Deploying operating systems across multiple computers can be a nightmare if done one by one. But what if you could do it all at once, quickly and effortlessly? That’s where FOG Server steps in — a free and open-source solution for network-based OS deployment. And the best part? It’s super easy to install on Ubuntu or Debian with just a bit of terminal magic.

TL;DR

FOG Server lets you clone and deploy OS images to many computers over a network. It’s perfect for IT admins in schools, businesses, or labs. You’ll need Ubuntu or Debian, some network prep, and a little time to spare. Follow this guide for a smooth ride!

What is FOG Server?

FOG (Free Open-source Ghost) is a Linux-based server that takes care of deploying disk images to multiple machines over a network using PXE boot. Think of it as a time-saving machine for IT admins. Imagine setting up a whole lab of desktops… in minutes.

Why Use FOG?

Here’s why people love FOG server:

• It’s free and open-source.
• Supports Windows, Linux, and Mac OS imaging.
• Remote management and task scheduling features.
• Web UI for ease of use.
• No need to install an OS first – PXE boot does the job!

Prerequisites

Before diving into installation mode, make sure you’ve got the essentials:

• A fresh install of Ubuntu 22.04+ or Debian 11+.
• Root (sudo) access.
• Static IP configuration for the server.
• At least 8GB RAM and decent storage if dealing with large images.
• A wired LAN network works best!

Step 1: Update Your System

Always start with updating your packages. Open your terminal and run:

sudo apt update && sudo apt upgrade -y

After updates finish, reboot if prompted.

Step 2: Install Required Packages

FOG requires a few supporting tools. Install them with:

sudo apt install git wget curl net-tools -y

Step 3: Install Apache, PHP, and Required Services

FOG uses Apache and PHP for its web UI, along with other packages. Run:

sudo apt install apache2 php php-mysql php-cli php-gd php-curl php-mbstring php-xml mysql-server -y

Start and enable Apache and MySQL:

sudo systemctl enable --now apache2 mysql

Step 4: Clone the FOG Project

Now it’s time to grab FOG from GitHub:

cd /opt  
sudo git clone https://github.com/FOGProject/fogproject.git  
cd fogproject/bin

Pick your flavor:

• If you’re on Debian: sudo ./installfog.sh -y
• If you’re on Ubuntu: sudo ./installfog.sh -y

This kicks off the interactive installer. Take a deep breath — you’ve got this!

Step 5: Follow the Installer Prompts

The installer asks you some questions. Here’s how to answer them:

• Is this the FOG server? → Yes
• What type of installation? → Normal Installation
• Interface to bind to? → Usually eth0 or enp3s0 (check with ip a)
• Set DHCP server? → Yes, if you don’t have another DHCP server

This can take 10–15 minutes. Don’t worry if it seems to pause once in a while.

Step 6: Configure FOG Web Installer

Once the terminal part finishes, you’ll see a message telling you to go to the web installer:

http://your-server-ip/fog/management

Open that URL in your browser. You’ll see a lovely web-based installer. Click through “Install/Update Now.” That’s it — you’re done!

Step 7: Log Into Your FOG Server

After installing, go to:

http://your-server-ip/fog/management

Default login creds:

• Username: fog
• Password: password

Now you’re inside the FOG Dashboard. Let the clicking begin!

Step 8: Add Your Devices

Time to register some devices to your FOG system:

• Boot the target PC using PXE (make sure network boot is enabled in BIOS).
• FOG will detect the machine and let you register it.

You can give it a name, MAC address, and even assign it an image for deployment later.

Step 9: Create and Upload Your First Image

Let’s save your golden OS image:

1. Install and configure your “perfect” machine — the one you want to clone.
2. Register that host in FOG.
3. Go to the FOG dashboard → Hosts → Your Host → Basic Tasks → Upload Image.

Once uploaded, your image is ready to be deployed to any other computer!

Step 10: Deploy the Image

Deploying is even easier:

• Network boot your target computer.
• Select it from the host list.
• Assign the image you created.
• Click “Deploy” — and let FOG do its thing!

In minutes, your clone is up and running.

Tips & Tricks

• Use groups to bulk-task many hosts together.
• Always set static IPs for both server and clients to avoid confusion.
• Build images for different hardware profiles for best compatibility.
• Back up your images and DB regularly!
