How to create swap in vps

Setup SWAP

It is required especially on a system with limited memory. I am setting up a 4GB swap, which may be overkill but it’s the most common swap sized used in most guides so ill keep it at that.

dd if=/dev/zero of=/mnt/myswap.swap bs=1M count=4000

mkswap /mnt/myswap.swap

swapon /mnt/myswap.swap

Now let’s add it into fstab so it’ll activate at boot.

nano /etc/fstab

Add the following line at the end of the file.

Quote:

 /mnt/myswap.swap none swap sw 0 0

Should look like this:

Ctrl+O to save, and Ctrl+X to exit the nano editor.

Now your swap is setup.
