We can change this by adding the swap file to our /etc/fstab file.
Back up the /etc/fstab file in case anything goes wrong:
sudo cp /etc/fstab /etc/fstab.bak
You can add the swap file information to the end of your /etc/fstab file by typing:
echo '/swapfile none swap sw 0 0' | sudo tee -a /etc/fstab
cat /proc/sys/vm/swappiness
