How To Manage Remote Servers with Ansible
This book is designed to introduce you to using Ansible to manage your servers. You'll learn how to install and configure Ansible on a control node, and then how to use it to configure and run commands on remote servers. You'll also learn how to collect tasks into complete Playbooks to automate server setup from start to finish. The topics that it covers include how to: - Become familiar with configuration management tools and processes, and the benefits of using them to manage your infrastructure. - Install and configure Ansible on an Ubuntu 20.04 control node, ensuring that your servers are properly set up and that you are able to execute remote instructions through Ansible. - Build inventory files and organize your servers into groups to selectively control how and where Ansible commands are run. - Run Ad Hoc commands to execute individual tasks on one, or multiple remote servers. - Package individual commands into Playbooks that you can use to automate the provisioning of m ...

Robot Operating System (ROS) for Absolute Beginners, 2nd Edition
Start programming your own robots using Robot Operation System (ROS). Targeted for absolute beginners in ROS, Linux, and Python, this guide lets you build your own robotics projects. You'll learn the basic foundation of Ubuntu Linux. Begin with the fundamentals. Installation and useful commands will give you the basic tools you need while programming a robot. Then add useful software applications that can be used while making robots. Programming robots can be done using any of the programming languages. Most popular programming languages are Python and C++. You will incorporate the fundamentals of C++ by learning object oriented programing concepts from example and building C++ projects. Finally, tackle an ROS hands-on project to apply all the concepts of ROS you've learned. The aim of the project is to perform a dead-reckoning using a cheap mobile robot. You can command your robot's position on Rviz and your robot will move to that position! Not only will you learn to program, ...
