centos7使用阿里云源 和一句话自动换源yum仓库

备份原有的YUM仓库配置文件

sudo mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup

2.下载阿里云的CentOS仓库配置文件

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

3.清理缓存并生成新的仓库缓存

sudo yum clean all 清理yum缓存

sudo yum makecache 生成新的缓存

yum update 更新yum源

完成上述步骤后，您的系统将使用阿里云的YUM仓库。您可以使用yum update来测试是否一切正常。
