22. Continue to Updating the Operating System and Drivers for information on updating the Red Hat Enterprise Linux 3 Software.
The tasks for installing Red Hat Enterprise Linux 3 software from a networked PXE server consist of the following procedures.
1. Configure your network to support PXE installation. See Preconfiguring Your Network to Support PXE Installation.
2. Create a PXE install image on a system that will be the PXE server, from which the software is downloaded to other systems (PXE clients). See Creating a PXE Install Image on the PXE Server.
3. Install the Red Hat software to the PXE clients from the PXE server. See Installing the Software from a PXE Server.
4. Update the Red Hat software. See Updating the Operating System and Drivers.
The PXE installation procedure requires the following items.
This procedure describes how to create a 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.
|
Note - Before you start this procedure, verify that your network has been configured as described in Preconfiguring Your Network to Support PXE Installation. |
1. Insert Red Hat Enterprise Linux 3 CD 1 into your DHCP/PXE server and copy its contents to your PXE server, by typing the commands listed below:
You can use a different target directory than the /home/pxeboot/SunFire_rhel3/ directory shown below. The examples in this procedure use this directory.
# mkdir -p /home/pxeboot/SunFire_rhel3/
# cp -a /mnt/cdrom/RedHat /home/pxeboot/SunFire_rhel3/
2. Copy the initial ramdisk and kernel from CD 1 into the base of the PXE image with the following commands:
# cp /mnt/cdrom/images/pxeboot/initrd.img \
/home/pxeboot/SunFire_rhel3/
# cp /mnt/cdrom/images/pxeboot/vmlinuz \
/home/pxeboot/SunFire_rhel3/
3. Unmount CD 1 with the following command and remove it from the server:
4. Insert Red Hat Enterprise Linux 3 CD 2 into your server and copy its contents to your PXE server, by typing the following commands:
# cp -a /mnt/cdrom/RedHat /home/pxeboot/SunFire_rhel3/
If you are prompted whether to overwrite any existing files, type y to overwrite the files.
5. Unmount CD 2 with the following command and remove it from the server:
6. Insert Red Hat Enterprise Linux 3 CD 3 into your server and copy its contents to your PXE server, by typing the following commands:
# cp -a /mnt/cdrom/RedHat /home/pxeboot/SunFire_rhel3/
If you are prompted whether to overwrite any existing files, type y to overwrite the files.
7. Unmount CD 3 with the following command and remove it from the server: :
8. Insert Red Hat Enterprise Linux 3 CD 4 into your server and copy its contents to your PXE server, by typing the following commands:
# cp -a /mnt/cdrom/RedHat /home/pxeboot/SunFire_rhel3/
If you are prompted whether to overwrite any existing files, type y to overwrite the files.
9. Unmount CD 4 with the following command and remove it from the server:
10. Copy the kickstart file ks.cfg to your PXE server by typing the following command:
# cp /tmp/rhel3_64-pxefiles/ks.cfg /home/pxeboot/SunFire_rhel3/
11. Copy the SCSI and network drivers from the temporary directory to the directory shown below:
# cp /tmp/rhel3_64-pxefiles/bcm* /home/pxeboot/SunFire_rhel3/
# cp /tmp/rhel3_64-pxefiles/lsi* /home/pxeboot/SunFire_rhel3/
12. On your PXE server, edit and save the kickstart file /home/pxeboot/SunFire_rhel3/ks.cfg so that the nfs line is as follows:
nfs --server n.n.n.n --dir /home/pxeboot/SunFire_rhel3/
Where n.n.n.n is the IP address of your PXE server. Double check that the location indicated after --dir is pointing to the top level of your image.
13. On your PXE server, modify and save the file /home/pxeboot/pxelinux.cfg/default to add the following entry to it:
Note that you should type the text block from append ksdevice through ks.cfg as one continuous string with no returns.
default SunFire_rhel3
label SunFire_rhel3
kernel SunFire_rhel3/vmlinuz
append ksdevice=eth0 console=tty0
load_ramdisk=1 initrd=SunFire_rhel3/initrd.img network
ks=nfs:n.n.n.n:/home/pxeboot/SunFire_rhel3/ks.cfg
Where n.n.n.n is the IP address of your PXE server.
|
Note - For console-based installations, add console=ttyS0,19200 to the append line. |
This procedure describes how to initiate the request from the target Sun Fire V20z or Sun Fire V40z server to download the boot image file from the PXE/DHCP server and to install the Red Hat Enterprise Linux 3 software onto the target server.
|
Note - This procedure assumes that you have already preconfigured your network and PXE server install image as described in Preconfiguring Your Network to Support PXE Installation and Creating a PXE Install Image on the 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 Fire V20z or Sun Fire V40z server to which you are installing Red Hat Enterprise Linux 3 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. Press the F8 key to begin the downloading of the PXE boot image.
