linux下如何优雅的挂载一个外界设备(比如优盘)
最近从事linux,实验室一个破服务器,能连上网,但是输入这样的命令: yum -y install gcc
yum -y install gcc-c++ ,居然说是没有这样的镜像,也罢,就用U盘搞了一个linux gcc,gcc-c++,然后问题来了?
外挂哪家强? 完全找不到移动设备有木有。 嗷嗷的哭呀!
果断的敲入: fdisk -l -->查看分区的状态
Disk /dev/sdb: 4051 MB, 4051697664 bytes
151 heads, 42 sectors/track, 1247 cylinders
Units = cylinders of 6342 * 512 = 3247104 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0xc3072e18
Device Boot Start End Blocks Id System
/dev/sdb1 1 1248 3956708 c W95 FAT32 (LBA)
找到了,U盘的位置,但是就是进不去呀!
于是先建立一个路径: mkdir mnt/usb
有木有,果然的去问了迅雷工作的学长韦回超学长,说是我mount命令用错了!!
我看了,我的命令一下:mount /dev/gdb1/mnt/usb
并mount -help了一下!
恩! 是的! 用错了! 少了一个空格!! mount file1 file2
mount /dev/gdb1 /mnt/usb
这样就挂载好了!
总结一下步骤吧!:
第一步: fdisk -l -->查看外界设备的位置 比如这个优盘 /dev/sdb1
[root@tomato2 ~]# fdisk -l
Disk /dev/sda: 500.1 GB, 500107862016 bytes
255 heads, 63 sectors/track, 60801 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Disk /dev/mapper/vg_tomato2-lv_swap: 3388 MB, 3388997632 bytes
255 heads, 63 sectors/track, 412 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

255 heads, 63 sectors/track, 53797 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Disk /dev/sdb: 4051 MB, 4051697664 bytes
151 heads, 42 sectors/track, 1247 cylinders
Units = cylinders of 6342 * 512 = 3247104 bytes

Disk identifier: 0xc3072e18
Device Boot Start End Blocks Id System
/dev/sdb1 1 1248 3956708 c W95 FAT32 (LBA)
第二步: 设置一个路径 mkdir mnt/usb -->这个usb什么的就随便的起名字了!
[root@tomato2 ~]# mkdir /mnt/usb
第三步: 将U盘挂载到这个路径中来! mount /dev/gdb1 /mnt/usb
这样就ok 了! 但是最后还是有一个结尾就是卸载这个挂载点 unmount /mnt/usb
[root@tomato2 ~]# umount /mnt/usb
然后删除路径: rmkdir mnt/usb
[root@tomato2 ~]# rmdir /mnt/usb
然后就可以去优雅的去使用U盘里的东西啦!!!!
