Ubuntu PXE Boot Server Step by Step: Everything You Need to Know

Introduction

Welcome to our comprehensive guide on Ubuntu PXE boot server step by step. If you are looking for an efficient way to automate server installations in your network, PXE (Pre-Boot Execution Environment) boot server may be the solution for you. In this article, we will show you how to install and configure a PXE boot server on your Ubuntu system, and discuss its advantages and disadvantages. So, let’s dive in!

What is a PXE Boot Server?

PXE boot server is a network booting technology that allows you to install operating systems and other software over the network without physical media such as CDs or USB drives. This can save you a lot of time and effort, especially if you have a large number of computers to install or update.

How Does PXE Boot Server Work?

When a computer boots up, it sends a request to the network for an IP address and other configuration information. If the network has a PXE boot server, it responds to the request and provides the necessary information, including the location of the boot image. The computer then downloads the boot image from the server and starts the installation process.

What Are the Requirements for PXE Boot Server?

Before we get started, make sure you have the following:

Requirement	Description
Ubuntu system	Any version of Ubuntu with internet access
DHCP server	A DHCP server that can provide IP addresses and network configuration
TFTP server	A TFTP server to serve boot images to the clients
