Open Suse pxe-installation

 

Install syslinux rpm file and it will create a file pxelinux.0 in /usr/share/syslinux/pxelinux.0

 

create bootimage file in tftp using yast as /srv/tftboot

 

 

his configuration file refers to 2 important files: linux and initrd. They have to be downloaded from the network SuSE install repository (or a mirror). or from DVD.
 

# cd /srv/tftpboot
 

copy linux and intrd files from dvd in /boot/i386/loader/ to /srv/tftboot/
 

( or )
 

download linux and initrd file in /srv/tftboot/
 

# wget http://download.opensuse.org/factory/repo/oss/boot/i386/loader/linux
 

# wget http://download.opensuse.org/factory/repo/oss/boot/i386/loader/initrd
 

# wget -O initrd64 http://download.opensuse.org/factory/repo/oss/boot/x86_64/loader/initrd
 

# wget -O linux64 http://download.opensuse.org/factory/repo/oss/boot/x86_64/loader/linux
 

At that point, you should have everything to build your PXE boot environment. Create the initial directory structure under the TFTP root directory as shown below:
 

# mkdir -p /srv/tftpboot/pxelinux.cfg
 

copy isolinux.cfg file from dvd in boot/i386/loader folder into /srv/tftboot/default (rename isolinux.cfg filename as default)
 

Copy PXE bootstrap file into tftpboot directory.
 

# cp /usr/share/syslinux/pxelinux.0 /srv/tftpboot
 

create dhcpd.conf file as below
 

# dhcpd.conf
 

#
 

# Sample <span class="IL_AD" id="IL_AD3">configuration file</span> for ISC dhcpd
 

## option definitions common to all supported networks…
 

#
 

# All of this happens behind the firewall, and the whole domain
 

# is made-up anwyay, so this is mostly fluff.
 

#
 

#option domain-name "vavai.net";
 

 

# We don't have Nameservers… so let's just forget this item
 

#option domain-name-servers ns1.networkboot.org, ns2.networkboot.org;
 

 

default-lease-time 600;
 

max-lease-time 7200;
 

# if you do not use dynamical DNS updates:
 

#
 

# this statement is needed by dhcpd-3 needs at least this statement.
 

# you have to delete it for dhcpd-2, because it does not know it.
 

#
 

# if you want to use dynamical DNS updates, you should first read
 

# read /usr/share/doc/packages/dhcp-server/DDNS-howto.txt
 

ddns-update-style none; ddns-updates off;
 

# If this <span class="IL_AD" id="IL_AD5">DHCP server</span> is the official DHCP server for the local
 

# network, the authoritative directive should be uncommented.
 

#authoritative;
 

 

# Use this to send dhcp log messages to a different log file (you also
 

# have to hack syslog.conf to complete the redirection).
 

log-facility local7;
 

 

# We only want to respond to PXE DHCP requests
 

 

allow booting;
 

 

# define rules to identify DHCP Requests from PXE and Etherboot clients.
 

 

class "pxe" {
 

match if substring (option vendor-class-identifier, 0, 9) = "PXEClient";
 

}

class "etherboot" {

match if substring (option vendor-class-identifier, 0, 9) = "Etherboot";

}

 

# This is our subnet for PXE boot/installation.
 

 

subnet 10.199.50.0 netmask 255.255.255.0 {
 

option broadcast-address 10.199.50.255;
 

pool {
 

range 10.199.50.101 10.199.50.150; # only need a few addresses
 

default-lease-time 180; # no long lease time required for booting
 

max-lease-time 360; # booted system does its own dhcp request
 

server-name "10.199.50.8"; # This happens to be the IP of this server too
 

next-server 10.199.50.8; # Address of the TFTP server
 

filename "pxelinux.0";
 

allow members of "pxe"; # only respond to PXE requests
 

allow members of "etherboot"; # allow etherboot, too
 

}

}

 

Edit /etc/sysconfig/dhcpd and activate the ethernet used for listen DHCP request. If you confused which ethernet will be used, try with ANY as suggested on the configuration. I’m using eth0 so part of my configuration look like this :
 

1.# Examples: DHCPD_INTERFACE="eth0"
 

2.# DHCPD_INTERFACE="eth0 eth1 eth2 tr0 wlan0"
 

3.# DHCPD_INTERFACE="internal0 internal1"
 

4.# DHCPD_INTERFACE="ANY"
 

5.#
 

6.DHCPD_INTERFACE="eth0"
 

 

Restart the DHCP Service
 

USING PXE BOOT FOR INSTALLATION

 

1. Prepare a PC with attached Network card. This computer will be used as client for PXE Boot Installation
 

2. Change BIOS Setting, activating Boot from LAN and switch the Boot Default Priority to boot from LAN
 

3. Restart the computer. It will boot from LAN and display the installation option.
 

 

DISPLAYING PXE BOOT FOR INSTALLATION

 

 

modify default file as like this if you have a problem

default harddisk

# hard disk
 

label harddisk
 

localboot 0x80

 

# install
 

label linux
 

kernel linux
 

append initrd=initrd splash=silent showopts
