Centos Stream 9 换DNF源

RHEL9 出来啦，没钱买订阅，试试Centos Stream 9体验体验

前置声明

本教程目前使用的是清华源，目前阿里云没有对应的镜像

以下命令均可以使用dnf代替

开始替换

删除原来的源

首先，我们前往文件夹/etc/yum.repos.d/下面的，删除所有的文件

具体命令如下

1 2	cd /etc/yum.repos.d/ rm -rf ./*

导入新的源

我们在刚才的目录下，新建一个文件Centos.repo，接着导入下面这些信息

[baseos]
name=CentOS Stream $releasever - BaseOS
#mirrorlist=http://mirrorlist.centos.org/?release=$stream&arch=$basearch&repo=BaseOS&infra=$infra
baseurl=https://mirrors.ustc.edu.cn/centos-stream/9-stream/BaseOS/$basearch/os/
gpgcheck=1
enabled=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-centosofficial
[appstream]
name=CentOS Stream $releasever - AppStream
#mirrorlist=http://mirrorlist.centos.org/?release=$stream&arch=$basearch&repo=AppStream&infra=$infra
baseurl=https://mirrors.ustc.edu.cn/centos-stream/9-stream/AppStream/$basearch/os/
gpgcheck=1
enabled=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-centosofficial

具体命令如下

cd /etc/yum.repos.d/
touch Centos.repo
vim Centos.repo
