Cisco Cisco Prime Central 1.2 Installation Guide

To install RHEL 6.2, complete the following steps in parallel on both nodes, except where noted:

Configure specialized storage devices, high availability, and virtualization. See the Red Hat documentation for 
instructions.

Verify that the following options are checked:

Virtualization: Virtualization Tools

High Availability: High Availability

Desktops: General Purpose Desktop

Desktops: X Window System

Create local directories named /rhel and /cdrom-6.2.

Copy the .iso file that was used for the node installation to the /rhel directory.

Mount the /rhel .iso file to /cdrom-6.2:

# cd /rhel

# mount -t iso9660 -o loop /rhel/rhel-server-6.2-x86_64-dvd.iso /cdrom-6.2

To permanently mount the drive, update the /etc/fstab file. See 

Create a file named /etc/yum.repos.d/local.repo. Use UNIX format and be sure there are no spaces before lines.

Save the newly created file in local.repo, as follows:

[local]

name=Red Hat Enterprise Linux $releasever - $basearch - Local

baseurl=file:///cdrom-6.2/Server

enabled=1

gpgcheck=0

gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release

[HighAvailability]

name=Red Hat Enterprise Linux $releasever - $basearch - HighAvailability

baseurl=file:///cdrom-6.2/HighAvailability

enabled=1

gpgcheck=0

gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release

[ResilientStorage]

name=Red Hat Enterprise Linux $releasever - $basearch - ResilientStorage

baseurl=file:///cdrom-6.2/ResilientStorage

enabled=1

gpgcheck=0

gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release

(Optional) If you forget the HA package and want to install it later, enter:

# yum groupinstall "High Availability"

(Optional) If you forget the desktop and want to install it later, enter:

# yum groupinstall "X Window System" Desktop

# vi /etc/inittab

Then, change id:3:initdefault: to id:5:initdefault: and reboot the server.

Temporarily disable the firewall and SELinux to enable initial testing of the cluster:
