Create a swap file to let OS use when the physical memory is not big enough. Make the swap file as 1~2x big as your physical memory.
CreateSwap.sh:
#!/usr/bin/env bash
fallocate -l 12G /swapfile
chmod 600 /swapfile
mkswap /swapfile
swapon /swapfile
echo "/swapfile swap swap defaults 0 0" >> /etc/fstab
Then use swapon --show to check current swaps.
If your system already configured other swaps, you can use swapoff to remove it, for example:
swapoff /dev/sdb
Also remember to remove it in the /etc/fstab file such that it won't get used when system rebooted next time.
