How to add SWAP Space in Linux

HelloJack / / Linux

Sometimes we need to add extra swap space in our Linux machine, so in this article, I’m going to show you how to add swap space to a Linux server.

We have two ways to adding swap space in Linux environment.

  1. Create swap space using the file.
free -m
swapon -s
dd if=/dev/zero of=/swap_file bs=1G count=1

chmod 600 /swap_file
mkswap /swap_file
vi /etc/fstab

/swap_file  		swap  			swap  	defaults  	0 0
swapon /swap_file 

2. Use Hard disk to adding swap space.

#fdisk -l
#swapon /dev/sdb1
#vi /etc/fstab

dev/sdb1 swap swap defaults 0 0 cat /etc/fstab swapon -s free -k
