Seeing that the error should be 404 when getting the XML file
Open the browser and enter https://mirrors.aliyun.com/centos/8/BaseOS/x86_64/os/repodata/repomd.xml
found inaccessible
Look up level by level and find that the directory can be accessed at https://mirrors.aliyun.com/centos/8/, but there is no basis in the subdirectory

Go back to the superior again to search in the centos directory and find that only
https://mirrors.aliyun.com/centos/8-stream/ There are yum baseOS repo files in the directory

Down the BaseOS path, I did find repomd.xml
So far, the problem has been found. It should be that Alibaba Cloud has changed the source file structure but there is no synchronous modification in the repo configuration file. You only need to modify the path information in the repo file.

Sed -i _ 's/$ releasever /8-stream/g' / etc / yum.repos.d / CentOS- Base.repo
