Installation guide

Note
For more information on installing RPM packages, refer to the Package Manage-
ment 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 con-
figure 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 fol-
lowing 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 <server-ip>; filename "linux-in-
stall/pxelinux.0"; }
where the next-server <server-ip> 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.
After the system boots the installation program, refer to the Red Hat Enterprise Linux Installation
Guide.
