Centos Add Swap Space

Check Free Memory
free mem

Enable Swap
swapon -s

Add swap space
fallocate -l 4G /swapfile

Change owner to system
chmod 600 /swapfile

Make the swapfile
mkswap /swapfile

Enable the swapfile
swapon /swapfile

Your swapfile should be there

If you had problems with fallocate
Use dd instead

dd if=/dev/zero of=/swapfile count=4096 bs=1MiB

There you go!!
