CentOS7配置阿里云yum源和EPEL源

1.备份

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

wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo

3、之后运行yum clean all 清除缓存，运行 yum makecache 生成新的缓存

安装EPEL源

[root@bogon yum.repos.d]# yum list | grep epel-release

epel-release.noarch 7-9 extras
[root@bogon yum.repos.d]# yum install -y epel-release
