刚安装完的CentOS系统，默认带的yum镜像源一般都是国外的，导致在线安装的时候，速度很慢。这个时候需要你更换yum镜像源为国内的，国内主要开源的开源镜像点应该算是阿里和网易了。

\*\*网易：[http://mirrors.163.com.centos/][http_mirrors.163.com.centos]  
阿里云：[http://mirros.aliyun.com/centos][http_mirros.aliyun.com_centos]\*\*

**修改CentOS默认yum源为mirrors.163.com**

1、备份系统自带的yum镜像源 /etc/yum.repos.d/CentOS-Base.repo

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

2、查看自己按照的centOS系统的版本

[root@betty ~]# cat /etc/system-release 
    CentOS release 6.7 (Final)

3、根据系统版本号，下载对应yum源配置文件到上面那个文件夹内

进入到yum源配置文件所在的文件夹

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

CentOS7

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

CentOS6

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

CentOS5

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

4、运行yum生成缓存

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

5、更新系统就能看到mirrors.163.com信息

[root@betty yum.repos.d]# yum -y update 
    Loaded plugins: fastestmirror, refresh-packagekit, security  
    Setting up Update Process  
    Repository base is listed more than once in the configuration  
    Repository updates is listed more than once in the configuration  
    Repository extras is listed more than once in the configuration  
    Repository centosplus is listed more than once in the configuration  
    Repository contrib is listed more than once in the configuration  
    Loading mirror speeds from cached hostfile  
     * base: mirrors.163.com  
     * extras: mirrors.163.com  
     * updates: mirrors.163.com

用阿里云，只要下载aliyun的yum配置文件到/etc/yum.repos.d/，其它步骤一致  
CentOS7

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

CentOS6

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

CentOS5

[root@betty yum.repos.d]# wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-5.repo
