CentOS停止维护后，很多yum源无法使用，可以自定义更改到阿里提供的源。
yum
https://developer.aliyun.com/mirror/centos
wget -O /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-7.repo
sudo yum clean all
sudo yum makecache
epel仓库
https://developer.aliyun.com/mirror/epel
备份(如有配置其他epel源)
mv /etc/yum.repos.d/epel.repo /etc/yum.repos.d/epel.repo.backup
mv /etc/yum.repos.d/epel-testing.repo /etc/yum.repos.d/epel-testing.repo.backup
下载安装
wget -O /etc/yum.repos.d/epel.repo https://mirrors.aliyun.com/repo/epel-7.repo
