PXE Server in RHEL 6 ?

How to configure PXE Server in RHEL 6 ?

Server IP settings.

IP 192.168.0.70
SUBNET 255.255.255.0
nmcontrolled no
onboot yes
DNS1=192.168.0.1

Yum install system-config-kickstart
# Install the kickstart package.

system-config-kickstart
# run the kickstart utility.

In the second last option you can remove text mode installation option and opt For a graphical one. 

Select the http installation method 

Use the defaults. 

In the disk label option choose the first option (Initialize the disk label).
The partitions that I have created are like this.

Mount Point            type         size
/boot         ext4         500
 swap         swap         2048
  /                     ext4         18000

Make sure that SELinux option is disabled and Security level is set to Disable firewall.

Save the ks.cfg file to the filesystem.

Yum install –y syslinux xinetd tftp-server dhcp httpd
# Install all the required packages through yum

mkdir /var/lib/tftpboot/pxelinux.cfg

# Open the xinetd settings to enable tftp server.
# at line 14 set the parameter to no from yes.
Disable=no 

service xinetd restart
# Restart the service to apply the settings made.

chkconfig xinetd on
# set the service to start with each subsequent system reboots.

The pxe server is ready.

Plug a computer into the network and boot it through LAN using pxe.

The client pc should  have a display as below.
