$ cd /

$ sudo dd if=/dev/zero of=swapfile bs=1M count=3000

To set it as 1GB, change the count value (3000 in the example above) to 1000, 1500 for 1.5GB etc.

Now change the file created to a swap file with the command below.

$ sudo mkswap swapfile

Turn on the swap file with the command,

$ sudo swapon swapfile

To ensure that the swap file is turned on automatically at system startup, open fstab.

$ sudo nano etc/fstab

And add the line given below. Save and close.

/swapfile none swap sw 0 0

That is it. You can check if the system is using the swap file you created with the command

$ cat /proc/meminfo
