This section provides the procedures for installing Linux manually on the management server.
The following topics are discussed:
Insert the RedHat Linux installation CD-ROM 1 of 4 in the DVD drive of the N1 System Manager management server and reboot the system.
At the boot: prompt, start either a text-based or graphical user interface-based installation.
Press Return to install using the graphical interface.
Type text to install using the text-based interface.
Respond to each prompt according to the requirements of your environment. You are prompted for the language selection, keyboard configuration, and mouse type. Provide the requested information.
When prompted for partitioning information, choose Automatically Partition.
You are prompted to choose whether to remove all Linux partitions, remove all partitions, or keep all partitions. Choose Remove all partitions. The partitioning values are displayed.
Compare the displayed values to the required values listed by Table 3–2.
If the partitioning values match, choose Next.
If the partitioning values do not match, update the partitioning values to match Table 3–2.
When prompted for the boot loader, choose Grub.
When prompted to provide the Ethernet port selections, assign the IP addresses, netmask, and gateway values as described in the following guidelines.
Configure ETH0 to connect to the corporate network to provide external access to the management server.
Configure ETH1 to connect to the provisioning network.
ETH1 must be on the same broadcast domain as ETH0. The IP addresses must be on the same broadcast domain as the provisionable servers' ETH0 interfaces, and can be configured to support hundreds of provisionable servers.
Configure ETH2 to connect to the management processor interface port (SP0) of all provisionable servers.
The netmask and gateway values must allow access to the management network.
If you have not installed a separate ETH2 gigabit NIC card in the management server, ETH0 and ETH2 functionality can be provided solely by ETH0. ETH0 must be configured to provide access to and from the management processor interfaces of the provisionable servers.
When prompted for the firewall configuration, choose No firewall.
You are prompted in sequence for additional language support, your time zone, and the root password. Provide the requested information.
When prompted to accept the default packages or to customize the set of packages to install, choose Customize.
Choose the packages required by the N1 System Manager system.
Engineering and Scientific
Legacy Software Development
Legacy Network Server
Compatibility Architecture Support (graphical install) or Legacy Software Development (text install)
When you have completed the package selection, continue the installation. When Linux installation completes, you are prompted for additional system information such as graphics, monitor type, and screen resolution after which the system reboots. You are then prompted for additional startup information.
Answer the System information prompts.
When you have completed responding to the prompts, the login screen appears.
Log in as root.
If you have installed RedHat Enterprise Linux 3.0 AS or ES Update 2 on the management server, install the additional RPMs required by the N1 System Manager as described in the next section, To Install RPMs Required by the N1 System Manager From the CD-ROMs.
Install the internationally compliant Perl module as described in Installing the Internationally Compliant Perl Module
Enable FTP as described in Enabling FTP on the Management Server.
Update the /etc/hosts file as described in Updating the /etc/hosts File.
Configure the mail service as described in Configuring the Management Server Mail Service and Account.
If you have installed RedHat Enterprise Linux 3.0 AS or ES Update 2 on the management server, you must also install the additional RPMs required by the N1 System Manager system.
Log in as root to the N1 System Manager management server.
Install the following RPMs from your RedHat installation CD-ROMs.
The location of the RPMs on the installation CD-ROMs varies depending on your RedHat Linux version.
A DSA signature:nokey warning is displayed during RPM installation. This warning message is generated only because the RPMs do not have a DSA security signature. All DSA signature:nokey warning messages can be safely ignored.
Download and install the internationally compliant Perl module as described in the next section.
