在CentOS 6安裝epel后出問(wèn)題冷蚂，報(bào)錯(cuò)：Error: Cannot retrieve metalink for repository: epel. Please verify its path and try again粱侣，需要安裝epel源。
解決方法：
一句話(huà)：把/etc/yum.repos.d/epel.repo卫袒，文件第3行注釋去掉，把第四行注釋掉通砍。具體如下：
打開(kāi)/etc/yum.repos.d/epel.repo玛臂，將
[epel]
name=ExtraPackagesforEnterpriseLinux6-$basearch
#baseurl=http://download.fedoraproject.org/pub/epel/6/$basearch
mirrorlist=https://mirrors.fedoraproject.org/metalink?repo=epel-6&arch=$basearch
修改為
[epel]
name=ExtraPackagesforEnterpriseLinux6-$basearch
baseurl=http://download.fedoraproject.org/pub/epel/6/$basearch
#mirrorlist=https://mirrors.fedoraproject.org/metalink?repo=epel-6&arch=$basearch
再清理源，重新安裝
yum clean all
yum install -y 需要的包
如果還是不行封孙，修改DNS,到/etc/resolv.conf下添加一下：
nameserver 8.8.8.8
search localdomain
然后重啟network服務(wù)：service network restart
