Creer Une partition Swap apres install

Si je veux ajouter 4Go :

sudo fallocate -l 4G /swapfile STEP 4: SWAP file is created. Let’s give root-only permissions to it.

sudo chmod 600 /swapfile

STEP 5: Mark the file as SWAP space:

sudo mkswap /swapfile

STEP 6: Finally enable the SWAP.

sudo swapon /swapfile

STEP 7: You can now check using the same swapon command to check if SWAP is created.

sudo swapon --show

STEP 8: Also recheck the final partition structure.

free -h

STEP 9: Once everything is set, you must set the SWAP file as permanent, else you will lose the SWAP after reboot. Run this command:

echo '/swapfile none swap sw 0 0' | sudo tee -a /etc/fstab
