[root@localhost root]# mount /mnt/cdrom
mount: wrong fs type, bad option, bad superblock on /dev/cdrom,
or too many mounted file systems
[root@localhost root]#
而且无法运行unmount
[root@localhost root]# unmount
bash: unmount: command not found
请问是什么原因?

你的命令打错了,mount不但要有挂载点,还要有源,比如 mount -t iso9660 /dev/cdrom /mnt/cdrom
没有unmount,只有umount。
另外,umount也要指定目标,如 umount /dev/cdrom,不能直接使用umount,自己用man mount 好好看看。
