实验01：访问光盘数据

• 实验目标

熟练linux光盘的安装

访问光盘的数据

• 实验步骤

[root@localhost ~]# umount /dev/cdrom

[root@localhost ~]# ls /media/

[root@localhost~]#

二．手动挂载

1.指定光盘安装位置

[root@localhost~]# mount /dev/cdrom /media/

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

2.测试

[root@localhost~]# mount | grep hdc

/dev/hdcon /media/RHEL_5.9 x86_64 DVD type iso9660 (ro,nosuid,nodev,uid=0)

/dev/hdcon /media type iso9660 (ro)

• 结果验证

[root@localhost~]# ls /media/
