CentOS 8.0配置阿里云yum源和epel源

1、一键配置CentOS 8.0一键配置阿里云yum源和epel源脚本：
curl -o centos8.proyy.com.repo https://www.proyy.com/wp-content/uploads/2020/07/2798727987.repo&&mv /etc/yum.repos.d/*.repo ./ &&cp -rp centos8.proyy.com.repo /etc/yum.repos.d/centos8.proyy.com.repo&& yum clean all&&yum makecache&&yum install -y www.proyy.com
CentOS 8.0阿里云yum源文件下载：
CentOS8-Base.repo
2、配置CentOS 8.0配置阿里云yum源和epel源

# cd /etc/yum.repos.d
# vim CentOS-AppStream.repo
baseurl=https://mirrors.aliyun.com/centos/$releasever/AppStream/$basearch/os/

# vim CentOS-Base.repo
baseurl=https://mirrors.aliyun.com/centos/$releasever/BaseOS/$basearch/os/
# vim CentOS-Extras.repo
baseurl=https://mirrors.aliyun.com/centos/$releasever/extras/$basearch/os/
# dnf -y install epel-release
# dnf clean all
# dnf makecache
# dnf repolist
3、或者直接参考以下配置最新centos8.0配置阿里云yum镜像源：
# 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.
#
