RHEL8配置Yum源及测试thefuck

QDFILMRHEL8配置Yum源及测试thefuck

长春密刺1. 配置Yum源

RHEL系统安装完成之后，如果没有注册并购买红帽服务是⽆法连接到官⽅的Yum源的，也就⽆法直接使⽤Yum命令来安装软件包及更新系统。1

发动机摇臂

但是，我们可以禁⽤“Subscription Management”，然后配置成我们⾃⼰定义的Yum源，也就是Repository库。可以⾃定义, 这个很简单，可参考之前的⽂档。这⾥我们使⽤阿⾥云开源镜像。

阿⾥云开源镜像

mirrors.aliyun/repo/

下载po 到/pos.d/

cd /pos.d/

wget mirrors.aliyun/po
