Dd if =/dev/zero of =/swapfile bs = 1 M count = 1024 # Create a 1g File
Mkswap swapfile # set the file type to swap
Swapon swapfile # use swap for mounting. it is only attached to the memory. if you want to start the system, modify/etc/fstab.

Free # view the swap space changes. The swap increases by 1 GB.
