Linux from Zero

From your first command to your own server and AI assistant

Ovanap Team

Cover of Linux from Zero: the title above a terminal window running pwd, ssh, systemctl and ollama

Learn to run a computer by typing to it, rent and lock down your own server, put a website on it with HTTPS — and then run your own AI assistant there. No experience needed: a Windows PC and some curiosity are enough.

Buyers occasionally get new articles and updates by email — when there's something worth sending. No schedule promised.

One path, three stages

This isn't a command reference. Every chapter builds only on what you've already learned, so you go in order: from your own computer, to your own server, to your own AI assistant.


              john@mint:~$ pwd
              /home/john
            
              john@mint:~$ ssh admin@203.0.113.10
              
            
              admin@vps:~$ ollama run llama3.2
              >>> Hello! How can I help?

Your computer Chapters 1–13
In a safe virtual machine you learn the terminal, files, users and permissions, installing software, processes and the system logs.
Your server Chapters 14–22
You rent a VPS, log in over SSH with a key, shut what needs shutting and put a website online with your own domain and HTTPS. Then backups, Bash, Git and Docker.
Your AI assistant Chapters 23–25
You learn how language models work, what tokens and API keys are and what they cost — then run your own AI service, on a local model or through an API.

And Chapter 26 teaches the thing you'll always need: when something breaks, finding out why — methodically, without panic.

What you'll be able to do

The book promises little, but means it: fifteen things you'll do yourself, with your own hands.

Run your own computer

Understand what an operating system is and why Linux matters.
Work in the terminal — talk to the system in text, not just with a mouse.
Manage files and folders safely.
Manage users and permissions.
Install and update software, and find and stop a program that's stuck.
When something breaks, find the cause in the system logs.

Run your own server

Understand how networks work: IP addresses, domain names and ports.
Rent your own server, connect to it securely over SSH and set it up.
Run a website on it with your own domain and a secure HTTPS connection.
Make backups — and prove you can restore from them.
Automate repetitive work: write scripts and schedule tasks.
Track file versions with Git.
Run programs in containers with Docker.

Run your own AI assistant

Understand how large language models work, what a token and an API key are, and what it all costs.
Run an open AI model on your own server or computer, and bring everything you've learned together in one working project.

How the book teaches

A command in this book is never a magic spell. Each one has a number and tells you what you do, why, what changes and what the risk is. Here's the very first, from Chapter 4 — exactly as it is printed in the book.

Command 4.1

pwd – where am I

$ pwd

/home/john

From Chapter 4, “The Terminal: Your First Conversation with the System”

What you do: type pwd and press Enter.
Why: you want to know where in the file system you are standing.
What changes: nothing – the system only prints a path.
Risk: none.

Mistakes are safe here

Every early experiment happens in a virtual machine — a separate computer running inside yours. If something goes wrong, you roll it back and try again. Your real computer is never touched.

Boxes alongside the text

Important: Something worth remembering before you move on.
Dangerous command: A command that can delete or change something permanently. It always comes with a warning and a way back.
Undo: How to reverse what you did.
Check: A short action that confirms everything worked.
Common mistake: A mistake beginners often make, and why it happens.
Try it: A small task you do right here and now.

Who it's for

This book is for you if

you use Windows and a browser but have never opened a terminal;
you want to understand what happens behind the windows, not just click buttons;
you want your own website, server or AI assistant — running on your computer, not someone else's;
you're worried about breaking something — which is why every risky step comes with a way back.

What you won't find

A programming course: there's as much Bash as you need to automate everyday jobs, and no more.
Hacking techniques: the book teaches defense and safe habits.
Kubernetes or enterprise architecture.

26 chapters. We have grouped them here by stage of the journey; each ends with a “What you can do now” recap and, almost always, a lab.

Why we wrote this book

Our story with Linux began twenty years ago, with a beginner's book on Red Hat Linux from a Lithuanian series much like “For Dummies”. We opened the black screen and fell for it: the terminal, and the feeling of finally cracking a problem.

We have worked with Linux every day since, and the feeling has stayed.

We believe these skills still matter — maybe more than ever — in the age of AI. AI can write the commands, but someone has to understand what they do, own the server, and fix it when it breaks. We wrote this book so that someone can be you.

Questions

Do I really need no experience at all?

None. The book starts with what the very first terminal window looks like and takes nothing for granted. If you can use a Windows PC and a browser, you have everything you need.

What kind of computer do I need?

An ordinary Windows PC. You install Linux Mint in a virtual machine, so your own system stays untouched. For the server chapters you rent a VPS — the book explains how to choose one.

How do I get the book?

Once you've paid, we prepare your personal PDF and email you a download link within a few minutes. The link works for 30 days and up to 5 downloads.

The email never arrived. What now?

Check your spam folder first. If it isn't there, ask for a new link — we'll send it to the same address you used at checkout.

Why no DRM or password on the PDF?

Because they only inconvenience people who paid, and don't stop anyone who wants to get around them. Instead, every copy is marked with the buyer's name and order number.

Can I get a refund?

Digital content is delivered straight away, so once you agree to that at checkout, the 14-day right to cancel no longer applies. But if the file won't open or the link doesn't work and we can't fix it, you get your money back. Email hello@ovanap.no.

Can I get an invoice?

Yes — email hello@ovanap.no, or simply reply to the email with your link, and we will send one (with your company details, if you need them).

Is there a Lithuanian edition?

Yes — the book was written in Lithuanian first, as “Linux nuo nulio”. You can switch language at the top of this page.
