修改CentOS的yum源为国内163和阿里的yum镜像源

点击数:0

修改CentOS默认yum源为mirrors.163.com

1.首先备份系统自带yum源配置文件/etc/yum.repos.d/CentOS-Base.repo

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

cd /etc/yum.repos.d/

3.下载163的yum源配置文件到上面那个文件夹内

CentOS8:

wget http://mirrors.163.com/.help/CentOS8-Base-163.repo

CentOS7:

wget http://mirrors.163.com/.help/CentOS7-Base-163.repo

CentOS6:

wget http://mirrors.163.com/.help/CentOS6-Base-163.repo

CentOS5:

wget http://mirrors.163.com/.help/CentOS5-Base-163.repo

4.运行yum makecache生成缓存

yum makecache

5.这时候再更新系统就会看到以下mirrors.163.com信息

[root@localhost yum.repos.d]# yum -y update
已加载插件:fastestmirror, refresh-packagekit, security
设置更新进程Loading mirror speeds from cached hostfile
* base: mirrors.163.com
* extras: mirrors.163.com
* updates: mirrors.163.com

修改CentOS默认yum源为mirrors.aliyun.com

1、首先备份系统自带yum源配置文件/etc/yum.repos.d/CentOS-Base.repo

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

2、下载ailiyun的yum源配置文件到/etc/yum.repos.d/

CentOS 8

wget -O /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-8.repo

CentOS7

wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo

CentOS6

wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-6.repo

CentOS5

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

需要注意的是各镜像站目前在Base.repo中附带了AppStream等其他源地址,而CentOS8原版是分拆为多个文件分别管理的。

阿里云还新增了PowerTools、centosplus等仓储地址。并将本地gpgkey路径改为了https://mirrors.aliyun.com/centos/RPM-GPG-KEY-CentOS-Official

3、运行yum makecache生成缓存

yum makecache

4、这时候再更新系统就会看到以下mirrors.aliyun.com信息

[root@localhost ~]# yum -y update
已加载插件:fastestmirror, refresh-packagekit, security
设置更新进程Loading mirror speeds from cached hostfile
* base: mirrors.aliyun.com
* extras: mirrors.aliyun.com
* updates: mirrors.aliyun.com
