CentOS 8 更换yum源

首先备份原来的yum源

mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup

接着下载yum源

wget -O /etc/yum.repos.d/CentOS-Base.repo https://www.landui.com/repo/Centos-8.repo

然后清除缓存

yum clean all && yum makecache

哦吼，这时会发现有报错，换源失败

下面是亲测centos8换源成功方法

首先备份下原来的文件

rename '.repo' '.repo.bak' /etc/yum.repos.d/*.repo

然后下载yum源

wget https://www.landui.com/repo/Centos-vault-8.5.2111.repo -O /etc/yum.repos.d/Centos-vault-8.5.2111.repo
wget https://www.landui.com/repo/epel-archive-8.repo -O /etc/yum.repos.d/epel-archive-8.repo

最后清除更新缓存

yum clean all && yum makecache

测试OK换源成功！
