磁盘进行挂载一定是一个目录, 这个目录就是进入该磁盘分区的一个入口.
挂载命令 mount, 首先 man mount 查看技术文档.
mount - mount a filesystem 挂载文件系统
The standard form of the mount command, is mount -t type -o options device dir(标准语法)
-t type 表示: 指定要挂载的文件系统类型, ext2/ext3/ext4/vfat/iso9660...
-o options 表示: 额外的参数, 如 ro/rw,async/sync,auto/noauto...
device 表示: 是一个文件的名称或一个特殊的块设备, 比如 / dev/sda1, 也可能是一个特殊的 NFS 设备名称可能是 knuth.cwi.nl:/dir, 这样就需要使用它的 LABEL 或 UUID 进行自动 0 挂载.
dir 表示: 挂载的目录
mount 的选项
[root@www ~]# mount -V 查看版本信息
mount from util-linux-ng 2.17.2 (with libblkid and selinux support)
- [root@www ~]# mount -h 查看帮助信息
- Usage: mount -V : print version
- mount -h : print this help
- mount : list mounted filesystems
- mount -l : idem, including volume labels
So far the informational part. Next the mounting.
The command is `mount [-t fstype] something somewhere'.
Details found in /etc/fstab may be omitted.
- mount -a [-t|-O] ... : mount all stuff from /etc/fstab
- mount device : mount device at the known place
- mount directory : mount known device here
- mount -t type dev dir : ordinary mount command
Note that one does not really mount a device, one mounts
a filesystem (of the given type) found on the device.
One can also mount an already visible directory tree elsewhere:
mount --bind olddir newdir
or move a subtree:
mount --move olddir newdir
- One can change the type of mount containing the directory dir:
- mount --make-shared dir
- mount --make-slave dir
- mount --make-private dir
- mount --make-unbindable dir
One can change the type of all the mounts in a mount subtree
- containing the directory dir:
- mount --make-rshared dir
- mount --make-rslave dir
- mount --make-rprivate dir
- mount --make-runbindable dir
A device can be given by name, say /dev/hda1 or /dev/cdrom,
or by label, using -L label or by uuid, using -U uuid .
Other options: [-nfFrsvw] [-o options] [-p passwdfd].
For many more details, say man 8 mount .
- [root@www ~]# mount -v 冗长格式, 查看所有挂载的详细信息
- /dev/sda5 on / type ext4 (rw)
proc on /proc type proc (rw)
sysfs on /sys type sysfs (rw)
devpts on /dev/pts type devpts (rw,gid=5,mode=620)
- tmpfs on /dev/shm type tmpfs (rw)
- /dev/sda1 on /boot type ext4 (rw)
- /dev/sda2 on /usr type ext4 (rw)
- /dev/sdc4 on /home type ext4 (rw)
none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw)
L LABEL = 指定 label 进行挂载
U UUID 指定 UUID 进行挂载
常用命令:
[root@www ~]# mount -a 依据 / etc/fstab 文件信息进行挂载所有
