1、备份
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/
wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-8.repo
3、生成缓存
yum makecache
CentOS8现已可使用国内的aliyun阿里云镜像站，方法如下:
用cd命令切换到yum.repos目录，备份原始的3个repo文件：
cd /etc/yum.repos.d/ sudo cp CentOS-AppStream.repo CentOS-AppStream.repo.bak sudo cp CentOS-Base.repo CentOS-Base.repo.bak sudo cp CentOS-Extras.repo CentOS-Extras.repo.bak
编辑上面3个repo文件，在mirrorlist前加个#，并把baseurl前的#去掉。 baseurl里的 mirror.centos.org/$contentdir 修改为 mirrors.aliyun.com/centos 即可。 以CentOS-AppStream.repo为例，其他两个文件同理。
sudo nano CentOS-AppStream.repo
修改前：
mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=AppStream&infra=$infra #baseurl=http://mirror.centos.org/$contentdir/$releasever/AppStream/$basearch/os/
修改后：
#mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=AppStream&infra=$infra baseurl=http://mirrors.aliyun.com/centos/$releasever/AppStream/$basearch/os/
sudo yum update
注意：如果使用的是CentOS8 Stream版本，还需要修改 CentOS-Stream-开头的3个repo文件。
修改完成后运行 sudo yum update 正常更新。
补充：epel-release的源可同理修改：
sudo yum -y install epel-release
sudo nano /etc/yum.repos.d/epel.repo

不要直接在虚拟机安装，在外面安装虚拟机
