Welcome to the Ubuntu Server Guide! Here you can find information on how to install and configure various server applications. It is a step- by-step, task-oriented guide for configuring and customizing your system. This guide assumes you have a basic understanding of your Ubuntu system. Some installation details are covered in Chapter 2, Installation [p. 3], but if you need detailed instructions installing Ubuntu please refer to the Ubuntu Installation Guide 1 .

Linux Management

Running your own dedicated server has become simpler and less expensive. These days, administering a development server or hosting sites and web applications has become part of the job for many developers. Webmin is an easy-to-use web-based tool which makes getting started with new administrative tasks and performing common jobs more simple and efficient. Webmin Administrator's Cookbook offers practical, step-by-step recipes covering a range of topics related to setting up and administering a server. The book will show you how Webmin can help you configure an Apache web server, MySQL server, or PostgreSQL database server, as well as how to set up web applications running in PHP or Python.

Manage and deploy Docker services to containerize applications efficiently

Get started with Docker, the Linux containerizing technology that has revolutionized application sandboxing. With this book, you will be able to learn how to use Docker to make your development faster and your deployment of applications simpler. This guide will show you how to build your application in sandboxed Docker containers and make them run everywhere—your development machine, your private server, or even on the cloud, with a fraction of the cost of a virtual machine. Build a PaaS, deploy a cluster, and so on, all on your development setup.

The Docker Book is for developers, sysadmins, and DevOps-minded folks who want to implement Docker™ and container-based virtualization.

There is an expectation that the reader has basic Linux/Unix skills and is familiar with the command line, editing files, installing packages, managing services, and basic networking.

Among the many configuration management tools available, Ansible has some distinct advantages - it's minimal in nature, you don't need to install anything on your nodes, and it has an easy learning curve. This practical guide shows you how to be productive with this tool quickly, whether you're a developer deploying code to production or a system administrator looking for a better automation solution. Author Lorin Hochstein shows you how to write playbooks (Ansible's configuration management scripts), manage remote servers, and explore the tool's real power: built-in declarative modules. You'll discover that Ansible has the functionality you need and the simplicity you desire.

Ansible combines configuration management, orchestration, and parallel command execution into a single tool. Its batteries-included approach and built-in module library makes it easy to integrate it with cloud platforms, databases, and notification services without requiring additional plugins. Playbooks in Ansible define the policies your systems under management enforce. They facilitate effective configuration management rather than running ad hoc scripts to deploy complex applications.

Playbooks in Ansible define the policies your systems under management enforce. They facilitate effective configuration management rather than running ad hoc scripts to deploy complex applications. This book will show you how to write a blueprint of your infrastructure encompassing multi-tier applications using Ansible's playbooks. Beginning with the basic concepts such as plays, tasks, handlers, inventory, and the YAML syntax that Ansible uses, you will see how to organize your code into a modular structure. Building on this, you will master techniques to create data-driven playbooks with variables, templates, logical constructs, and encrypted data. This book will also take you through advanced clustering concepts such as discovering topology information, managing multiple environments, and orchestration.

Ansible is an open source software platform for configuring and managing computers. It provides a clear and concise way to manage the configuration of your Linux infrastructure. This book is a step-by-step guide that provides you with the knowledge you require to effectively manage your systems in a simple, quick, and maintainable way, with real-world examples.

This book is a step-by-step guide that provides you with the knowledge you require to effectively manage your systems in a simple, quick, and maintainable way, with real-world examples. You will begin by learning the basics of Ansible and then move on to exploring more advanced topics. You will then learn the basic and complex operations of playbooks and interact with modules to manage Windows machines and deploy them. You will also get acquainted with Ansible's more advanced features such as serially updating machines, delegating tasks to other machines, advanced uses of variables, looping and conditions, copying whole directories, and using filters to process variables. Towards the end of the book, you will learn how to increase the functionality of Ansible itself by writing your own modules and plugins.

Ansible

As data centers grew, and hosted applications became more complex, administrators realized they couldn’t scale their manual systems management as fast as the applications they were enabling. That’s why server provisioning and configuration management tools came to flourish. Server virtualization brought large-scale infrastructure management to the fore, and the number of servers managed by one admin (or by a small team of admins), has grown by an order of magnitude. Instead of deploying, patching, and destroying every server by hand, admins now are expected to bring up new servers, either automatically or with minimal intervention. Large-scale IT deployments now may involve hundreds or thousands of servers; in many of the largest environments, server provisioning, configuration, and decommissioning are fully automated.
