[root@raoyuuuu maven]# dnf install git

CentOS-8 - Base - mirrors.aliyun.com
Errors during downloading metadata for repository 'base':
- Curl error (28): Timeout was reached for http://mirrors.aliyuncs.com/centos/8/BaseOS/x86_64/os/repodata/repomd.xml [Connection timed out after 30000 milliseconds]

Error: Failed to download metadata for repo 'base': Cannot download repomd.xml: Cannot download repodata/repomd.xml: All mirrors were tried
使用yum makecache命令也是一样的问题
原因:
由于centos8 在2022年停止服务,后继版本为8-steam。在使用阿里云的 centos8 的 yum 时报错。
根据上面的说明,只需更换版本号即可。
[En]
According to the above, just replace the version number.
您可以使用错误消息中的地址对其进行测试。
[En]
You can test it with the address in the error message.
将8替换成8-stream
描述确实是版本的问题,因为前两个测试太乏味了,所以直接遵循第三篇文章的方法。
[En]
The description is really a problem with the version, because the first two tests are too tedious, so follow the method of the third article directly.
解决方案
1、进入配置文件内,删除所有的.repo文件(也可以备份)
#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确保该目录下的.repo文件已完全删除
下载可以用的.repo文件
wget -O /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-vault-8.5.2111.repo
如果你没有安装wget,也可以用下面命令:
curl -o /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-vault-8.5.2111.repo
运行 yum makecache 生成缓存
yum makecache
完成
安装git也成功
