Linux system mount operation Mount detailed

In Linux Systems, the file system is not mounted and cannot be used. Mount, which is to make the file system available in the operating system. The Mount command is used in Linux to mount the file system, with both persistent mounts and temporary mounts.

1. Permanent mount:

Modify the configuration file /etc/fstabtowrite the file system you want to mount in this configuration file, and then use the command

Mount-a Let the configuration information take effect, the mounted file can be used.

To/etc/fstab the contents of the configuration file, the circled line is the information we need to add.

Once mounted, you can use mount to view relevant information and use the command df-h to view the available partitions.

2. Temporary mounts:

MOUNT-T file format mount file mount directory

such as:mount-t ext3/dev/sdb1/opt

Then use the command mount-a to make the mount effective, and the mounted file can be used.

Note: Temporary mounted file systems are disabled when the operating system restarts and cannot be used.
