安装完运行yum报错：
Error: Cannot retrieve metalink for repository: epel. Please verify its path and try again
提示原因为资源库路径获取错误，解决办法是改成正确的资源库路径即可。
解决办法：
vi /etc/yum.repos.d/epel.repo
编辑[epel]下的baseurl前的#号去掉，mirrorlist前添加#号。正确配置如下：
[epel]
name=Extra Packages for Enterprise Linux 6 - $basearch
baseurl=http://download.fedoraproject.org/pub/epel/6/$basearch
#mirrorlist=https://mirrors.fedoraproject.org/metalink?repo=epel-6&arch=$basearch
failovermethod=priority
enabled=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-6
再运行
yum makecache
或者
yum repolist
