👉 Introduction
Welcome to our comprehensive guide on setting up a PXE Boot Server Ubuntu! In today’s fast-paced digital world, we no longer have the time to install operating systems on each computer physically. That’s where the Preboot Execution Environment (PXE) comes in. PXE allows you to boot multiple computers via the network. In this guide, we’ll walk you through the step-by-step process of setting up a PXE Boot Server Ubuntu, including its advantages and disadvantages. Let’s get started!
👉 What is PXE booting?
PXE booting is the process of booting a computer over the network instead of booting using local storage devices. PXE utilizes a client-server architecture, where a PXE-enabled device (client) contacts a PXE server and requests an operating system image, which is then downloaded and booted on the client machine. This eliminates the need for local storage devices, making it an efficient and time-saving method of deploying operating systems and applications on multiple computers.
👉 The advantage of PXE booting
There are several advantages of using PXE booting. Some of these advantages include:
Advantages |
Details |
|---|---|
Time-Saving |
You can install and configure multiple computers at the same time, reducing the installation time significantly. |
Cost Saving |
PXE eliminates the need for physical storage devices like USB drives and DVDs, saving money in the long run. |
Centralized Management |
With PXE, you can manage the installation and configuration of multiple computers from a single server, making it easier to maintain the network infrastructure. |
Efficient |
PXE booting is an efficient way of deploying operating systems and applications, as it eliminates the need for manual intervention. |
👉 The disadvantages of PXE booting
While PXE booting has many advantages, there are some disadvantages as well. These include:
Disadvantages |
Details |
|---|---|
Network Dependency |
PXE booting requires a stable and reliable network connection; otherwise, the process may fail. |
Complex Setup |
PXE booting can be challenging to set up and configure, especially for those who are new to the process. |
Security Risks |
Since PXE booting relies heavily on network connectivity, it can be susceptible to security risks like failing to update the image on the server. |
👉 How to Set up a PXE Boot Server Ubuntu?
Setting up a PXE Boot Server Ubuntu can be a bit tricky, but we’ve broken it down into simple steps, making it easier for you to follow along:
Step 1: Install Ubuntu Server
The first step in setting up a PXE Boot Server Ubuntu is installing Ubuntu Server on a computer that will act as your server. Make sure you have a stable internet connection when installing Ubuntu Server.
Step 2: Install DHCP Server
The next step is installing a DHCP (Dynamic Host Configuration Protocol) server. DHCP is a network protocol that dynamically assigns IP addresses to devices on the network. To install the DHCP server, run the following command:
sudo apt-get install isc-dhcp-server
Step 3: Configure DHCP Server
The next step is configuring the DHCP server to provide an IP address to the PXE client computers. To do this, you need to modify the /etc/dhcp/dhcpd.conf file.
sudo nano /etc/dhcp/dhcpd.conf
Then, add the following lines to the file:
subnet 192.168.1.0 netmask 255.255.255.0 {range 192.168.1.100 192.168.1.200;option broadcast-address 192.168.1.255;option routers 192.168.1.1;option domain-name-servers 192.168.1.1, 8.8.8.8;filename “pxelinux.0”;}
Step 4: Install and Configure TFTP Server
The next step is installing and configuring a Trivial File Transfer Protocol (TFTP) server. TFTP is a simple file transfer protocol used for transferring files over the network.
sudo apt-get install tftpd-hpa
Next, open the /etc/default/tftpd-hpa file and modify the following line:
TFTP_OPTIONS=”–secure”
Step 5: Download and Configure PXE Images
The next step is downloading and configuring the PXE images that you want to deploy on the PXE client computers. You can download the PXE images from the official Ubuntu website.
Then, extract the downloaded files and copy them to the /var/lib/tftpboot/ directory:
sudo cp -r ~/Downloads/netboot/* /var/lib/tftpboot/
Step 6: Configure the PXE Boot Menu
The last step is configuring the PXE boot menu, which allows you to choose which operating system to boot on each client computer. To configure the PXE boot menu, modify the /var/lib/tftpboot/pxelinux.cfg/default file:
sudo nano /var/lib/tftpboot/pxelinux.cfg/default
Then, add the following lines to the file:
default menu.c32prompt 0timeout 50menu title PXE Boot Menulabel 1menu label Ubuntu Server 20.04 LTSkernel ubuntu-installer/amd64/linuxappend initrd=ubuntu-installer/amd64/initrd.gz priority=critical locale=en_US console-setup/ask_detect=false keyboard-configuration/layoutcode=us netcfg/dhcp_timeout=60 netcfg/use_autoconfig=true
👉 Frequently Asked Questions (FAQs)
Q1: What is a PXE server?
A PXE server is a server that is configured to allow multiple computers to boot using the network. It provides the necessary files and configuration settings needed for the client computers to boot over the network instead of using local storage devices.
Q2: What are the benefits of using a PXE server?
Using a PXE server provides several benefits, including time-saving, cost-saving, centralized management, and efficient deployment of operating systems and applications.
Q3: How does PXE booting work?
PXE booting works by booting a computer over the network instead of using local storage devices. The computer contacts a PXE server and requests an operating system image, which is then downloaded and booted on the client machine.
Q4: What is a DHCP server?
A DHCP server is a network protocol that dynamically assigns IP addresses to devices on the network.
Q5: What is a TFTP server?
A TFTP server is a simple file transfer protocol used for transferring files over the network.
Q6: What is a PXE image?
