Creating swapfile

source: https://www.digitalocean.com/community/tutorials/how-to-add-swap-on-ubuntu-12-04
  1. listing enabled swaps
    sudo swapon -s
    
  2. check available space
     df
    
  3. create swap file (the following will create 1GB swap, modify count if needed)
    sudo dd if=/dev/zero of=/swapfile bs=1024 count=1024k
    
  4. prepare the swap file by creating a linux swap area
    sudo mkswap /swapfile
    
  5. activate the swap file
    sudo swapon /swapfile
    
  6. ensure that the swap is permanent by adding it to the fstab file
    sudo nano /etc/fstab
    
    paste:
    /swapfile       none    swap    sw      0       0 
    
  7. set swappiness in the file to 10 so swap act as an emergency buffer
    echo 10 | sudo tee /proc/sys/vm/swappiness
    echo vm.swappiness = 10 | sudo tee -a /etc/sysctl.conf
    
  8. prevent the file from being world-readable
    sudo chown root:root /swapfile 
    sudo chmod 0600 /swapfile
