centos7 更换yum源

mkdir /etc/yum.repos.d/bak
    mv /etc/yum.repos.d/*.repo /etc/yum.repos.d/bak/
    # ---用wget下载
    # cd /etc/yum.repos.d
    # wget -nc http://mirrors.aliyun.com/repo/Centos-7.repo
    # 更改阿里yum源为默认源
    # mv CentOS-7.repo CentOS-Base.repo
    
    # ---如果没有wget命令 可以用cat
    cat > /etc/yum.repos.d/CentOS-Base.repo <<EOF # 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.
