Linux how to use the mount command to mount CDROM, many novices are not very clear about this, in order to help you solve this problem, the following editor will explain in detail for you, people with this need can come to learn, I hope you can get something.

For example, use the mount command to mount cdrom

Command:

Mount-t auto / dev/cdrom / mnt/cdrom

The command is to mount the cdrom in the / mnt/cdrom directory, where I can access the contents.

Mount command:

Homer@ubuntu: ~ $mount-t auto / dev/cdrom / mnt/cdrom

Tip: mount: only root can do that / / ordinary users cannot mount cdrom, only root users can operate it.

Switch users:

Root@ubuntu: ~ # mount-t auto / dev/cdrom / mnt/cdrom

Mount: the mount point / mnt/cdrom does not exist / mnt/cdrom directory does not exist and needs to be created first.

Root@ubuntu: ~ # mkdir-p / mnt/cdrom / / Recursive create / mnt/ CDRom subdirectory

Remount:

Root@ubuntu: ~ # mount-t auto / dev/cdrom / mnt/cdrom / / Mount cdrom

Mount: block device / dev/cdrom is write-protected, mounting read-only / / mounted successfully

Root@ubuntu: ~ # ls-l / mnt/cdrom / / View the contents of cdrom

Uninstall command:

Root@ubuntu: ~ # umount / mnt/cdrom / / it's easy to uninstall cdrom. Use umount / mnt/cdrom directly.

Mount command other parameter name: mount

Rights of use: system administrator or users allowed in / etc/fstab

Mode of use:

Mount [- hV]

Mount-a [- fFnrsvw] [- t vfstype]

Mount [- fnrsvw] [- o options [,...]] Device | dir

Mount [- fnrsvw] [- t vfstype] [- o options] device dir

Description:

Interpret the contents of a file as a file system, and then hang it on a location in the directory. When this command is successfully executed, all files under this command will not be available for the time being until we remove the file system using umnount.

This command can be used to mount any file system, and you can even use the-o loop option to mount a general file as if it were a hard drive. This feature is very useful for interpreting ramdisk,romdisk or ISO 9660 video files.

Parameters:

-V display program version

-h display auxiliary message

-v displays more messages and is usually used with-f for debugging.

-a Mount all file systems defined in / etc/fstab.

The command-F is usually used with-a, which generates a stroke for each mount action to be executed. When the system needs to hang a large number of NFS file system, you can speed up the action of hanging.

-f is usually used for debugging purposes. It causes mount not to perform the actual mount action, but to simulate the entire mount process. Usually used with-v.

-n generally speaking, mount will write a piece of data in / etc/mtab after hanging up. However, you can use this option to cancel this action if there is no writable file system in the system.

-smurr equals-o ro

-w equals-o rw

-L hangs the hard drive with a specific label on it.

-U hangs up the file system with the file division serial number. -L and-U only make sense when files such as / proc/partition exist.

-t specifies the type of file system, which is usually not required. Mount automatically selects the correct type.

-o async turns on asynchronous mode, and all file read and write actions are performed in asynchronous mode.

-o sync executes in synchronous mode.

-o atime

-o noatime when atime is opened, the last call time of the archive is updated each time the archive is read. When we use the flash file system, we may choose to turn this option off to reduce the number of writes.

-o auto

-o noauto toggles auto hang mode on / off.

-o defaults uses the default options rw, suid, dev, exec, auto, nouser, and async.

-o dev

-o nodev-o exec

-o noexec allows executable files to be executed.

-o suid

-o nosuid allows execution files to be executed under root permissions.

-o user

-o nouser users can perform mount/umount actions.

-o remount remounts a suspended file system in a different way. For example, a system that used to be read-only is now re-hung in read-write mode.

-o ro hangs in read-only mode.

-o rw hangs in read / write mode.

-o loop= uses loop mode to attach a file to the system as if it were a hard disk partition.

Example:

Hang / dev/hda1 under / mnt.

# mount / dev/hda1 / mnt

Hang / dev/hda1 under / mnt in read-only mode

# mount-o ro / dev/hda1 / mnt

Hang the image file of the CD / tmp/image.iso under / mnt/cdrom using loop mode

In this way, the contents of Linux ISO files that can be found on the network can be viewed without burning them into CDs.

# mount-o loop / tmp/image.iso / mnt/cdrom
