解决方法可以试试修改“/etc/yum.repos.d”文件夹中的“epel.repo”文件。修改内容如下：

如果你系统“epel.repo”文件当中原内容如下，

[epel]name=ExtraPackagesforEnterpriseLinux7-$basearch#baseurl=http://download.fedoraproject.org/pub/epel/7/$basearchmetalink=https://mirrors.fedoraproject.org/metalink?repo=epel-7&arch=$basearchfailovermethod=priorityenabled=1gpgcheck=1gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-7

我们只需要把“metalink=https://mirrors.fedoraproject.org/metalink?repo=epel-7&arch=$basearch”前面加“#”号注释掉，并且把“#baseurl=http://download.fedoraproject.org/pub/epel/7/$basearch”取消注释！修改如下即可，一般这个问题就能得到解决了。
