How to Create a PXE Installation Image for Oracle
Enterprise Linux
When you create a Oracle Linux Preboot Execution Environment (PXE) installation image on
the same server that is your DHCP server, it will also act as your PXE server. The PXE server
provides the operating system files to your PXE client.
Before you install a Oracle Enterprise Linux image on your PXE server, you must configure
your Linux network to support PXE images. See
“Overview of PXE Servers” on page 42
The PXE installation procedure requires the following items:
■
A CD/DVD drive on the DHCP server.
■
Oracle Enterprise Linux media set. This can be a set of CDs or a DVD.
■
A copy of the Oracle Enterprise Linux files from the Tools and Drivers CD.
Set up the directory structure that will hold the Oracle Enterprise Linux software.
#
mkdir -p /home/pxeboot/oel5/
For each Oracle Enterprise Linux Distribution CD, type the following commands to copy the
contents of the each distribution CD to the appropriate PXE target subdirectory.
Note –
Eject and insert CDs only when the CD/DVD drive is unmounted.
#
mount dev/cdrom /mnt/cdrom
#
cp -r /mnt/cdrom/* /home/pxeboot/oel5/
#
umount /mnt/cdrom
If you are installing from a DVD, you have to do this only once. When the copy is done, proceed
to the next step.
Copy the
vmlinuz
and
initrd.img
files to the appropriate PXE target subdirectory
(
/home/pxeboot/oel5/
).
#
cp /home/pxeboot/oel5/images/pxeboot/vmlinuz /home/pxeboot/oel5/
#
cp /home/pxeboot/oel5/images/pxeboot/initrd.img /home/pxeboot/oel5/
Copy the kickstart file
ks.cfg
to your PXE server. Type:
#
cp /tmp/oel5u4-pxefile/ks.cfg /home/pxeboot/oel5/
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.
For example, to make the OEL 5.4 installation process fully automatic, add the following line to
the end of the kickstart configuration file:
key --skip
