Here are the steps I took to enable swap space

sudo dd if=/dev/zero of=/swapfile bs=1M count=512
sudo mkswap /swapfile
sudo chmod 600 /swapfile
sudo swapon /swapfile

You also have to edit your fstab file so the swap is available after reboot

sudo vi /etc/fstab

Add the following to the bottom of the file – I made sure it lined up with the existing entries, but that’s probably not necessary.

/swapfile swap swap defaults 0 0
