创建挂载目录/media/cdrom：
[root@CactiEZ ~]# mkdir /media/cdrom
临时挂载：
[root@CactiEZ cdrom]# mount /dev/cdrom /media/cdrom/
mount: block device /dev/sr0 is write-protected, mounting read-only设置开机自动挂载方法：

增加最后一行：

挂载文件 挂载目录 文件类型 默认 默认 默认小技巧：想知道文件类型，可以手动挂载后用mount命令即可查询
查看挂载成功的命令：mount
[root@CactiEZ cdrom]# mount
/dev/mapper/vg_cactiezv10-LogVol00 on / type ext4 (rw)
proc on /proc type proc (rw)
sysfs on /sys type sysfs (rw)
devpts on /dev/pts type devpts (rw,gid=5,mode=620)
tmpfs on /dev/shm type tmpfs (rw)
/dev/sda1 on /boot type ext4 (rw)
none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw)
/dev/sr0 on /media/cdrom type iso9660 (ro)
可以看到最后一行（这里就有文件类型）：
/dev/sr0 on /media/cdrom type iso9660 (ro)重启服务器查看是否挂载成功：
[root@CactiEZ cdrom]# reboot

成功挂载：
/dev/sr0 on /media/cdrom type iso9660 (ro)注意：/dev/cdrom和/dev/sr0是一个文件
[root@CactiEZ ~]# ll /dev/cdrom
lrwxrwxrwx 1 root root 3 Sep 19 10:09 /dev/cdrom -> sr0
好了，开机成功挂载文件目录
