Step 1: Checking Existing Swap Space (Optional)
#

Before proceeding with creating a new swap file, it’s advisable to check if your VPS already has active swap space. Open a terminal and run the following command:

sudo swapon --show

If there is no output, your VPS likely doesn’t have active swap space, making it an ideal candidate for creating a new swap file.
Step 2: Creating the Swap File
#

To create a 2GB swap file, follow these steps:

    Connect to your VPS via SSH.

    Execute the following command to create a 2GB swap file (you can adjust the size as needed):

sudo fallocate -l 2G /swapfile

    Set appropriate permissions for the swap file:

sudo chmod 600 /swapfile

    Prepare the swap file:

sudo mkswap /swapfile

Step 3: Enabling the Swap File
#

Once the swap file is created, enable it with the following command:

sudo swapon /swapfile
