1、备份旧的配置文件
1 | mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup |
2、下载新的 CentOS-Base.repo 到 /etc/yum.repos.d/
1 | wget -O /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-8.repo |
非阿里云ECS用户会出现 Couldn’t resolve host ‘mirrors.cloud.aliyuncs.com’ 信息，不影响使用。用户也可自行修改相关配置
1 | sed -i -e '/mirrors.cloud.aliyuncs.com/d' -e '/mirrors.aliyuncs.com/d' /etc/yum.repos.d/CentOS-Base.repo |
3、生成缓存
1 | yum makecache |
4、更新
1 | yum -y update |
