/centos/ ;
        }

        location /epel/ {
            proxy_pass http://mirrors.aliyun.com/epel/ ;
        }
    }
//重启nginx
> nginx -s reload

批改B服务器的repo文件

//备份
> cp /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.bak
> vim /etc/yum.repos.d/CentOS-Base.repo

B服务器上批改/etc/hosts

目标是让B服务器能解析yum.com

> vim /etc/hosts
192.168.1.111 yum.com

验证B服务器是否能够解析

> ping yum.com

刷新yum缓存

> yum clean all
> yum makecache
