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

    CentOS 7

    wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-5.repo

    3、之后运行yum makecache生成缓存

    http://mirrors.aliyun.com/help/centos

    文件位于centos目录  /etc/yum.repos.d/  下。

    阿里的更新源: CentOS-7

    # CentOS-Base.repo
    #
    # The mirror system uses the connecting IP address of the client and the
    # update status of each mirror to pick mirrors that are updated to and
    # geographically close to the client.  You should use this for CentOS updates
    # unless you are manually picking other mirrors.
    #
    # If the mirrorlist= does not work for you, as a fall back you can try the
    # remarked out baseurl= line instead.
    #
