We will see how to create a swap zone in a file.

This can also be used to complement an existing swap area as a partition or file.

Example to add 1GB of swap to the swapfile1 file in the root.

We generate the file :

# dd if=/dev/zero of=/swapfile1 bs=1024 count=1048576

Format the file in swap:

# mkswap /swapfile1 1048576

Mount the area of swap:

# swapon /swapfile1

We add the following configuration to the /etc/fstab file so that the swap zone is mounted at startup:

/swapfile1 swap swap defaults 0 0
