Centos7更换yum源为阿里源

2020-07-21 11:45发布

1、备份源

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

2、下载新的 CentOS-Base.repo 到 /etc/yum.repos.d/

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

3、非阿里云ECS用户会出现 Couldn't resolve host 'mirrors.cloud.aliyuncs.com' 信息,不影响使用,可以修改配置

      sed -i -e '/mirrors.cloud.aliyuncs.com/d' -e '/mirrors.aliyuncs.com/d' /etc/yum.repos.d/CentOS-Base.repo 

4、生成缓存

      yum makecache 

5、查看当前源

      yum repolist
