pxeboot man page.
4. TFTPD
4.1. Starting the tftp Server
On the DHCP server, verify that the tftp-server package is installed with the command rpm
-q tftp-server. If it is not installed, install it via Red Hat Network or the Red Hat Enterprise
Linux CD-ROMs.
Note
For more information on installing RPM packages, refer to the Package
Management Section of the Red Hat Enterprise Linux Deployment Guide.
tftp is an xinetd-based service; start it with the following commands:
/sbin/chkconfig --level 345 xinetd on /sbin/chkconfig --level 345 tftp on
These commands configure the tftp and xinetd services to immediately turn on and also
configure them to start at boot time in runlevels 3, 4, and 5.
5. Configuring the DHCP Server
If a DHCP server does not already exist on the network, configure one. Refer to the Red Hat
Enterprise Linux Deployment Guide for details. Make sure the configuration file contains the
following so that PXE booting is enabled for systems which support it:
allow booting; allow bootp; class "pxeclients" { match if substring(option
vendor-class-identifier, 0, 9) = "PXEClient"; next-server ;
filename "linux-install/pxelinux.0"; }
where the next-server should be replaced with the IP address of the tftp server.
6. Adding a Custom Boot Message
Optionally, modify /tftpboot/linux-install/msgs/boot.msg to use a custom boot message.
7. Performing the PXE Installation
For instructions on how to configure the network interface card with PXE support to boot from
the network, consult the documentation for the NIC. It varies slightly per card.
