修改CentOS默認yum源

修改CentOS默認yum源

有時候CentOS默認的yum源不一定是國內鏡像，導致yum在線安裝及更新速度不是很理想。需要將yum源設置為國內鏡像站點。

騰訊源

1.備份系統舊配置文件

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

2、進入yum源配置文件所在的文件夾

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

3、下載mirrors.cloud.tencent.com的yum源配置文件到上面那個文件夾內

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

wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.cloud.tencent.com/repo/centos7_base.repo

CentOS8

wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.cloud.tencent.com/repo/centos8_base.repo

更新緩存

yum clean all
yum makecache
yum -y update
