国内主要开源的开源镜像站点应该是网易和阿里云了。
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
# CentOS-Base.repo
#
# The mirror system uses the connecting IP address of the client and the
# update status of each mirror to pick mirrors that are updated to and
# geographically close to the client. You should use this for CentOS updates
# unless you are manually picking other mirrors.
#
# If the mirrorlist= does not work for you, as a fall back you can try the
# remarked out baseurl= line instead.

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

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
