linux挂载命令mount及U盘、移动硬盘的挂载

一.mount的命令格式是（注意mount只能在root权限下运行）

mount dervice dir

dervice是要挂载的设备，dir是挂载点

二.查看当前磁盘列表的设备

fdisk -l

显示如下信息

root@kali:~# fdisk -l
Disk /dev/sda: 465.8 GiB,  bytes,  sectors
Units: sectors of  *  =  bytes
Sector size (logical/physical):  bytes /  bytes
I/O size (minimum/optimal):  bytes /  bytes
Disklabel type: dos
Disk identifier: 0x1eb9aaf8

Device     Boot     Start       End   Sectors   Size Id Type
/dev/sda1  *              100G   HPFS/NTFS/exFAT
/dev/sda2          .8G  f W95 Ext'd (LBA)
/dev/sda5            122G   HPFS/NTFS/exFAT
/dev/sda6            122G   HPFS/NTFS/exFAT
/dev/sda7          .8G   HPFS/NTFS/exFAT

Disk /dev/sdb: 117.9 GiB,  bytes,  sectors
Units: sectors of  *  =  bytes
Sector size (logical/physical):  bytes /  bytes
I/O size (minimum/optimal):  bytes /  bytes
Disklabel type: dos
Disk identifier: 0x19ac4874

Device     Boot     Start       End   Sectors   Size Id Type
/dev/sdb1  *            .9G  Linux
/dev/sdb2                4G   Extended
/dev/sdb5                4G  Linux swap / Solaris

Disk /dev/sdc: 29.7 GiB,  bytes,  sectors
Units: sectors of  *  =  bytes
Sector size (logical/physical):  bytes /  bytes
I/O size (minimum/optimal):  bytes /  bytes
Disklabel type: dos
Disk identifier: 0x00000000

Device     Boot Start      End  Sectors  Size Id Type
/dev/sdc1           .7G  c W95 FAT32 (LBA)

这里我们可以看到所有连接在电脑上的设备和分区情况，比如我们想挂载/dev/sda5

三.创建挂载点

mkdir /mnt/diskd
mount /dev/sda5 /mnt/diskd

挂载成功

四.弹出设备

umount /dev/sda5

通过df可以查看设备挂载点
