通过yum安装软件报错：

# yum install -y epel-release

Loaded plugins: fastestmirror

Loading mirror speeds from cached hostfile

Error: Cannot retrieve metalink for repository: epel. Please verify its path and try again

# vi /etc/yum.repos.d/epel.repo

处理很简单，修改文件“/etc/yum.repos.d/epel.repo”， 将baseurl的注释取消， mirrorlist注释掉，即可

具体如下：

[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
