1、配置epel源 [root@localhost ~]# cd /etc/yum.repos.d/ [root@localhost yum.repos.d]# wget -O /etc/yum.repos.d/epel-7.repo http://mirrors.aliyun.com/repo/epel-7.repo --2017-12-01 17:08:56-- http://mirrors.aliyun.com/repo/epel-7.repo Resolving mirrors.aliyun.com (mirrors.aliyun.com)... 180.163.159.88, 180.163.159.87, 180.163.159.84, ...
