1.配置網絡yum源
[root@localhost ~]# cd /etc/yum.repos.d/
[root@localhost yum.repos.d]# mkdir bak
[root@localhost yum.repos.d]# mv *.repo bak/
[root@localhost yum.repos.d]# ls
bak
[root@localhost yum.repos.d]# wget http://mirrors.aliyun.com/repo/Centos-7.repo
[root@localhost yum.repos.d]# wget http://mirrors.163.com/.help/CentOS7-Base-163.repo
[root@localhost yum.repos.d]# ls
bak CentOS7-Base-163.repo Centos-7.repo
[root@localhost ~]# yum clean all
[root@localhost ~]# yum repolist
...此處省略
repo id repo name status
!base/7/x86_64 CentOS-7 - Base - 163.com 10,070
!extras/7/x86_64 CentOS-7 - Extras - 163.com 342
!updates/7/x86_64 CentOS-7 - Updates - 163.com 159
repolist: 10,571
本次安裝用的是阿里和163的源，你也可以下載別的源進行安裝。
2.配置本地yum源
[root@node2 ~]# cd /etc/yum.repos.d/
[root@node2 yum.repos.d]# mkdir bak
[root@node2 yum.repos.d]# mv *.repo bak/
[root@node2 yum.repos.d]# cat local.repo
[Centos7]
name=hxh
baseurl=file:///mnt/cdrom/
gpgcheck=0
enabled=1
[root@node2 yum.repos.d]# mkdir /mnt/cdrom/
[root@node2 yum.repos.d]# mount /dev/cdrom /mnt/cdrom/
[root@node2 yum.repos.d]# yum clean all
已加載插件：fastestmirror
正在清理軟件源： Centos7
...
[root@node2 yum.repos.d]# yum repolist
已加載插件：fastestmirror
Determining fastest mirrors
Centos7 | 3.6 kB 00:00:00
(1/2): Centos7/group_gz | 165 kB 00:00:00
(2/2): Centos7/primary_db | 3.2 MB 00:00:00
源標識 源名稱 狀態
Centos7 hxh 4,067
repolist: 4,067
[root@node2 yum.repos.d]#
3.配置共享yum源
您可以自己搭建web,然後掛載到web下，編寫yum倉庫即可
