It has been published on the LPI-Japan website. This textbook is also useful as preparation for learning the Linux technical certification exam "LinuC."

The PDF version (free), ePub version (free), and Kindle version (paid) will be available starting July 1, 2026, and pre-orders for the printed version (paid) will begin on July 1, 2026.

Background of Release and Main Features

Background of This Textbook's Release

In recent years, Linux has been increasingly utilized in fields such as cloud, AI, containers, and data science. Among these, Ubuntu is one of the Linux distributions widely used, particularly in development and cloud environments.

According to the "Stack Overflow Developer Survey 2025" (Note 1), one of the world's largest developer surveys, Ubuntu is used by many developers for both personal use (27.8%) and professional use (27.7%).

Ubuntu is widely used as a Linux virtual machine in public clouds such as AWS and Microsoft Azure, and is also adopted for various purposes such as container base images, generative AI/LLM development environments, and machine learning environments utilizing NVIDIA GPUs.

Furthermore, the use of Ubuntu is expanding in educational institutions such as universities and vocational schools, increasing the demand for learning materials that are relevant to actual usage environments.

In response to these market trends and requests from the education sector, LPI-Japan has developed and released the Ubuntu edition of the "Linux Server Construction Standard Textbook" in cooperation with the LinuC Open Network Community (Note 2). This allows users to choose their learning environment from both the AlmaLinux edition and the Ubuntu edition, depending on their usage environment and learning objectives.

Main Features of This Textbook

1. Practical Learning Environment Using Ubuntu 24.04 LTS

In addition to the conventional AlmaLinux edition, this material adopts Ubuntu 24.04 LTS (Server) as the learning environment. By having students install Ubuntu themselves and learn while actually executing commands, they can acquire knowledge and skills directly applicable to their work.

2. Deep Understanding of Server Mechanisms Through Hands-on Practice

Students can learn server construction techniques included in the LinuC Level 2 (Exams 201 and 202) curriculum through actual construction exercises. By performing web access to the constructed servers and sending/receiving emails, they can experientially understand the operating principles of servers and the mechanisms of various protocols.

3. "Ever-Evolving Textbook" Co-created with the Community

Since the first edition was released in 2009, this textbook has been revised based on feedback from many users and IT professionals in the field. Going forward, we will continue to update it to support the latest technologies and expand its content through reviews and discussions within the LinuC Open Network Community, where anyone can participate.

4. Free Publication Under Creative Commons License

This textbook is published under a Creative Commons license (Note 3). The PDF and ePub versions can be used free of charge by anyone, regardless of the purpose, including school education, corporate training, and individual learning.

Comments from the Author

Takahiro Kugei, LinuC Evangelist / Zeus Enterprise Co., Ltd.

Do you feel that Linux operations are difficult and server construction is out of reach?

This book is a must-read for you.

Based on Ubuntu 24.04 LTS, you can learn about servers used on the internet, such as web, DNS, and mail, by actually doing it.

To prevent frustration, command operations are minimized, prioritizing the "It worked!" feeling of accomplishment and experience.

For command acquisition, we recommend using it in conjunction with the "Linux Standard Textbook" from the Standard Textbook series, but first, please experience the fun of server construction with this book.

We hope that this first step will contribute to your technical skill improvement and a bright future as an engineer.
