Update swap memory ubuntu

Step 1 – Checking the System for Swap Information
sudo swapon --show
If you don’t get back any output, this means your system does not have swap space available currently.
You can verify that there is no active swap using the free
utility:
free -h
Step 2 – Checking Available Space on the Hard Drive Partition
df -h
Step 3 – Creating a Swap File
sudo fallocate -l 1G /swapfile
ls -lh /swapfile
ls -lh /swapfile
Step 4 – Enabling the Swap File
sudo chmod 600 /swapfile
ls -lh /swapfile
sudo mkswap /swapfile
sudo swapon /swapfile
sudo swapon --show
ls -lh /swapfile
sudo mkswap /swapfile
sudo swapon /swapfile
sudo swapon --show
We can check the output of the free
utility again to corroborate our findings:
free -h
Step 5 – Making the Swap File Permanent
sudo cp /etc/fstab /etc/fstab.bak
echo '/swapfile none swap sw 0 0' | sudo tee -a /etc/fstab
echo '/swapfile none swap sw 0 0' | sudo tee -a /etc/fstab
