Installing red hat linux
This chapter provides information about manually installing Red Hat Enterprise Linux on a Sun Fire X4140, X4240, or X4440 server. It contains the following sections:
To Mirror Your OS
| Note — If you want to mirror your OS, the recommended procedure is to create a hardware RAID before you install the OS. |
If you are using an Adaptec-based Sun StorageTek SAS RAID Internal HBA (PCIe card), see Appendix A.
If you are using an LSI-based Sun StorageTek PCI Express SAS 8-Channel HBA ( SG-XPCIE8SAS-I-Z ) that controls internal disks, see Appendix B.
If you are using an LSI-based Sun StorageTek PCI Express SAS 8-Channel HBA ( SG-XPCIE8SAS-E-Z ) that controls external disks, RAID is not available.
| Note — If you use the Sun Installation Assistant to install Red Hat Enterprise Linux, the only sections of this chapter that you will need are: Preconfiguring Your Network to Support PXE Installation of RHEL and Updating a RHEL OS. |
If you have installed Red Hat Enterprise Linux (RHEL) software on other AMD Opteron servers, you are already familiar with how to install it on a Sun Fire X4140, X4240, or X4440 server. The most common methods to install RHEL on your server are to use:
The RHEL distribution media
The automatic kickstart installation from RHEL software (installation tree) stored on a Preboot Execution Environment (PXE) network server
| Note — The Sun Installation Assistant is a convenient, front-end application designed to assist you in installing Red Hat Enterprise Linux on your server. The Sun Installation Assistant supplements the standard installation utilities and procedures that ship with Red Hat Enterprise Linux; it does not replace them. Refer to Using the Sun Installation Assistant (SIA) for more information. |
Red Hat Installation and Administration Documentation
Before you install the RHEL software on a Sun Fire X4140, X4240, or X4440 server, consult the following RHEL documentation.
, and AMD64 Architectures at: http://www.redhat.com/docs/manuals/enterprise/ 
To Install RHEL From Local Media| Note — Read the Integrated Lights Out Manager (ILOM) Administration Guide before completing the following steps. This guide provides details on using the ILOM service processor web interface to redirect the console. |
To Install Using the ILOM Remote Console Application
1. Locate your RHEL installation CD/DVD or the equivalent ISO images.
2. Connect to the ILOM Service Processor Web interface.
3. Click the Remote Control tab, then the Mouse Mode Settings tab.
4. If necessary, change the mouse mode to Relative Mouse Mode.
See the “Remote Console Application” chapter of the Integrated Lights Out Manager (ILOM) Administration Guide for further instructions.
5. Click the Redirection tab.
6. Click the Launch Redirection button to start the JavaRConsole application.
7. Log in to the JavaRConsole.
8. Start keyboard and mouse redirection.
Select Keyboard and Mouse in the Devices menu.
9. Start CD/DVD redirection.
From the JavaRConsole Devices menu, you can redirect the CD several ways:
CD-ROM —If you are installing a physical CD into the remote console CD ROM drive, insert the CD into the drive and select CD-ROM.
ISO Image —If you are using an ISO image installed on the remote console, select CD-ROM image and provide the location of the iso file.
| Note — Floppy diskette redirection is also available through the JavaRConsole. See the Integrated Lights Out Manager (ILOM) Administration Guide for more details. |
10. Turn on the server using the ILOM Web interface.
11. Set up the BIOS as follows:
a. Press Ctrl-E to enter the BIOS Setup utility.
b. Select the Boot menu.
c. Select CD/DVD Drives.
d. Set AMI Virtual CD as the first boot device.
e. Press F10 to save changes and exit.
f. Reboot the server.
g. Press Ctrl-P to select CD/DVD as the boot device.
12. When the boot prompt appears, enter linux text .
13. When prompted to test the CD media before installation, select Skip if you do not want the media test to run.
14. Refer to the Red Hat Enterprise Linux Installation Guide to guide you through the remainder of the installation process.
The on-board network interface card (NIC) in your Sun Fire X4140, X4240, or X4440 server supports the Preboot Execution Environment (PXE) network booting protocol. The system BIOS and network interface BIOS on your server automatically query the network for a DHCP server. If the DHCP server on the network has been configured to support the PXE protocol and PXE image servers on the same network, then the BIOS on your system can be used to install a bootable Red Hat Enterprise Linux (RHEL) image on your server.
| Tip — PXE is a powerful and convenient solution for setting up a number of your Sun Fire X4140, X4240, or X4440 servers so that their configuration is identical. |
 | Caution — On the chassis, Ethernet ports are labeled NICi (i = 0,1,2,3). Linux internally represents Ethernet ports as ethj (j = 0,1,2,3). Labeling implies NICi -> ethj, where i=j. This is generally true, but for the for Sun Fire X4140, X4240, or X4440 servers the mapping is as follows: |
NIC0 -> eth2
NIC1 -> eth3
NIC2 -> eth0
NIC3 -> eth1
Task Map
If you don’t have PXE set up on your network and you would like to take advantage of PXE to install RHEL on your network, you need to perform the following tasks.

