1. First, create a partition, using dd command, such as

dd if=/dev/zero of=/home/swap bs=1024 count=512000

Note: This creates a partition file called/home/swap. The size of the file is 512000 blocks. Generally, 1 block is 1K, so the space here is 512M.

2. Then turn this partition into a swap partition.

/sbin/mkswap /home/swap

3. Then use this swap partition. Make it valid.

/sbin/swapon /home/swap

4. Modify the/etc/fstab file to change the newly added swap partition to autostart and add the following line

vi /etc/fstab

/home/swap swap swap defaults 0 0
