上面从 http://mirrors.aliyun.com/repo/Centos-8.repo 下载的文件并不能直接使用，需要根据需要做如下修改：
- 查看当前centos版本
cat /etc/redhat-release
CentOS Linux release 8.5.2111
当前的版本时8.5.2111，然后看https://mirrors.aliyun.com/centos-vault/ 有没有对应的版本：
然后修改Centos-8.repo：
# CentOS-Base.repo
#
# The mirror system uses the connecting IP address of the client and the
# update status of each mirror to pick mirrors that are updated to and
# geographically close to the client. You should use this for CentOS updates
# unless you are manually picking other mirrors.
#
# If the mirrorlist= does not work for you, as a fall back you can try the
# remarked out baseurl= line instead.

或者改成如下：
CentOS-Base.repo:

# The mirror system uses the connecting IP address of the client and the
