While increasing Swap File on the Server, first you need to check there should be enough free space (larger than new swap size) available on the partition.
Follow the below steps:
Step 1:- #dd if=/dev/zero of=/swapfile bs=1024 count=1572864 This command is for creating the free space for file /swapfile to 1.5 GB Please note that count is the block size calculated as (1024 * 1.5) Step 2:- #mkswap /swapfile Step 3:- #chown root:root /swapfile Step 4:- #chmod 0600 /swapfile1 Step 5:- #swapon /swapfile1 Step 6:- #vi /etc/fstab Enter this at the end of file "/swapfile1 swap swap defaults 0 0" Step 7:- # mount -a or Step 8:- free -m (check swap file size for your confirmation) Step 9:- This has been done Cheers !!!
