How To Add Swap on Ubuntu 14.04

Adding swap space to Ubuntu 14.04 can help improve system performance and prevent memory-related issues. Here's a step-by-step tutorial on how to do it:

  1. Check if you have any swap space by running the following command:
    2. sudo swapon -s
  2. Create a swap file of the desired size using the following command:
    3. sudo fallocate -l [size] /swapfile

    Replace [size] with the desired size of the swap file in megabytes (MB). For example, to create a 4GB swap file, use "sudo fallocate -l 4G /swapfile".

  3. Secure the swap file by setting appropriate permissions:
    4. sudo chmod 600 /swapfile
  4. Mark the file as swap space:
    5. sudo mkswap /swapfile
  5. Activate the swap file:
    6. sudo swapon /swapfile
  6. Verify that the swap space has been added:
    7. sudo swapon -s
  7. Make the swap file permanent by adding it to the fstab file:
    8. echo '/swapfile none swap sw 0 0' | sudo tee -a /etc/fstab

That's it! You've successfully added swap space to your Ubuntu 14.04 system.
