CentOS7 加阿里yum源

CentOS系统更换软件安装源

第一步：备份原镜像文件，以免出错后可以恢复。
cp -r /etc/yum.repos.d/ /etc/yum.repos.d.bak/

第二步：下载新的CentOS-Base.repo 到/etc/yum.repos.d/
curl -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo(可能不好用)
第三步：运行yum makecache生成缓存
yum clean all
yum makecache

 

阿里云epel.repo
