CentOS

备份旧源文件

mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.bak

下载阿里 CentOS7 归档源

curl -o /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-7.repo

如果 curl 命令不存在，用 wget：

wget -O /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-7.repo

清理并重建 yum 缓存

yum clean all
yum makecache

如果 wget /curl 都不能用，网络不通无法下载 repo 文件

手动编辑 vim /etc/yum.repos.d/CentOS-Base.repo，复制下面全部内容粘贴进去：
