Linux automatically mounts disk partitions based on UUID

The general server has multiple hard disk partitions, which may change when the logical location of these partitions is loaded after a reboot, and may cause confusion due to changes in disk order if the disk is mounted using traditional device names (for example:/DEV/SDA).

Each block device in the Linux environment has a globally unique UUID that identifies the device, and we can replace the device name with a UUID in the fstab so that this confusion does not occur.

　　

1. Take SDB1 as an example, first use the LSBLK command to get a clear picture of the global block device layout

　　

2. Then use the Blkid command to get the device's UUID. Copy Note SDB1 's UUID

　　

3.VI editing/etc/fstab File System Information

4. Add a line at the end. Then: Wq Save exit

5. After rebooting, Df-h can see that the SDB1 has been loaded automatically.
