解決方案：找到配置文件打開 /etc/yum.repos.d 修改baseurl 爲阿里雲的地址 。

cd /etc/yum.repos.d

vi CentOS-Base.repo

## 修改爲如下內容

CentOS-Base.repo [BaseOS] name=CentOS-$releasever - Base baseurl=https://mirrors.aliyun.com/centos/$releasever/BaseOS/$basearch/os/

gpgcheck=1

enabled=1

gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-centosofficial

vi CentOS-AppStream.repo

## CentOS-AppStream.repo [AppStream] name=CentOS-$releasever - AppStream baseurl=https://mirrors.aliyun.com/centos/$releasever/AppStream/$basearch/os/

gpgcheck=1

enabled=1

gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-centosofficial

 

修改完之後執行 dnf命令或者yum 命令都可以

dnf clean all # 清除所有的緩存文件

dnf makecache # 製作元數據緩存
