Creating Swap File

To add a swap file to your vps run the following as root

To add a 500mb swap file change count=500 to another number for a smaller or bigger swap file

# dd if=/dev/zero of=/var/swap2 bs=1024k count=500
# chown root:root /var/swap2
# chmod 700 /var/swap2
# mkswap /var/swap2
# swapon /var/swap2

To have the swap file used by the kernel after a reboot, add the following to /etc/fstab (its the same as running swapon)

/var/swap2       none    swap    sw      0       0