4. If you are prompted at the boot: prompt, type in the label you gave the image in Step 13 of Creating a PXE Install Image on the PXE Server.
The Red Hat Enterprise Linux 3 install image downloads onto the target Sun Fire V20z or Sun Fire V40z server.
5. To configure the Linux operating system for your server, refer to the manual that is shipped with your Red Hat Enterprise Linux 3 media kit.
6. Proceed to Updating the Operating System and Drivers.
The CD media may not contain the most up-to-date versions of the software. Since the media has been released, there have been many updates to the software.
See the following sections for instructions on updating the Red Hat Enterprise Linux 3 software.
The CD media does not contain the most up-to-date versions of the software. Since the media has been released, there have been many updates to the Red Hat Enterprise Linux software. To keep your system protected against security threats and increase stability, you should run the up2date program when the system is fully installed.
Refer to the Red Hat manual included with your Red Hat Enterprise Linux 3 media kit for information about setting up the up2date program. When running up2date, select the kernel packages on the available package updates section. After up2date has completed, reboot the server.
The kernel that is installed on the system might not contain the optimal drivers that Sun Microsystems recommends. Updating the drivers ensures proper system performance.
The instructions below describe how to copy the latest drivers from the Sun Fire V20z and Sun Fire V40z Servers Documentation and Support Files CD. You can also download the driver RPMs from the product pages for the Sun Fire V20z and Sun Fire V40z servers. The following URL is valid for both servers:
http://www.sun.com/servers/entry/v20z/downloads.html
1. Determine which kernel is currently installed on the system by running the following command:
The following is an example of the output you might get:
kernel-2.4.21-4.EL.x86_64
kernel-smp-2.4.21-4.EL.x86_64
kernel-source-2.4.21-4.EL.x86_64
In this example, you are running the 2.4.21-4.EL.x86_64 kernel.
2. Insert the Documentation and Support Files CD into the server.
3. Mount the CD and locate the Ethernet and SCSI drivers by typing the following commands:
# mount /dev/cdrom /mnt/cdrom
# cd /mnt/cdrom/support/drivers/rhel3/64/
|
Note - If you are using the 32-bit version of Red Hat Enterprise Linux, the directory to change to is:
|
4. Determine which driver RPMs correspond to the kernel version, as determined in Step 1.
The filenames of the RPMs contain the kernel version and type. Using the example kernel versions shown in Step 1, the Ethernet (bcm5700) and SCSI (lsi) drivers would be:
bcm5700-7.1.22_2.4.21_4.EL-rhel3_1.x86_64.rpm
bcm5700-smp-7.1.22_2.4.21_4.EL-rhel3_1.x86_64.rpm
lsi-2.05.11_2.4.21_4.EL-rhel3_1.x86_64.rpm
lsi-smp-2.05.11_2.4.21_4.EL-rhel3_1.x86_64.rpm
5. Run the following command to install the RPM files:
# rpm -Uvh /mnt/cdrom/support/drivers/rhel3/64/bcm5700-drivers.rpm
# rpm -Uvh /mnt/cdrom/support/drivers/rhel3/64/lsi-drivers.rpm
Where bcm5700-drivers and lsi-drivers refer to the appropriate Ethernet and SCSI driver RPM files, as determined in Step 4.
6. Locate the NPS RPM on the Documentation and Support Files CD that corresponds to your operating system version and architecture.
The NPS RPM files are located in OS-specific directories within this top level path on the CD: /support/sysmgmt/
7. Install the NPS RPM by typing the following command:
# rpm -Uvh /mnt/cdrom/support/sysmgmt/redhat/rhel3/nps-V2.rpm
Where nps-V2 represents the version and architecture of the NPS RPM file.
Alternatively, the NPS RPM can be compiled and installed from source by typing the following commands:
# tar -xvf /mnt/cdrom/support/sysmgmt/src/nps-V2*.tar.gz
# rpm -ivh `find ./RPMS | grep nps`
|
Note - Some Linux variants might require the rpmbuild command instead of the rpm command. Check with the documentation for your version of Linux. |
8. After successful installation, reboot the system by running the following command:
