修改CentOS默认yum源

修改CentOS默认yum源

有时候CentOS默认的yum源不一定是国内镜像，导致yum在线安装及更新速度不是很理想。需要将yum源设置为国内镜像站点。

1.备份系统旧配置文件

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

2、进入yum源配置文件所在的文件夹

[root@linux ~]# cd /etc/yum.repos.d/

3、下载mirrors.cloud.tencent.com的yum源配置文件到上面那个文件夹内

CentOS5

wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.cloud.tencent.com/repo/centos5_base.repo

CentOS6

wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.cloud.tencent.com/repo/centos6_base.repo

CentOS7

CentOS8
