step by step configure pxeboot server in Ubuntu | PXE network boot server

step by step configure pxeboot server in Ubuntu | PXE network boot server

PXE stand for Preboot eXecution Environment it works on Client-Server architecture and allows unattended or automated OS installation over the Network

Point to be noted :

This PXE Boot server configuration in Ubuntu 16.4,  
PXE network boot server with Configure dnsmasq with DHCP and dnsmasq without dhcp,
pxe boot server we add centos 7 boot entry in default pxelinux.cfg directory via NFS and http, 
We configure pxe boot with clonezilla iso and zip
CentOS iso pxeboot entry, Installing CentOS, Debian using network booting


Server IP = 172.17.199.199
Host name = pxeboot.linuxtopic.com
OS = Ubuntu 16

Video Tutorial in English :



Step 1:

Network Configure

vi  /etc/network/interfaces

auto eth0
iface eth0 inet static
       address 172.17.199.199
       netmask 255.255.0.0
    gateway 172.17.0.1

Note : Reboot DVC for network change

Step 2:

Install required packages

apt-get install pxelinux syslinux dnsmasq

Step 3:

Configure dnsmasq as existing dhcp on network

cp /etc/dnsmasq.conf /etc/dnsmasq.conf-bk

Option 1 :  Configure dnsmasq as existing dhcp on network

vi /etc/dnsmasq.conf

# DNS Options
port=0
interface=eth0,lo


# DHCP Options
dhcp-range=172.17.0.1,proxy
dhcp-option=vendor:PXEClient,6,2b
dhcp-no-override


# PXE
dhcp-boot=pxelinux.0


#pxe-prompt="Press F8 for menu.", 10
pxe-service=X86PC, "www.linuxtopic.com", pxelinux


# TFTP Options
enable-tftp
tftp-root=/var/lib/tftpboot

Option 2 :  Configure dnsmasq with dhcp server

# DNS Options
port=0
interface=eth0,lo


# DHCP range-leases
dhcp-range= eth0,172.17.199.200,172.17.199.250,255.255.0.0,1h
# Gateway

Explain :


port=0   -  disable dns
interface=eth0,lo   - Interfaces that the server should listen and provide services


dhcp-rang=172.17.20.100,proxy   -  existing dhcp server ip  
OR
dhcp-range= eth0,172.17.199.200,172.17.199.250,255.255.0.0,1h  - Dhcp IP Range
dhcp-option=3,172.17.199.199  - define gateway
dhcp-option=6,172.17.199.199, 8.8.8.8  - Define DNS
dhcp-option=28,172.17.255.255  - Broadcast Address
dhcp-option=42,0.0.0.0 - NTP Server


dhcp-option=vendor:PXEClient,6,2b    - download the boot file immediately by disable multicast and broadcast discovery.
dhcp-boot=pxelinux.0    -
pxe-service=X86PC, "www.linuxtopic.com", pxelinux    -  Use x86PC for 32-bit/64-bit architectures and enter a menu description prompt under string quotes. Other values types can be: Intel_Lean_Client, IA32_EFI, _EFI, Alpha, Arc_x86, BC_EFI, Xscale_EFI and X86-64_EFI, PC98, IA64
enable-tftp    -  Enables the build-in TFTP server.
tftp-root=/var/lib/tftpboot   -  the location for all netbooting files.


Step 4:

Create tftpboot directory and copy required file

mkdir /var/lib/tftpbootmkdir /var/lib/tftpboot/pxelinux.cfg

cp /usr/lib/PXELINUX/pxelinux.0 /var/lib/tftpboot/

cp /usr/lib/syslinux/modules/bios/menu.c32 /var/lib/tftpboot/

cp /usr/lib/syslinux/modules/bios/ldlinux.c32 /var/lib/tftpboot/

cp /usr/lib/syslinux/modules/bios/libmenu.c32 /var/lib/tftpboot/

cp /usr/lib/syslinux/modules/bios/libutil.c32 /var/lib/tftpboot/

cp /usr/lib/syslinux/modules/bios/libcom32.c32 /var/lib/tftpboot/

cp /usr/lib/syslinux/modules/bios/vesamenu.c32 /var/lib/tftpboot/


ls -l /var/lib/tftpboot/


Step 4:

