解决方案

1、进入yum的repos目录

cd /etc/yum.repos.d/

2、修改所有的CentOS文件内容

sed -i 's/mirrorlist/#mirrorlist/g' /etc/yum.repos.d/CentOS-*

sed -i 's|#baseurl=http://mirror.centos.org|baseurl=http://vault.centos.org|g' /etc/yum.repos.d/CentOS-*

 

3、更新yum源为阿里镜像

wget -O /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-vault-8.5.2111.repo

yum clean all

yum makecache
