首先，要确保ISO被加载到了光驱中：

在Linux中mount一个ISO_linux mount /etc/fst 

查看当前系统中的文件系统使用情况：

  1. [root@RHEL ~]# df -h  
  2. Filesystem            Size  Used Avail Use% Mounted on 
  3. /dev/mapper/VolGroup00-LogVol00  
  4.                        18G  4.1G   13G  25% /  
  5. /dev/sda1              99M   13M   81M  14% /boot  
  6. tmpfs                 500M     0  500M   0% /dev/shm  
  7. [root@RHEL ~]# 

当前没有ISO被挂载到FS中。

配置文件系统的关联文件（/etc/fstb）：

  1. [root@RHEL ~]# cat /etc/fstab   
  2. /dev/VolGroup00/LogVol00 /                       ext3    defaults        1 1  
  3. LABEL=/boot             /boot                   ext3    defaults        1 2  
  4. tmpfs                   /dev/shm                tmpfs   defaults        0 0  
  5. devpts                  /dev/pts                devpts  gid=5,mode=620  0 0  
  6. sysfs                   /sys                    sysfs   defaults        0 0  
  7. proc                    /proc                   proc    defaults        0 0  
  8. /dev/VolGroup00/LogVol01 swap                    swap    defaults        0 0  
  9. /dev/cdrom      /iso            iso9660 defaults    0 0  
  10. [root@RHEL ~]# 

应用配置：

  1. [root@RHEL ~]# mount -a  
  2. mount: block device /dev/cdrom is write-protected, mounting read-only 
  3. [root@RHEL ~]# 

再次查看文件系统的状态：

  1. [root@RHEL ~]# df -h  
  2. Filesystem            Size  Used Avail Use% Mounted on 
  3. /dev/mapper/VolGroup00-LogVol00  
  4.                        18G  4.1G   13G  25% /  
  5. /dev/sda1              99M   13M   81M  14% /boot  
  6. tmpfs                 500M     0  500M   0% /dev/shm  
  7. /dev/hdc              3.9G  3.9G     0 100% /iso  
  8. [root@RHEL ~]# 

光盘介质（/dev/hdc）已经被成功挂在到了/iso下面。

看看光盘（ISO）中有些什么：

  1. [root@RHEL ~]# ls /iso
