[[email protected] Packages]# rpm -e $(rpm -qa | grep yum) --nodeps[[email protected] Packages]# echo $?0

2. Delete Yum related files

[[email protected] Packages]# rm -rf /etc/yum.conf[[email protected] Packages]# rm -rf /etc/yum.repos.d/*[[email protected] Packages]# rm -rf /var/cache/yum

3. Download CentOS-related Yum components

wget Https://mirrors.tuna.tsinghua.edu.cn/centos/7/os/x86_64/Packages/yum-3.4.3-158.el7.centos.noarch.rpmwget Https://mirrors.tuna.tsinghua.edu.cn/centos/7/os/x86_64/Packages/yum-metadata-parser-1.1.4-10.el7.x86_64.

4. Create a new repo file

[Base]name=centos-7-basebaseurl=https://mirrors.tuna.tsinghua.edu.cn/centos/7/os/$basearch/#mirrorlist =http:// Mirrorlist.centos.org/?release=7&arch= $basearch &repo=osgpgcheck=1gpgkey=file:///etc/pki/rpm-gpg/ rpm-gpg-key-centos-7#released updates[updates]name=centos-7-updatesbaseurl=https://mirrors.tuna.tsinghua.edu.cn /centos/7/updates/$basearch/#mirrorlist =http://mirrorlist.centos.org/?release=7&arch= $basearch &repo= Updatesgpgcheck=1gpgkey=file:///etc/pki/rpm-gpg/rpm-gpg-key-centos-7#additional packages that could be Useful[extras] Name=centos-7-extrasbaseurl=https://mirrors.tuna.tsinghua.edu.cn/centos/7/extras/$basearch/#mirrorlist =http:// Mirrorlist.centos.org/?release=7&arch= $basearch &repo=extrasgpgcheck=1gpgkey=file:///etc/pki/rpm-gpg/ Rpm-gpg-key-centos-7#additional packages that extend functionality of existing packages[centosplus]name=centos-7- plusbaseurl=https://mirrors.tuna.tsinghua.edu.cn/centos/7/centosplus/$basearch/#mirrorlist =http:// Mirrorlist.centOs.org/?release=7&arch= $basearch &repo=centosplusgpgcheck=1enabled=0gpgkey=file:///etc/pki/rpm-gpg/ Rpm-gpg-key-centos-7

5. Flush the build cache using Yum Makecache

6.epel Extension Source

First install the epel-release from the CentOS Extras source (Tuna also has a mirror):

yum install epel-release -y

Edit Epel.repo
