二、🔊Epel 镜像简介
EPEL (Extra Packages for Enterprise Linux), 是由 Fedora Special Interest Group 维护的 Enterprise Linux（RHEL、CentOS）中经常用到的包。
三、🎄 配置方法
1、更新YUM源🎃
[root@centos ~]# yum clean all
[root@centos ~]# yum repolist
2、 备份(如有配置原来的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
3、下载新repo 到/etc/yum.repos.d/🏆
1）安装 epel 配置包💎
安装对应的安装包（本实验以CentOS 7系统为例）

2）将 repo 配置中的地址替换为阿里云镜像站地址👑
sed -i 's|^#baseurl=https://download.example/pub|baseurl=https://mirrors.aliyun.com|' /etc/yum.repos.d/epel*
sed -i 's|^metalink|#metalink|' /etc/yum.repos.d/epel*
[root@centos yum.repos.d]# sed -i 's|^#baseurl=https://download.example/pub|baseurl=https://mirrors.aliyun.com|' /etc/yum.repos.d/epel*
[root@centos yum.repos.d]# sed -i 's|^metalink|#metalink|' /etc/yum.repos.d/epel*
4、更新YUM源🔒
[root@centos yum.repos.d]# yum clean all
Loaded plugins: fastestmirror
Cleaning repos: base epel extras updates
