CentOS修改和更换YUM软件源方法教程

有时候CentOS默认的yum源不一定是国内镜像,导致yum在线安装及更新速度不是很理想。这时候需要将yum源设置为国内镜像站点。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
[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、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

4、运行yum makecache生成缓存

[root@localhost yum.repos.d]# 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
[root@localhost ~]# 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/
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 ~]# wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-5.repo
3、运行yum makecache生成缓存
[root@localhost ~]# 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
