ADDING SWAP TO AWS EC2 INSTANCE + MEMORY ALLOCATION PROBLEM

-

Adding Swap to Aws EC2 instance:-

sudo /bin/dd if=/dev/zero of=/var/swap.1 bs=1M count=1024
sudo /sbin/mkswap /var/swap.1
sudo chmod 600 /var/swap.1
sudo /sbin/swapon /var/swap.1

If you need more than 1024 then change that to something higher.

To enable it by default after reboot, add this line to /etc/fstab:

swap        /var/swap.1 swap    defaults        0   0

To turn ON the swap do the following:

swapon -a

To turn off the swap do the following:

swapon -a

To turn off the swap do the following:

sudo /sbin/swapoff /var/swap.1
