CentOS8 Yum源更新设置

简单粗暴的文式：

cd /etc/yum.repos.d

rm -rf *

vi CentOS.repo

将下载内容写入

[AppStream]

name=CentOS-$releasever - AppStream

#mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=AppStream&infra=$infra

baseurl=https://mirrors.aliyun.com/centos/$releasever/AppStream/$basearch/os/

gpgcheck=1

enabled=1

gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-centosofficial

[BaseOS]

name=CentOS-$releasever - Base

#mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=BaseOS&infra=$infra

baseurl=https://mirrors.aliyun.com/centos/$releasever/BaseOS/$basearch/os/

gpgcheck=1

enabled=1

gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-centosofficial

[extras]

name=CentOS-$releasever - Extras

#mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=extras&infra=$infra

baseurl=https://mirrors.aliyun.com/centos/$releasever/extras/$basearch/os/

gpgcheck=1

enabled=1

gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-centosofficial

保存之后

sudo yum makecache

即可。

其它方式：

CentOS

curl -o /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-vault-8.5.2111.repo

下载源repo，然后 yum makecache

CentOS7

curl -o /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-7.repo
