SWAP File

If you have rented a weak server, this is the solution for you. It will not be superfluous to play it safe and increase the operational capabilities of the server. Text instructions are here.

If there is a possibility that you have ALREADY created a SWAP file, you need to check its existence.

sudo swapon --show

If the file does not exist, then proceed to create it.

sudo apt install fallocate -y
sudo fallocate -l 2G /swapfile
sudo chmod 600 /swapfile
sudo mkswap /swapfile
sudo swapon /swapfile

To make the change permanent, open and modify the fstab file:

sudo nano /etc/fstab

Let's insert the following line at the end of the file: /swapfile swap swap defaults 0 0

🎉Make sure the file is created and running:

sudo swapon --show
sudo free -h
