If you decide to change the swap file size, then following the steps:
Turn the Swap Off
1 | swapoff -a |
swapoff -a
Resize the current Swapfile
The following resizes the swapfile to 1GB (1M x 1024)
1 2 3 4 | dd if=/dev/zero of=/swapfile bs=1M count=1024 1024+0 records in 1024+0 records out 1073741824 bytes (1.1 GB) copied, 4.22595 s, 254 MB/s |
dd if=/dev/zero of=/swapfile bs=1M count=1024 1024+0 records in 1024+0 records out 1073741824 bytes (1.1 GB) copied, 4.22595 s, 254 MB/s
Make it a Swapfile
1 2 3 | mkswap /swapfile Setting up swapspace version 1, size = 1048572 KiB no label, UUID=435cec7d-6c20-45c8-bd96-55e60ddf |
mkswap /swapfile Setting up swapspace version 1, size = 1048572 KiB no label, UUID=435cec7d-6c20-45c8-bd96-55e60ddf
Turn back on the Swapfile
1 | swapon /swapfile |
swapon /swapfile
Confirm it is On
You can verify the size change by using command free -h or htop.

Make sure this is added to /etc/fstab so when system reboots, the swapfile is turned on automatically.
