2、下载新的 CentOS-Base.repo 到 /etc/yum.repos.d/

CentOS 7版本:

wget -O /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/re...

或者

curl -o /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/re...
[root@centos yum.repos.d]# wget -O /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-7.repo
