Make swap space on linux server

To create and add swap to a server..

If you have a spare disk or partition already just make it to swap like so:

mkswap /swap

If you don't have such a partition already you can use a file..

dd if=/dev/zero of=/swap bs=1024 count=1000000

Change "/swap" can be whatever you want to call it. Once created, use the mkswap command as above.

Then to enable the swap: swapon /swap

To disable: swapoff /swap
