Centos 8 更换yum源的方法

首先备份原来的源文件,防止更改失误可进行恢复。 [root@master ~]# cp -a /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.bak CentOS-8的官方源安装方法: [root@master ~]# wget -O /etc/yum.repos.d/CentOS-Base.repo https://repo.huaweicloud.com/repository/conf/CentOS-8-reg.repo 由于CentOS-8的官方源已下线 请使用下方 CentOS-Vault 的源。 [root@master ~]# wget -O /etc/yum.repos.d/CentOS-Base.repo https://repo.huaweicloud.com/repository/conf/CentOS-8-reg.repo

清除原有yum缓存。 [root@master ~]# yum clean all 刷新缓存 [root@master ~]# yum makecache

如需使用HighAvailability 请编辑文件 [root@master ~]# vim /etc/yum.repos.d/CentOS-Base.repo

增加以下内容 [HighAvailability] name=CentOS-$releasever - pcs - repo.huaweicloud.com baseurl=https://repo.huaweicloud.com/centos-vault/8.5.2111/HighAvailability/$basearch/os/ gpgcheck=1 gpgkey=https://repo.huaweicloud.com/centos/RPM-GPG-KEY-CentOS-Official

清除原有yum缓存。 [root@master ~]# yum clean all 刷新缓存 [root@master ~]# yum makecache

查看centos-8.repo [root@Master ~]# cat /etc/yum.repos.d/centos-8.repo
