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。

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。
可以自定义本地Yum源, 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
https://mirrors.aliyun.com/repo/
下载CentOS-Base.repo 到/etc/yum.repos.d/
cd /etc/yum.repos.d/
wget https://mirrors.aliyun.com/repo/Centos-8.repo
cd /etc/yum.repos.d/
wget https://mirrors.aliyun.com/repo/Centos-8.repo
