How can I increase the swap partition in Linux?

To increase the swap partition of Linux, you can follow these steps:

1. Check if there is an existing swap partition in the current system. You can use the following command to check the status of the swap partition:

sudo swapon --show

If there are no displayed swap partitions, it means that there are no swap partitions in the current system.

1. Create a file for swapping partitions. You can use the following command to create a swap partition file (for example, 4GB):

sudo fallocate -l 4G /swapfile

1. Set the file permissions to only allow the root user to read and write.

sudo chmod 600 /swapfile

1. Convert the file into a swap partition.

sudo mkswap /swapfile

1. Enable swap partition.

sudo swapon /swapfile

1. Check if the swap partition is enabled.

sudo swapon --show

The newly added swap partition should be visible.

1. To enable the swap partition to automatically start at system boot, you need to add it to the /etc/fstab file. Open the file:

sudo nano /etc/fstab

Add the following lines at the end of the file.

/swapfile none swap sw 0 0

Save and close the file.

After completing the above steps, the partition swap has been successfully added to the Linux system.
