Configuring a PXE boot server
Install required packages:
# yum install bind dhcp system-config-netboot tftp-server
Setup dhcpd:
# vi /etc/dhcpd.conf
ddns-update-style interim;
ignore client-updates;
subnet 10.10.10.0 netmask 255.255.255.0 {
option routers 10.10.10.1;
option subnet-mask 255.255.255.0;
option domain-name-servers 10.10.10.1;
option time-offset 7200;
range dynamic-bootp 10.10.10.10 10.10.10.15;
default-lease-time 21600;
max-lease-time 43200;
next-server 10.10.10.1;
option subnet-mask 255.255.255.0;
option broadcast-address 10.10.10.255;
filename “linux-install/pxelinux.0”;
}
Copy the vmlinuz, initrd.img to /tftpboot/linux-install directory.
Create a default:
# cat /tftpboot/linux-install/pxelinux.cfg/default
timeout 100
default el5u1
prompt 1
display boot.msg
label el5u1
kernel vmlinuz
append initrd=initrd.img
#
Set the boot message:
# cat /tftpboot/linux-install/pxelinux.cfg/boot.msg
Press “Enter” to start or auto 100 seconds …
#
Set disable=no in /etc/xinetd.d/tftp (enable tftp)
Setup the services:
# service xinetd restart
# service dhcpd restart
# touch /etc/named.conf
# service named restart
# service iptables stop (or allow tftp connection in the iptables config)
