sudo apt install atftpd syslinux -y

sudo systemctl enable atftpd sudo systemctl restart atftpd create configuration directories

mkdir -pv /srv/tftp/{,krls,imgs,iso,pxelinux.cfg}

copy memdisk kernel

cp -v /usr/lib/syslinux/memdisk /srv/tftp/krls

copy necessary files

cp -v /usr/lib/syslinux/modules/bios/{ldlinux.c32,libcom32.c32,libutil.c32,chain.c32,vesamenu.c32} /srv/tftp

get pxelinux.0 file

wget -O /srv/tftp/pxelinux.0 http://archive.ubuntu.com/ubuntu/dists/xenial/main/installer-amd64/current/images/netboot/pxelinux.0

copy pxelinux.0 to tftp root
cp ~/pxelinux.0 /srv/tftp
start manually
sudo atftpd --daemon /srv/tftp
setup tftp as service

sed -i s,USE_INETD=true,USE_INETD=false,g /etc/default/atftpd

now start service

/etc/init.d/atftpd start

iPXE Setup

apt install git make gcc liblzma-dev mkisofs isolinux

compile it

git clone git://git.ipxe.org/ipxe.git

create ipxe script

nano ~/menu.ipxe

and paste the following in it

#!ipxe
dhcp 
params
param mac ${net0/mac}
chain http://${next-server}/ipxe/index.php##params

go to ipxe source directory

cd ipxe/src

make some changes to setting to include needed iPXE commands


sed -i s,'//#define IMAGE_MULTIBOOT','#define IMAGE_MULTIBOOT',g config/general.h
sed -i s,'//#define IMAGE_PXE','#define IMAGE_PXE',g config/general.h
sed -i s,'//#define IMAGE_SCRIPT','#define IMAGE_SCRIPT',g config/general.h
sed -i s,'//#define IMAGE_BZIMAGE','#define IMAGE_BZIMAGE',g config/general.h

uncomment IMAGE_MULTIBOOT, IMAGE_PXE, IMAGE_SCRIPT, IMAGE_BZIMAGE, IMAGE_PNG. In my setup they are on line 106-109 and 114, lines will vary so check before hand
sed -i '106,109 s,//,,' config/general.h sed -i '114 s,//,,' config/general.h
uncomment useful commands to be added in iPXE from config/general.h file

sed -i s,'//#define IMAGE_MULTIBOOT','#define IMAGE_MULTIBOOT',g config/general.h
sed -i s,'//#define IMAGE_PXE','#define IMAGE_PXE',g config/general.h
sed -i s,'//#define IMAGE_SCRIPT','#define IMAGE_SCRIPT',g config/general.h
sed -i s,'//#define IMAGE_BZIMAGE','#define IMAGE_BZIMAGE',g config/general.h
sed -i s,'//#define NSLOOKUP_CMD','#define NSLOOKUP_CMD',g config/general.h
sed -i s,'//#define TIME_CMD','#define TIME_CMD',g config/general.h
sed -i s,'//#define VLAN_CMD','#define VLAN_CMD',g config/general.h
sed -i s,'//#define PXE_CMD','#define PXE_CMD',g config/general.h
sed -i s,'//#define REBOOT_CMD','#define REBOOT_CMD',g config/general.h
sed -i s,'//#define POWEROFF_CMD','#define POWEROFF_CMD',g config/general.h
sed -i s,'//#define PCI_CMD','#define PCI_CMD',g config/general.h
sed -i s,'//#define PARAM_CMD','#define PARAM_CMD',g config/general.h
sed -i s,'//#define PING_CMD','#define PING_CMD',g config/general.h
sed -i s,'//#define CONSOLE_CMD','#define CONSOLE_CMD',g config/general.h
sed -i s,'//#define IPSTAT_CMD','#define IPSTAT_CMD',g config/general.h
sed -i s,'//#define NTP_CMD','#define NTP_CMD',g config/general.h

uncomment useful commands to be added in iPXE from config/settings.h file, in my setup they are on line 13-16

sed -i '12,16 s,//,,' config/settings.h

now compile ipxe.iso file with embedded script menu.ipxe
make bin/ipxe.iso EMBED=~/menu.ipxe
compile ipxe.lkrn

make bin/ipxe.lkrn

copy ipxe.lkrn to tftp

cp ~/ipxe/src/bin/ipxe.lkrn /srv/tftp/krls/

setup tftp/pxe to load ipxe

That is it, your PXE server is ready with iPXE support. Now install Apache and php

apt install apache2 libapache2-mod-php php php-doc php-cli php-cgi php-mysql php-ldap mysql-client

now create separate directory for ipxe

mkdir -pv /var/www/html/ipxe

create ipxe menu file

cat << eot > /var/www/html/ipxe/index.php

eot

create directories for boot kernels, boot images, and boot iso

mkdir -pv /var/www/html/ipxe/{,krls,imgs,iso}
