We have already shown about PXE server installation and configuration on CentOS 6.5 a couple of days before. Today, let us setup and configure PXE server on Ubuntu 14.04 server.

Scenario

My test box(pxe server) details are given below:

  • OS: Ubuntu 14.04 LTS server.
  • IP Address: 192.168.1.250/24.

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 necessary packages for setting up PXE environment:

sudo apt-get install apache2 tftpd-hpa inetutils-inetd

Configure PXE Server

Edit file /etc/default/tftpd-hpa,

sudo nano /etc/default/tftpd-hpa

Add the following lines to enable TFTP server.

[...]
RUN_DAEMON="yes"
OPTIONS="-l -s /var/lib/tftpboot"

Then, edit file /etc/inetd.conf,

sudo nano /etc/inetd.conf

Scroll down to the end, and modify or add the following line.

tftp    dgram   udp    wait    root    /usr/sbin/in.tftpd /usr/sbin/in.tftpd -s /var/lib/tftpboot

Save and close the file. If you use IPv6, please change the word udp to udp4.

Restart tftp service:

sudo /etc/init.d/tftpd-hpa restart

Copying Ubuntu Installation files to PXE Server

You can either mount the Ubuntu Installation ISO image and copy them to your PXE server or can directly copy the files from your Installation CD/DVD.

For the testing purpose, I want to deploy the Ubuntu 14.04 server on my PXE client, so I mounted the ISO image on /mnt directory. I already have the ISO image on my home directory, so I ran the following command to mount it on /mnt directory.

sudo mount -o loop /home/sk/ubuntu-14.04-server-i386.iso /mnt

The Ubuntu 14.04 ISO image has been mounted successfully. Now, go to the /mnt directory, and copy the required files from the ISO image to /var/lib/tftpboot/ directory.

cd /mnt
sudo cp -fr install/netboot/* /var/lib/tftpboot/

Create a directory called ubuntu in the apache root document folder.

sudo mkdir /var/www/ubuntu

Copy all the files from the Ubuntu ISO.

sudo cp -fr /mnt/* /var/www/ubuntu/

Now, edit file /var/lib/tftpboot/pxelinux.cfg/default,

sudo nano /var/lib/tftpboot/pxelinux.cfg/default

Add the following contents at the end. Make sure you’ve replaced the IP address with your own.

[...]
label linux
        kernel ubuntu-installer/i386/linux
        append ks=http://192.168.1.250/ks.cfg vga=normal initrd=ubuntu-installer/i386/initrd.gz
ramdisk_size=16432 root=/dev/rd/0 rw  --

Note: If you use 64 edition, you should change the kernel path in the about directory with correct path.

Save and close the file.

Configure DHCP Server

Now, we have to configure the DHCP server to work with PXE server.

Edit file /etc/dhcp/dhcpd.conf,

sudo nano /etc/dhcp/dhcpd.conf

Add the following lines at the end:

allow booting;
allow bootp;
option option-128 code 128 = string;
option option-129 code 129 = text;
next-server 192.168.1.250;
filename "pxelinux.0";

Save and close the file.

Now, We have come to the end of the PXE server configuration. Restart DHCP server.

sudo service isc-dhcp-server restart

Congratulations! We have completed the PXE server configuration.

PXE Client Configuration

The client may be any system that has network boot enabled option (PXE boot). You can enable this option in your Bios settings.

Due to lack of resources, I have created a Virtual Machine client on my Oracle VirtualBox.

Open up the Oracle VirtualBox. Click on the New button in the menu bar.

Oracle VM VirtualBox Manager_001

Enter the Virtual machine name.

Create Virtual Machine_002

Enter the RAM size to the Virtual machine.

Create Virtual Machine_003

Select “Create a virtual hard drive now” option and click Create.

Create Virtual Machine_003

Select the Virtual hard drive file type. If you don’t know to what to select, leave the default option and click Next.

Create Virtual Hard Drive_005

Select whether the new virtual hard drive file should grow as it is used or if it should be created as fixed size.

Create Virtual Hard Drive_006

Enter the Virtual hard drive size.

Create Virtual Hard Drive_003

That’s it. Our Virtual Client machine has been created. Now, we should make the client to boot from the network. To do that, go to the Vitual machine Settings option.

Oracle VM VirtualBox Manager_004

Select the System tab on the left, and Choose Network from the boot order option, and un-check all the other options on the right side.

Ubuntu 14.04 PXE Client - Settings_005

Then, go to the Network tab and select “Bridged Adapter” from the “Attached to” drop down box.

Ubuntu 14.04 PXE Client - Settings_006

Once you done all the above steps, click OK to save the changes. That’s it. Now power on the Virtual client system. You should see the following screen.

Ubuntu 14.04 PXE Client [Running] - Oracle VM VirtualBox_007

That’s it. The rest of the installation is same as the way we do in local installation. Start installing Ubuntu on your client using the PXE server.

Ubuntu 14.04 PXE Client [Running] - Oracle VM VirtualBox_008

Good luck!
