Installing servers using your own PXE boot environment


Installing servers using your own PXE boot environment



Leaseweb offers customers to install a dedicated server using their own PXE boot environment. This way an installation can be performed with specific Operating System versions that Leaseweb currently does not offer or OS versions that are customized.


Leaseweb uses an DHCP/iPXE boot environment to install dedicated servers. We provide the option for customers to list, create and delete their own DHCP leases. With creating the leases it is possible to send your own boot file name using the API or Customer Portal, as well as boot server details (DHCP option 66 and 67) and DNS server IP address.

This way it is possible to hook your Leaseweb dedicated server to any automated installation platform (like TheForeman, FAI, Cobbler and others). Leaseweb provides the network details, although optionally you can set your own nameserver(s) to use during installation. In all cases the primary public IPv4 address of your server is automatically used.

Or you can click Custom Installation under Actions on your server's management page in the Customer Portal:

When you reboot your server, the DHCP server will instruct your bare metal server to boot using that boot file name.
