CentOS 7 配置清华大学EPEL镜像

一.备份 CentOS-Base.repo

sudo cp /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.bak

二.配置CentOS-Base.repo

使用下面配置覆盖/etc/yum.repos.d/CentOS-Base.repo文件

# CentOS-Base.repo
#
# The mirror system uses the connecting IP address of the client and the
# update status of each mirror to pick mirrors that are updated to and
# geographically close to the client.  You should use this for CentOS updates
# unless you are manually picking other mirrors.
#
# If the mirrorlist= does not work for you, as a fall back you can try the
# remarked out baseurl= line instead.
#
#


[base]
name=CentOS-$releasever - Base
baseurl=https://mirrors.tuna.tsinghua.edu.cn/centos/$releasever/os/$basearch/
#mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=os
enabled=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-7

#released updates
[updates]
name=CentOS-$releasever - Updates
baseurl=https://mirrors.tuna.tsinghua.edu.cn/centos/$releasever/updates/$basearch/
#mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=updates
enabled=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-7



#additional packages that may be useful
[extras]
name=CentOS-$releasever - Extras
baseurl=https://mirrors.tuna.tsinghua.edu.cn/centos/$releasever/extras/$basearch/
#mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=extras
enabled=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-7



#additional packages that extend functionality of existing packages
[centosplus]
name=CentOS-$releasever - Plus
baseurl=https://mirrors.tuna.tsinghua.edu.cn/centos/$releasever/centosplus/$basearch/
#mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=centosplus
gpgcheck=1
enabled=0
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-7

如果不想检查gpg公钥，则gpgcheck都设0.

更新下

yum clean all

三.安装EPEL镜像

yum -y install epel-release

四.配置EPEL

使用下面命令替换epel使用清华大学源

sed -e 's!^metalink=!#metalink=!g' 
    -e 's!^#baseurl=!baseurl=!g' 
    -e 's!//download.fedoraproject.org/pub!//mirrors.tuna.tsinghua.edu.cn!g' 
    -e 's!http://mirrors.tuna!https://mirrors.tuna!g' 
    -i /etc/yum.repos.d/epel.repo /etc/yum.repos.d/epel-testing.repo

五.更简便的使用EPEL镜像的方法

rpm -ivh https://mirrors.tuna.tsinghua.edu.cn/epel/6/x86_64/epel-release-6-8.noarch.rpm
