CentOS7.8 换清华源和阿里源

第一步，清空所有repo文件

cd /etc/yum.repos.d/

删除所有文件:

rm -f /etc/yum.repos.d/*

第二步：配置清华源

新建两个文件vim CentOS-Base.repo和vim epel.repo

vim CentOS-Base.repo

# 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.
#

添加RPM-GPG-KEY-EPEL-7

curl https://mirrors.tuna.tsinghua.edu.cn/epel/RPM-GPG-KEY-EPEL-7 > /etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-7
