Determine whether the DHCP server package is already installed on the server.
#
rpm -qa | grep dhcp-
If the DHCP server package is not listed, install the DHCP server.
a. Mount the CD/DVD drive. Type the command:
#
mount /dev/cdrom /mnt/cdrom
b. Install the DHCP server.
■
For RHEL 4.8, insert the DVD or CD5 and type:
#
rpm -Uvh /mnt/cdrom/RedHat/RPMS/dhcp-*.rpm
■
For RHEL 5.3, insert the DVD or CD4 and type:
#
rpm -Uvh /mnt/cdrom/Server/dchp*
■
For SLES10 SP2, insert DVD1 or CD2 and type:
#
rpm -Uvh /mnt/cdrom/suse/x86_64/dhcp*
■
For SLES11, insert DVD1 and type:
#
rpm -Uvh /mnt/cdrom/suse/x86_64/dhcp*
c. Unmount the CD/DVD drive. Type:
#
umount /dev/cdrom /mnt/cdrom
d. Remove the CD or DVD from the CD/DVD drive.
Set up your DHCP configuration file (for example,
/etc/dhcpd.conf
) so that only PXEClient
requests receive PXEClient responses.
Note –
If the server does not already have a
dhcpd.conf
file in its
/etc
directory, you can copy
the
dhcpd.conf
file from the sample DHCP configuration file in the
/tmp/rhel4u3-pxefiles
directory.
Add the following entry to the DHCP configuration file (refer to the
dhcpd.conf
man page for
more information):
class
"
PXE
"
{match if substring(option vendor-class-identifier, 0, 9) =
"
PXEClient
"
;
option vendor-class-identifier
"
PXEClient
"
; vendor-option-space PXE; next-server
n.n.n.n
}
where
n.n.n.n
is the PXE server’s IP address.
In the DHCP configuration file, edit the
server-identifier
entry:
server-identifier
n.n.n.n
