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
