18.2.3 Creating and Using a Swap Partition

To create and use a swap partition:

Use fdisk to create a disk partition of type 82 (Linux swap) or parted to create a disk partition of type linux-swap of the size that you require.
Initialize the partition (for example, /dev/sda2) as a swap partition:
```
# mkswap /dev/sda2
```
Enable swapping to the swap partition:
```
# swapon /swapfile
```
Add an entry to /etc/fstab for the swap partition so that the system uses it following the next reboot:
```
/dev/sda2       swap       swap       defaults       0 0
```