# rpm -Uvh /mnt/cdrom/RedHat/RPMS/tftp-server*
3. Remove the CD from the server after you enter the following command:
4. Edit and save the /etc/xinetd.d/tftp file.
Make the following changes:
Change the -s /tftpboot entry to -v -s /home/pxeboot .
Change the disable attribute to no .
5. Restart the inetd server. Enter:
# service xinetd restart
To Install and Configure the neopxe Boot Ser ver Daemon
Complete the following steps on your DHCP server. The neopxe server is designed for use with a DHCP server that is running on the same system.
1. Install the neopxe boot server daemon onto the system that is your DHCP server. Enter:
2. Append the path /usr/local/sbin/neopxe to the rc.local file by entering the following command, making sure to use two greater-than signs:
# echo «/usr/local/sbin/neopxe» >> /etc/rc.d/rc.local
3. Copy the PXE Linux image from the /tmp/ directory. Enter:
# cp /tmp/rhel4-pxefiles/pxelinux.0 /home/pxeboot
4. Configure the PXE Linux image. Enter:
5. Edit the /usr/local/etc/neopxe.conf configuration file, which is read by neopxe at startup.
If the neopxe.conf file is not in the /usr/local/etc directory, copy it from the /tmp/ rhel4 -pxefiles/neopxe-0.2.0/ directory.
A valid configuration file must have entries for each of the following lines, including at least one service line.
n.n.n.n is the IP address of your PXE server.
boot-prompt-string is the character string displayed during a network boot that prompts the user to press the F8 key for a boot menu.
timeout is the number of seconds the prompt is displayed before the server defaults to the first service for booting.
service-number is an integer in the range of 1 to 254 that identifies the boot service.
boot-server is the IP address of the boot server for that boot service.
boot-file is the name of the boot file that is read from your /home/pxeboot directory.
label is the text string that is displayed when the boot menu is invoked by pressing the F8 key.
prompt=Press [F8] for menu.
| Note — Refer to the neopxe.conf man page for more information. |
6. Start the neopxe daemon. Enter:
To Configure the NFS Service on Your DHCP Server

| Note — If you are using a DNS server, verify that DNS entries exist for the range of addresses defined in the PXE subnet dynamic-bootp entry in the dhcpd.conf file. If you are not using a DNS server, edit the /etc/hosts file to add the range of host addresses found in the PXE subnet dynamic-bootp entry in the dhcpd.conf file. |
To Disable the F irewall
 | Caution — Security vulnerability. When you disable the firewall protection on the system that is your PXE server, the security of the data on that server cannot be ensured. If this server is networked outside of your local intranet, be sure to re-enable the firewall after downloading software to PXE clients. |
If you enabled firewall security when you installed RHEL software on the system that will be your PXE server, complete the following steps to disable the firewall so that PXE clients can download from the server.
1. Stop the ipchains service. Enter the command:
# service ipchains stop
2. Stop the iptables service. Enter the command:
# service iptables stop
3. Stop the ipchains service from starting when you restart the server. Enter the command:
# chkconfig ipchains off
4. Stop the iptables service from starting when you restart the server. Enter the command:
# chkconfig iptables off
| Note — You might encounter error messages if the ipchains service is not installed on the server. You can safely ignore these messages. |
Installing RHEL From the Network
When you have completed all the previous configuration steps, do the following.
1. Reboot the PXE/DHCP server.
Creating a PXE Install Image o n the PXE Server
This procedure describes how to create a Preboot Execution Environment (PXE) install image on the same server that is your DHCP server so that it will also act as your PXE server. The PXE server provides the operating system files to your PXE client.
Before You Begin
Before you install a RHEL image on your PXE server, you must configure your Linux network to support PXE images. See Preconfiguring Your Network to Support PXE Installation of RHEL.
Required Items
The PXE installation procedure requires the following items:
A CD/DVD drive on the DHCP Server
RHEL 4 U4 (or later) or RHEL 5 media CD set (see Obtaining Updated Media Kits)
Tools and Drivers CD (707-0095)
To Create a RHEL Image on Your PXE Install Server
| Note — For RHEL 5.x, please replace the appropriate filenames with the names of the RHEL5 files supplied in the resource CD. |
1. Insert the Tools and Drivers CD into the CD/DVD drive of the DHCP/PXE server.
2. Enter the following commands to copy the Sun support files from the CD to the /tmp directory on your DHCP/PXE server:
# mount /dev/cdrom /mnt/cdrom
# cp -a /mnt/cdrom/Linux/pxe/rhel4-pxefiles.tar.gz /tmp
# tar -zxvf rhel4-pxefiles.tar.gz
3. Set up the directory structure that will hold the RHEL software. Enter:
# mkdir -p /home/pxeboot/rhel4/
| Note — You can use a different target directory than the /home/pxeboot/rhel4/ directory shown below. The examples in this procedure use this directory. |
4. For each RHEL Distribution CD, enter the following commands to copy the contents of the CD to the appropriate PXE target subdirectory:
# mount dev/cdrom /mnt/cdrom
# cp -a /mnt/cdrom/* /home/pxeboot/rhel4/
| Note — If you are prompted whether to overwrite any existing files, enter y to overwrite the files. Eject and insert RHEL CDs only when the CD/DVD drive is unmounted. |
5. Copy the kickstart file ks.cfg to your PXE server. Enter:
# cp /tmp/rhel4-pxefile/ks.cfg /home/pxeboot/rhel4/
The kickstart configuration file contains a configuration that might not be optimal for your operating environment. Modify the file as necessary to suit your environment.
