2.1. OS Installation

Detailed instructions for installing Fedora are available at in a number of languages. The abbreviated version is as follows…
Point your browser to, locate the Install Media section and download the install DVD that matches your hardware.
Burn the disk image to a DVD [4] and boot from it. Or use the image to boot a virtual machine as I have done here. After clicking through the welcome screen, select your language and keyboard layout [5]

Assign your machine a host name. [6] I happen to control the domain name, so I will use that here.

You will then be prompted to indicate the machine’s physical location and to supply a root password. [7]
Now select where you want Fedora installed. [8]
As I don’t care about any existing data, I will accept the default and allow Fedora to use the complete drive. However I want to reserve some space for DRBD, so I’ll check the Review and modify partitioning layout box.
Choose Install Type

By default, Fedora will give all the space to the / (aka. root) partition. Wel’ll take some back so we can use DRBD.
Default Partitioning

The finalized partition layout should look something like the diagram below.


If you plan on following the DRBD or GFS2 portions of this guide, you should reserve at least 1Gb of space on each machine from which to create a shared volume. Fedora Installation - Customize PartitioningFedora Installation: Create a partition to use (later) for website data

Unless you have a strong reason not to, accept the default bootloader location

Next choose which software should be installed. Change the selection to Web Server since we plan on using Apache. Don’t enable updates yet, we’ll do that (and install any extra software we need) later. After you click next, Fedora will begin installing.

Once the node reboots, follow the on screen instructions [9] to create a system user and configure the time.

Creating a new user, take note of the password, you'll need it soon

It is highly recommended to enable NTP on your cluster nodes. Doing so ensures all nodes agree on the current time and makes reading log files significantly easier. Fedora Installation - Date and TimeFedora Installation: Enable NTP to keep the times on all your nodes consistent

Click through the next screens until you reach the login window. Click on the user you created and supply the password you indicated earlier.
Click here to configure networking

Do not accept the default network settings. Cluster machines should never obtain an ip address via DHCP. Here I will use the internal addresses for the network.
Specify network settings for your machine, never choose DHCP

Click the big green button to activate your changes
