In the ever-evolving landscape of network management, the need for efficient and centralized deployment solutions is paramount. One such solution that stands out is the PXE (Preboot Execution Environment) server, a powerful tool for automating operating system installations across multiple systems. This article will guide you through the process of creating a PXE server in CentOS 7, ensuring a seamless and efficient deployment experience.

Understanding PXE Server

PXE servers play a pivotal role in network environments by allowing machines to boot and install operating systems over the network. This eliminates the need for physical installation media, making it a preferred choice for large-scale deployments. The mechanism involves a combination of DHCP (Dynamic Host Configuration Protocol) and TFTP (Trivial File Transfer Protocol) to facilitate the boot process.

Requirements for Setting Up PXE Server on CentOS 7

Before diving into the setup process, it’s crucial to ensure that your hardware, software, and network configurations meet the necessary requirements. This includes specific hardware specifications, software prerequisites, and network settings that will enable a smooth PXE server setup.

Installation of Required Packages

To kickstart the PXE server setup, you’ll need to install a set of essential packages on your CentOS 7 machine. This includes DHCP server, TFTP server, and other dependencies. Ensuring that all packages are properly installed and checking for any missing dependencies is crucial for a hassle-free installation.

Configuring DHCP Server for PXE

Setting up the DHCP server is a crucial step in the PXE server configuration. This involves configuring DHCP options to inform client machines about the location of the TFTP server and the boot image. Proper DHCP configuration ensures that systems attempting to boot from the network receive the necessary information for PXE boot.

TFTP Server Setup

The TFTP server is responsible for transferring the necessary files for PXE boot to client machines. Installing and configuring the TFTP server on CentOS 7, along with ensuring proper file permissions, is essential for a successful PXE server setup.

Creating PXE Boot Images

Generating boot images for different operating systems and customizing them according to your network requirements is the next step. This allows you to deploy various operating systems seamlessly through the PXE server.

Configuring PXE Menu

Creating a user-friendly menu for PXE boot enhances the overall experience. Adding multiple boot options to the menu ensures flexibility for users, allowing them to choose the desired operating system or deployment configuration.

Testing PXE Boot

After the initial setup, it’s crucial to verify the functionality of the PXE server. This step involves testing PXE boot on client machines and troubleshooting common issues that may arise during the process.

Securing PXE Server

Implementing security measures to protect the PXE server from potential vulnerabilities is paramount. Regularly updating the server and monitoring for any suspicious activities contribute to a secure PXE environment.

Scaling PXE Server for Larger Networks

For organizations with larger networks, scaling the PXE server becomes essential. This section discusses strategies for expanding PXE server capacity and considerations for load balancing.

Benefits of Using CentOS 7 for PXE Server

CentOS 7 stands out as a reliable operating system choice for PXE server setups. This section explores the advantages of using CentOS 7 in comparison to other operating systems, highlighting its stability and robust features.

Common Pitfalls and How to Avoid Them

Identifying and addressing potential challenges in PXE server setups is crucial for a smooth operation. This section provides insights into common pitfalls and offers solutions to prevent them.

Best Practices for PXE Server Maintenance

Maintaining the health of your PXE server is an ongoing task. This section outlines regular maintenance tasks and proactive measures to monitor and address potential issues before they impact the network.


In conclusion, setting up a PXE server in CentOS 7 opens doors to efficient and streamlined operating system deployments. The combination of DHCP, TFTP, and user-friendly configurations makes PXE a valuable asset in network management. Explore the possibilities and empower your network with a centralized deployment solution.
