linux外接光驱下载文件,Linux 从光驱拷贝文件以及加载新的硬盘

-------------------------------------------------------加载光驱---------------------------------------

1.将ISO文件放到光盘中，点击确定;

2.连接光驱

如果是虚拟机：菜单VM--&gtsetting--&gtHardware--&gt选CD/DVD--&gtConnection

3.将光驱加载到一个目录下，要先mount

[root@lvs-dr1 install]# mkdir /mnt/cdrom[root@lvs-dr1 install]# ls -l /dev/cdromlrwxrwxrwx 1 root root 3 Jan 12 13:58 /dev/cdrom -> hdc

[root@lvs-dr1 install]# mount /dev/cdrom /mnt/cdrom

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

[root@lvs-dr1 install]# mount /dev/hdc /mnt/cdrom

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

mount: /dev/hdc already mounted or /mnt/cdrom busy

mount: according to mtab, /dev/hdc is already mounted on /mnt/cdrom

4.拷贝数据到新的目录

[root@lvs-dr1 install]# cp /mnt/cdrom /tmp[root@lvs-dr1 tmp]# ls

然后就可以使用光驱中的问价年了

5.取消加载目录，要先unmount

[root@lvs-dr1 install]# unmount /dev/cdrom

6.退出光驱

[root@lvs-dr1] reject
