Kick Start Installation and Configuration

What is Kickstart?

   Installing Red Hat based systems from physical or virtual media is easy enough when there are only one or two hosts to install. Beyond this, when an administrator needs to setup several Linux systems, Kickstart can provide a relatively easy way to accomplish mass deployment and can be totally automated. It is easy to have several different Kickstart configurations ready to go, each having a different deployment configuration.

    Most large companies use this technique to deploy a Red Hat base server image that can then be customized as required. What makes Kickstart even easier is that an administrator can configure Kickstart with nothing more complex than a web server, installation media and at least one Kickstart configuration file. The only other requirement is an active DHCP server so that new clients waiting to be kick started can reach the Kickstart server, having obtained a valid DHCP address. Kickstart can also use other installation mediums, such as NFS and even local media if desired.

Just we can say un-attended installation process, this can be configured using

1.    NFS

2.    FTP

3.    HTTP

Prerequisites: -

·         Required installation media

·         Configure FTP site to share packages

·         Configure DHCP server

To copy all the packages from installation media mount the DVD to mount point

# mount /dev/dvd /media

Install FTP packages
# rpm -ivh vsftpd-2.0.5-10.el5.i386.rpm

Copy the data from /media to /var/ftp/pub/

# cp –Rv /media/* /var/ftp/pub

Start the ftp service

# service vsftpd restart; chkconfig vsftpd on

Stop firewall and SELinux security for now.

# service iptables stop

# vi /etc/selinux/config

In 6th line change from enforcing to disabled.


Save & exit

Install and start the DHCP service

# rpm -ivh dhcp-3.0.5-3.el5.i386.rpm

After installing the dhcp package DHCP sample configuration file will be available in /usr/share/doc/dhcp*/dhcpd.conf

Copy above sample file to /etc/dhcpd.conf then modify as per your requirement.

# cat dhcpd.conf.sample > /etc/dhcpd.conf

Edit the main config file now

# vi /etc/dhcpd.conf

# cat /etc/dhcpd.conf

#--------------------------Configuration File Starting----------------#
ddns-update-style interim;

ignore client-updates;

subnet netmask {

# --- default gateway

        option routers        ;

        option subnet-mask    ;

        option nis-domain               "";

        option domain-name              "";

        option domain-name-servers;

        option time-offset              -18000; # Eastern Standard Time

#       option ntp-servers    ;

#       option netbios-name-servers;

# --- Selects point-to-point node (default is hybrid). Don't change this unless

# -- you understand Netbios very well

#       option netbios-node-type 2;

        range dynamic-bootp;

        default-lease-time 21600;

        max-lease-time 43200;

        # we want the nameserver to appear at a fixed address

        host ns {

                next-server localhost.localdomain;

                hardware ethernet 00:0C:29:07:8D:6B;



# --------------------- Config file END -------------#


# service dhcpd restart

Copy the below sample configuration file

In this case i have created a file in /var/ftp/pub/rhel5.cfg

#sample KickStart File Start


url --url=

key --skip

lang en_US.UTF-8

keyboard us

network --onboot yes --device eth0 --bootproto dhcp


rootpw redhat

firewall --disabled

authconfig --enableshadow --enablemd5

selinux --disabled

timezone America/New_York

bootloader --location=mbr --append="rhgb quiet"

clearpart --all

part / --fstype ext3 --size=4000

part /boot --fstype ext3 --size=100

part swap --size=2000

%packages --nobase



Then boot the station1 with installation media (RHEL5/6)

When it will boot with CD/DVD enter

Boot: linux ks=

Installation will continue and it will complete automatically.
