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
dhcp-option=3,172.17.199.199
# DNS
dhcp-option=6,172.17.199.199, 8.8.8.8
# Broadcast Address
dhcp-option=28,172.17.255.255
# NTP Server
dhcp-option=42,0.0.0.0
# PXE
dhcp-boot=pxelinux.0
pxe-service=x86PC, "Linuxtopic.com", pxelinux
# Enable TFTP
enable-tftp
tftp-root=/var/lib/tftpboot
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
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

APPEND initrd=data/centos7_64Bit/images/pxeboot/initrd.img method=http://172.17.199.199/pxeboot/centos7_64Bit devfs=nomount
Optional Step 7:
Boot From Clonezilla ISO
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
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
Hi, this post was so useful.
ReplyDeleteI tried to simulate this structure, but I had a problem. When I try to install a Debian 10, after the client starts the installation, the client prompt aks for a installation media. I tried all initrd and kernel images, but it doesn't work. What could be the problem? Am I missing some argument?
