swap space when installing phusion passenger

I tried to install Phusion Passenger and since I had less than 1GB free memory it recommended temporarily adding swap space with there commands:

sudo dd if=/dev/zero of=/swap bs=1M count=1024
sudo mkswap /swap
sudo swapon /swap

Passenger installed successfully so do I now have to disable that swap space - how? It didn't say anything about reverting but I think it should because it said "temporarily add swap space". How do I negate this effect now?

Solution 1:

It's up to you whether you want to disable it or not. If you do nothing else, it'll be gone if/when you reboot. If you want it permanent, you'll have to add it to /etc/fstab. If you do want to disable it:

sudo swapoff /swap
