Installation
First, you should Install and configure
DHCP server on your PXE server. To install and configure DHCP server,
refer the following link:
Now, install the following packages for setting up PXE environment:
# yum install httpd xinetd syslinux tftp-server -y
Configure PXE Server

Copy the following TFTP configuration files to the /var/lib/tftpboot/ directory.
#cd /usr/share/syslinux/ #cp pxelinux.0 menu.c32 memdisk mboot.c32 chain.c32 /var/lib/tftpboot/
Edit file /etc/xinetd.d/tftp
#vi /etc/xinetd.d/tftp
Enable TFTP server. To d this, change “disable=yes” to “no”.
# default: off
# description: The tftp server serves files using the trivial file transfer \
# protocol. The tftp protocol is often used to boot diskless \
# workstations, download configuration files to network-aware printers, \
# and to start the installation process for some operating systems.
service tftp
{
socket_type = dgram
protocol = udp
wait = yes
user = root
server = /usr/sbin/in.tftpd
server_args = -s /var/lib/tftpboot
disable = no
per_source = 11
cps = 100 2
flags = IPv4
}
Next, create a directory to store CentOS
installation ISO image. and mount the image to that directory as shown
below. I have CentOS 6.5 32bit ISO image on my /root directory.
#mkdir /var/lib/tftpboot/centos6.5
#mount -o loop /var/lib/tftpboot/CentOS-6.5-bin-DVD1.iso /mnt
#cp /mnt/images/pxeboot/vmlinuz, initrd.img /CentOS6.5
Create a apache configuration file for PXE server under /etc/httpd/conf.d/ directory:
#vi /etc/httpd/conf.d/pxeboot.conf
Add the following lines:
Alias /centos6_5 /mnt <Directory /mnt> Options Indexes FollowSymLinks Order Deny,Allow Deny from all Allow from 58.x.x.0/26 </Directory>
Save and close the file.
Then, create a configuration directory for PXE server:
#mkdir /var/lib/tftpboot/pxelinux.cfg
Now, create PXE server configuration file under the pxelinux.cfg:
#vi /var/lib/tftpboot/pxelinux.cfg/default
Add the following lines:
prompt 0
timeout 300
ONTIMEOUT local
Menu title ########## PXE Boot Menu ##########

MENU LABEL ^Hard DIsk
LOCALBOOT 0x80
Configure DHCP Server
Now, we have to configure the DHCP server to work with PXE server.
Edit file /etc/dhcp/dhcpd.conf,
#vi /etc/dhcp/dhcpd.conf
Add the following lines at the end:
allow booting; allow bootp; next-server 58.x.x.50; filename "pxelinux.0";
Save and close the file.
Now, We have come to the end of PXE server configuration. Restart all the services to complete the configuration.
service xinetd restart service httpd restart service dhcpd restart
