[root@zh888 yum.repos.d]# ls //首先备份一下yum.repos.d目录文件到backup中然后创建vi yum.repo文件。

backup  yum.repo
[root@zh888 yum.repos.d]# cat yum.repo 
[zh888]第一行：yum源的标签
name=zh888第二行：yum源的名称
baseurl=file:///mnt第三行：指定yum源的具体位置及路径
enable=1第四行：这个就好像是电源开关，也就是yum的开关，1为可用，等于0时不可用
gpgcheck=1第五行：数字签名检查，没有数字签名不允许安装，等于0时不进行数字签名检查。
gpgfile=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6第六行：指定Red Hat发行版数字签名公钥文件

[root@zh888 yum.repos.d]# mount /dev/cdrom /mnt//挂载iso文件到/mnt目录下
[root@zh888 yum.repos.d]# ls -l /dev/cdrom
lrwxrwxrwx 1 root root 3 Apr 12 18:16 /dev/cdrom -> sr //其实cdrom只是指向sr设备的软连接。

mount: block device /dev/sr0 is write-protected, mounting read-only
[root@zh888 yum.repos.d]# ls /mnt
