1. Cent OS 7 epel源安装
由于Centos 7与老版本有着巨大的差别，所以各种软件包都无法沿用老版本的，所以若使用老版本的扩展yum源，就会导致yum出现严重错误，无法安装大量软件包，不过epel源已经支持了Centos 7，只要添加即可
1.1 安装
运行命令编辑yum源：vim /etc/yum.repos.d/epel.repo
按i进入编辑模式，粘贴下面的代码：
[epel]
name=Extra Packages for Enterprise Linux 7 - $basearch
#baseurl=http://download.fedoraproject.org/pub/epel/7/$basearch
mirrorlist=https://mirrors.fedoraproject.org/metalink?repo=epel-7&arch=$basearch
failovermethod=priority
enabled=1
gpgcheck=0
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-7
[epel-debuginfo]
name=Extra Packages for Enterprise Linux 7 - $basearch - Debug
#baseurl=http://download.fedoraproject.org/pub/epel/7/$basearch/debug
mirrorlist=https://mirrors.fedoraproject.org/metalink?repo=epel-debug-7&arch=$basearch
failovermethod=priority
enabled=0
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-7
gpgcheck=1
[epel-source]
name=Extra Packages for Enterprise Linux 7 - $basearch - Source
#baseurl=http://download.fedoraproject.org/pub/epel/7/SRPMS
mirrorlist=https://mirrors.fedoraproject.org/metalink?repo=epel-source-7&arch=$basearch
failovermethod=priority
enabled=0
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-7
gpgcheck=1
:wq保存退出
运行命令即可：yum makecache
或直接使用yum install epel-release -y安装epel源。
如果使用yum install epel-release -y还是无法更新 yum 源的话有可能是源的禁用掉了
编辑文件vim /etc/yum.repos.d/epel.repo，将第一个和第三个中的enabled改为1
[epel]
