18.8 " Linux Learning Is Not Difficult" File System Management ( 8 ): Set up to automatically mount the Linux file system at boot
It can only be used after a certain partition or device is mounted, but when the computer is restarted, it needs to be mounted again. At this time, the Linux file system can be automatically mounted on boot by modifying the /etc/fstab file. To automatically mount the file system at startup, you need to add information about the disk partition to the /etc/fstab file, which can be achieved by providing the device name and UUID.
1 . use device name
Edit the /etc/fstab file and add the following at the end of the file.
/dev/sda5 /mnt/www xfs defaults 1 2
2 . Using UUIDs
First use the following command to view the UUID information of the disk partition /dev/sda5.
[root@rhel ~]# ls -l /dev/disk/by-uuid
Total usage 0
lrwxrwxrwx. 1 root root 10 12月 26 14:56 500f998a-a4c9-43d8-b468-109a42787ec8 -> ../../sda2
lrwxrwxrwx. 1 root root 10 12月 26 14:56 b6d87c93-6c54-48f3-9295-ec0f7b92c9f3 -> ../../sda1
lrwxrwxrwx. 1 root root 10 12月 26 14:56 d8636446-9878-4437-b43c-50d71af8beba -> ../../sda3
lrwxrwxrwx. 1 root root 10 12月 26 15:02 f084b8a6-c9ab-425b-99da-b64cb35e4fc2 -> ../../sda5
// The UUID of disk partition /dev/sda5 is f084b8a6-c9ab-425b-99da-b64cb35e4fc2
Then edit the /etc/fstab file and add the following at the end of the file.
UUID= f084b8a6-c9ab-425b-99da-b64cb35e4fc2 /mnt/www xfs defaults 1 2