Create default  file and add menu entry

vi /var/lib/tftpboot/pxelinux.cfg/default

default vesamenu.c32
prompt 0
timeout 50


# Local Hard Disk pxelinux.cfg default entry
LABEL 1
   MENU LABEL ^1) Boot local hard drive
   MENU AUTOBOOT
   MENU DEFAULT
   LOCALBOOT 0

configure pxe boot server, clonezilla, pxeboot server, network boot, network booting, pxe, boot from network, boot on network, network boot linux, network boot server, network boot windows 10, network boot ubuntu, network boot windows 7, network boot windows 7 diskless, how does pxe boot work, pxe boot server windows

Step 5:  

Download Clonezilla zip File from official website and extract

https://clonezilla.org/downloads/download.php?branch=stable


Create Directory and Copy clonezilla zip

mkdir /var/lib/tftpboot/clonezilla
cd  /var/lib/tftpboot/clonezilla
unzip clonezilla-live-2.5.5-38-amd64.zip

Step 6:

Create PXE Boot Entry for Image

vi /tftpboot/pxelinux.cfg/default

default vesamenu.c32
prompt 0
timeout 50


# Local Hard Disk pxelinux.cfg default entry
LABEL 1
MENU LABEL ^1) Boot local hard drive
MENU AUTOBOOT
MENU DEFAULT
LOCALBOOT 0


# Clonezilla pxelinux.cfg default entry
LABEL 2
   MENU LABEL ^2) Clonezilla Live
   KERNEL clonezilla/live/vmlinuz
   APPEND ramdisk_size=32768 initrd=clonezilla/live/initrd.img boot=live union=overlay username=user config components noswap edd=on nomodeset noeject locales=en_US.UTF-8 keyboard-layouts=NONE net.ifnames=0 ocs_live_extra_param="" ocs_live_keymap="NONE" ocs_live_batch="yes" ocs_lang="en_US.UTF-8" vga=788 ip=frommedia nosplash  fetch=tftp://172.17.199.199/clonezilla/live/filesystem.squashfs
# CentOS 7 pxelinux.cfg default entry
LABEL 3
   MENU LABEL ^3) Install CentOS 7 - NFS
   kernel data/centos7_64Bit/images/pxeboot/vmlinuz
   append initrd=data/centos7_64Bit/images/pxeboot/initrd.img inst.stage2=nfs:172.17.199.199:/var/lib/tftpboot/data/centos7_64Bit quiet


# CentOS 7 pxelinux.cfg default entry
LABEL 4
   MENU LABEL ^4) Install CentOS 7 - HTTP
   KERNEL data/centos7_64Bit/images/pxeboot/vmlinuz
   APPEND initrd=data/centos7_64Bit/images/pxeboot/initrd.img method=http://172.17.199.199/pxeboot/centos7_64Bit devfs=nomount

configure pxe boot server, clonezilla, pxeboot server, network boot, network booting, pxe, boot from network, boot on network, network boot linux, network boot server, network boot windows 10, network boot ubuntu, network boot windows 7, network boot windows 7 diskless, how does pxe boot work, pxe boot server windows

Optional Step 7:

Boot From Clonezilla ISO

Download clonezilla iso file   from https://clonezilla.org/downloads.php

cd /var/lib/tftpboot/
wget https://gensho.ftp.acc.umu.se/mirror/osdn.net/clonezilla/69273/clonezilla-live-2.5.5-38-amd64.iso -O clonezilla2.5.iso


Add Following Entry in default 
vi /tftpboot/pxelinux.cfg/default
# Clonezilla ISO pxelinux.cfg default entry

LABEL 5
MENU LABEL ^5) Clonezilla Live from ISO
root (hd0,0)
kernel memdisk
append iso initrd=clonezilla-live-2.5.0-5-amd64.iso raw

configure pxe boot server, clonezilla, pxeboot server, network boot, network booting, pxe, boot from network, boot on network, network boot linux, network boot server, network boot windows 10, network boot ubuntu, network boot windows 7, network boot windows 7 diskless, how does pxe boot work, pxe boot server windows


Step 8: 

Restart dnsmasq service and flush iptables
systemctl restart dnsmasq

Iptables -F

Your Server is Ready Now you can Boot client from LAN by select first boot device “Network” in BIOS Setting
