修改linux下yum镜像源为国内镜像

修改为163yum源-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

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

 

3、查看CentOS系统版本

[root@localhost ~]lsb_release -a

 

4、下载163的yum源配置文件到上面那个文件夹内

CentOS7

[root@localhost yum.repos.d]# wget http://mirrors.163.com/.help/CentOS7-Base-163.repo

CentOS6

[root@localhost yum.repos.d]# wget http://mirrors.163.com/.help/CentOS6-Base-163.repo

CentOS5

[root@localhost yum.repos.d]# wget http://mirrors.163.com/.help/CentOS5-Base-163.repo

 

5、运行yum makecache生成缓存

[root@localhost yum.repos.d]# yum makecache

 

6、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


修改为阿里yum源-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

[root@localhost ~]# mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup

 

2、查看CentOS系统版本

[root@localhost ~]lsb_release -a

 

3、下载ailiyun的yum源配置文件到/etc/yum.repos.d/
CentOS7

[root@localhost ~]# wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo

CentOS6

[root@localhost ~]# wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-6.repo

[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
