Provisioning HowTo

This option is already included in the wizard style kickstarts, but you may want to include it in the raw

kickstarts you create yourself.

If you would like more information about Cheetah and the constructs that can be used for writing

kickstart templates, the Cheetah User's Guide should be very helpful:

8. Kickstarting a Machine

8.1. Bare Metal

Satellite provides three mechanisms by which you can provision bare metal machines — machines

that have no operating system or that have the wrong operating system installed:

1. Boot Anaconda-style operating system installation disk

2. PXE boot

3. Boot Cobbler boot disk

8.1.1. Booting from an Anaconda Style Installation Disk

Simply boot the selected system using an installation disc that matches your kickstart. For example, if

your kickstart was configured to use the ks-rhel-i386-server-5-u2 kickstart tree, you must boot

with the Red Hat Enterprise Linux 5.2 i386 installation disc. When the boot prompt comes up, simply

type:

linux ks=http://satellite.example.com/path/to/kickstart

The system will boot, download the kickstart, and re-install itself.

8.1.2. PXE Booting

PXE booting is a very convenient method of installing and reinstalling your physical systems, but does

come with a few requirements:

• You must have a DHCP server, even if your systems are to be configured statically after installation.

• As DHCP does not normally cross network (router) boundaries, you will need to make special

provision to ensure that all of your machines can connect to your dhcp server(s) in the event your

machines reside on multiple networks. Options here include multi-homing your DHCP server

(either real or trunked vlan) and configuring your routers or switches to pass DHCP across network

boundaries.

• You must be able to configure your DHCP server to point to the PXE server (the Satellite server), by

setting the next-server address for the systems you want to be managed by Satellite.

• Each system you have must support PXE booting at the BIOS level. Nearly all recent hardware

should be able to do this.