6. Copy the initial ramdisk from the PXE files uncompressed in Step 2 into the base of the PXE image. Enter:
# cp /tmp/rhel4-pxefiles/initrd.img /home/pxeboot/rhel4/
7. On your PXE server, edit and save the kickstart file: /home/pxeboot/rhel4/ks.cfg.
Edit the nfs line is as follows:
nfs —server n.n.n.n —dir /home/pxeboot/rhel4/
Where n.n.n.n is the IP address of your PXE server. Ensure that the location indicated after —dir is pointing to the top level of your image.
8. Create a default directory for the pxelinux.cfg image:
# mkdir /home/pxeboot /pxelinux.cfg/default
9. Add the following entry to the file /home/pxeboot/pxelinux.cfg/default :
| Note — Enter the text block from append through ks.cfg as one continuous string with no returns. |
append ksdevice=eth0 console=tty0 load_ramdisk=1
initrd=rhel4/initrd.img network
ks=nfs: n.n.n.n :/home/pxeboot/
Where n.n.n.n is the IP address of your PXE server.
| Note — For console-based installations, add console=ttyS0,9600 to the append line. |
10. Save the modified version of the /home/pxeboot/pxelinux.cfg/default file.
11. Insert the RHEL Distribution CD1 into the CD/DVD drive of the DHCP/PXE server.
# mount /dev/cdrom /mnt/cdrom
# cp /mnt/cdrom/images/pxeboot/vmlinuz /home/pxeboot/rhel4/
Installing RHEL F rom a PXE Server
This procedure describes how to configure your Sun Blade X6220 server module to initiate the request to download the boot image file from the PXE/DHCP server and how to install the RHEL boot image onto your Sun Blade X6220 server module.
Before You Begin
Before you configure your server to install RHEL from a PXE server, you need to have done the following:
Installed a RHEL image on that Linux PXE server. See Creating a PXE Install Image on the PXE Server.
To Install a RHEL from a PXE Server
1. Connect the PXE client to the same network as the PXE server, and power on the PXE client.
The PXE client is the target Sun Blade X6220 server module to which you are installing RHEL software.
2. When the PXE client prompts you for a network boot, press the F12 key.
The PXE client connects to the PXE server and attempts to obtain an IP address from the DHCP server.
3. When prompted, press the F8 key to begin downloading the PXE boot image.
4. At the boot: prompt, enter in the label you gave the image when you installed a RHEL image on the PXE server.
The RHEL install image downloads onto the target Sun Blade X6220 server module.
5. To configure the Linux operating system for your server, refer to the manual that is shipped with your RHEL media kit.
6. Update the SCSI drivers.
7. Update the operating system files.
To Update the RHEL SCSI Drivers
1. Insert the Tools and Drivers CD for Sun Blade X6220 and mount it onto the directory /mnt as explained in the previous section. Enter the following commands:
For RHEL 4.6 and older, 32 bit:
# rpm -ivh mptlinux-redhat4.0-3.12.27.00-2.i686.rpm
For RHEL 4.6 and older, 64 bit:
# rpm -ivh mptlinux-redhat4.0-3.12.27.00-2.x86_64.rpm
For RHEL 5.0 and 5.1, 64 bit:
# rpm -ivh mptlinux-4.00.22.00-1-rhel5.x86_64.rpm
2. Installation of the new drivers is now complete. Reboot the blade for the changes to take effect. Enter:
Since software is constantly being updated, your distribution media might not contain the most up-to-date versions of the operating system.
The following procedures assume that you have already installed the RHEL software on the Sun Blade X6220 server module. This procedure explains how to update the RHEL installation with the latest OS.
To use the RHEL 5 update program, your server must be registered with the RedHAt Network (RHN).
To Update the RHEL4 Software
This procedure assumes that your system has access to the internet.
1. Set up the up2date program on the server.
Refer to the documentation included with your RHEL media kit for details.
2. Run the up2date program.
Select the kernel packages in the available package updates section.
To Update the RHEL5 Software
Your system must have access to the internet and be registered with the RedHat Network.
1. To run the yum update program, enter:
The program checks that the machine is registered with RedHat Network. If so, yum downloads necessary updates from the RedHat Network repository.
2. Answer the questions and make your choices before the packages are downloaded and installed.
You should periodically update your system using yum .
