Sun N1 System Manager 1.2 Site Preparation Guide

Installing the RedHat Linux OS Using Kickstart

This section provides example Kickstart files and the procedures to configure a Kickstart file and then use the Kickstart file to install Linux.

Sample Kickstart Files

This section provides two example Kickstart files. The first Kickstart file shown in Example 3–2 is configured for a full distribution installation of Linux. The second Kickstart file shown in Example 3–3 is configured to install only the RPM groups required by the N1 System Manager.

ProcedureTo Configure the Kickstart File

Steps

  1. Log in to a machine that is accessible to the management server using NFS or HTTP.

  2. Create the Linux Kickstart configuration file.

    Choose whether to use the entire distribution Kickstart file shown in Example 3–2, or the required-RPMs-only Kickstart file shown in Example 3–3. Copy the chosen configuration data into a file, for example, n1gc-ks.cfg.

    Note –

    If you chose the required-RPMs-Kickstart file, you must also manually install additional RPMs as described in To Install RPMs Required by the N1 System Manager From the CD-ROMs.

  3. Configure the Kickstart installation file for your environment.

    • If you plan to use dynamic IP addressing, replace each network statement in the Kickstart file using the following syntax:

      network --device ethx --bootproto dhcp

      where ethx is the port, for example, eth0.

    • If you plan to use static IP addressing, make the following changes in each of the network statements.

      • Replace ip with the Ethernet port IP address.

      • Replace nameserver with the IP address of the corporate name server. If you want to use more than one name server, separate each name server IP address with a comma. For example: --nameserver 110.112.113.11,110.112.113.22.

      • Replace hostname with the name of your management server.

      If desired, you can combine static and dynamic IP addressing for the ETH ports. Modify the network settings according to your chosen reference architecture.

  4. Save the Kickstart file to an NFS or HTTP directory on the Kickstart server.
