6.1.2 Prepare the Build-Up Installation

The following procedure was used to create the custom media to install the build-up system.

The customization included configuring a default kickstart for the media and creating a

resources directory containing files to be used in the configuration.

1. Download the released Red Hat Enterprise Linux 5.5 DVD via the RHN home page

• Select Download Software on the left side of the page

• Select the link for Red Hat Enterprise Linux (v. 5 for 64-bit x86_64)

• Select the Binary DVD (Server Core/Cluster/Cluster Storage/Virtualization) link

2. Duplicate the media

a) Create a directory for mounting the media

mkdir -p /pub/projects/cloud/resources/wa/mnt

b) Mount the media

mount -o loop /pub/kits/rhel-server-5.5-x86_64-dvd.iso \

/pub/projects/cloud/resources/wa/mnt

c) Create directory for copying the media

mkdir -p /pub/projects/cloud/resources/wa/r55

d) Copy the expanded media

cd /pub/projects/cloud/resources/wa/mnt; tar -cf - . | \

(cd /pub/projects/cloud/resources/wa/r55; tar -xvpf -)

e) Unmount the original media

umount /pub/projects/cloud/resources/wa/mnt

3. Modify the duplicate tree

a) Create the kickstart file /pub/projects/cloud/resources/wa/r55/ks.cfg that:

• installs and configures the system

• copies the entire media to the installed system

• sets the time and prepare NTP to start

• registers the machine with RHN

• prepares the NFS export of the installation media and customization

• configures iptables (firewall)

• converts the public network to a bridge named cloud0

• disables LRO

• prepares the actions to be performed on next boot
