yum安装时出现：Cannot retrieve metalink for repository: epel. Please verify its path and try again

在CentOS 6.3 x86_64下安装php-mcrypt的时候出现了问题：Error: Cannot retrieve metalink for repository: epel. Please verify its path and try again，CentOS自身的源是没有php-mcrypt的，所以使用 yum install php-mcrypt是没有这个包。因此需要安装epel源。

先

1. wget http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm
2. rpm -U epel-release-6-8.noarch.rpm
3. yum install php-mcrypt

接下来就出现了：

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

打开/etc/yum.repos.d/epel.repo，将

1. [epel]
2. name=Extra Packages for Enterprise Linux 6 - $basearch
3. #baseurl=http://download.fedoraproject.org/pub/epel/6/$basearch
4. mirrorlist=https://mirrors.fedoraproject.org/metalink?repo=epel-6&arch=$basearch

修改为

1. [epel]
2. name=Extra Packages for Enterprise Linux 6 - $basearch
3. baseurl=http://download.fedoraproject.org/pub/epel/6/$basearch
4. #mirrorlist=https://mirrors.fedoraproject.org/metalink?repo=epel-6&arch=$basearch

再清理源，重新安装

1. yum clean all
2. yum install php-mcrypt

如果还是不行，修改DNS,到/etc/resolv.conf下添加一下：

nameserver 8.8.8.8
search localdomain

然后重启network服务

yum安装时出现：Cannot retrieve metalink for repository: epel. Please verify its path and try again
