1、备份/etc/yum.repos.d/文件
[root@www ~]# cp -r /etc/yum.repos.d/ /etc/yum.repos.d.bak
[root@www ~]# ls /etc/yum.repos.d* -d
/etc/yum.repos.d /etc/yum.repos.d.bak
2.删除系统网络yum文件
[root@www ~]# rm -rf /etc/yum.repos.d/CentOS-Base.repo
[root@www ~]# yum repolist
Loaded plugins: fastestmirror
Loading mirror speeds from cached hostfile
repolist: 0
3.创建本地yum源配置文件
[root@www ~]# vim /etc/yum.repos.d/cdrom.repo
[cdrom]
name=cdrom
baseurl=file:///mnt/cdrom
gpgcheck=0
enable=1
4.虚拟机连接DVD，挂载光驱
[root@www ~]# mkdir /mnt/cdrom
[root@www ~]# mount /dev/sr0 /mnt/cdrom/
mount: block device /dev/sr0 is write-protected, mounting read-only
5.列出yum仓库
[root@www ~]# yum repolist
[root@www ~]# yum install samba
6.删除yum进程
[root@www ~]# rm -f /var/run/yum.pid
