[root@zh888 yum.repos.d]# cat yum.repo

[zh888]第一行：yum源的標籤

name=zh888第二行：yum源的名稱

baseurl=file:///mnt第三行：指定yum源的具體位置及路徑

enable=1第四行：這個就好像是電源開關，也就是yum的開關，1為可用，等於0時不可用

gpgcheck=1第五行：數位簽章檢查，沒有數位簽章不允許安裝，等於0時不進行數位簽章檢查。

gpgfile=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6第六行：指定Red Hat發行版數位簽章公開金鑰檔案

[root@zh888 yum.repos.d]# mount /dev/cdrom /mnt//掛載iso檔案到/mnt目錄下

[root@zh888 yum.repos.d]# ls -l /dev/cdrom

lrwxrwxrwx 1 root root 3 Apr 12 18:16 /dev/cdrom -> sr //其實cdrom只是指向sr裝置的軟串連。

mount: block device /dev/sr0 is write-protected, mounting read-only

[root@zh888 yum.repos.d]# ls /mnt
