Using the yum makecache command is also the same problem. After searching for a solution, I didn’t find any useful ones. Finally, I found the above three articles.
reason:
Since centos8 will stop serving in 2022, the successor version will be 8-steam. An error is reported when using Aliyun's centos8 yum.
According to the above, just replace the version number. You
can test the address in the error message
https://mirrors.aliyun.com/centos/8/BaseOS/x86_64/os/repodata/repomd.xml
and replace 8 with 8- The stream
description is indeed a version problem, because the first two tests are too cumbersome, directly follow the third method
solution
1. Enter the configuration file and delete all .repo files (you can also back them up)
#进入配置文件夹
cd /etc/yum.repos.d/
#删除旧的配置文件
rm *.repo
#输入“y”回车确认
ls Make sure that the .repo file in this directory has been completely deleted
Download the available .repo file
wget -O /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-vault-8.5.2111.repo
If you don't have wget installed, you can also use the following command:
curl -o /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-vault-8.5.2111.repo
Run yum makecache to generate cache
yum makecache
Complete
the installation of git is also successful
