DevOps Foundation: Linux & Systems Hands-On is built for learners who are ready to stop reading about Linux and start working with it. Across three focused modules, you'll tackle real-world scenarios covering Linux system administration, automation, and web server and database deployment.

This course uses a Practice-and-Compare methodology. You'll attempt each hands-on lab independently, then watch a solution video that walks through the expert workflow — explaining the reasoning behind every decision, not just the commands. This approach helps you find gaps in your own thinking and correct them in real time. You'll work with tools used across the industry: configure SSH hardening and SELinux policies, write Bash scripts and automate tasks with Ansible, deploy Nginx and Apache web servers, secure traffic with SSL/TLS, and manage PostgreSQL and MariaDB databases. By the end, you'll have hands-on experience with the core systems skills expected in Linux administrator and DevOps engineer roles. Who this is for: Learners with basic Linux familiarity who are ready to move beyond theory and build applied, job-ready technical skills. This course is ideal for learners with basic Linux familiarity who are ready to move beyond theory and build applied, job-ready technical skills.

This module focuses on the core identity of a Linux administrator. You will learn to manage users, secure the gateway to your server via SSH, and ensure system tasks run automatically and securely.

Frequently asked questions

This course is designed for learners who already have basic Linux familiarity — such as comfort navigating the command line and understanding file permissions. If you are completely new to Linux, building foundational knowledge first will help you get the most from the labs.

You'll gain hands-on experience with SSH, SELinux, Cron, Bash, Ansible, IPtables, Nginx, Apache, Tomcat, PHP-FPM, MariaDB, PostgreSQL, Git, and SSL/TLS — a broad set of tools that appear regularly in Linux administrator and DevOps engineer job requirements.

Each topic follows a three-step sequence: you read the concept, attempt the hands-on lab on your own, and then watch a solution video that deconstructs the expert approach. This method encourages productive problem-solving and helps you identify and fix your own blind spots immediately.

Most courses emphasize watching and listening. This course prioritizes doing. Every concept is anchored to a practical lab, and every lab is paired with a solution video that shows professional-level thinking — not just the correct answer. The focus is on building the execution habits and confidence that come from real practice.

This course builds applied skills relevant to roles such as Linux System Administrator, DevOps Engineer, Site Reliability Engineer (SRE), and Cloud Infrastructure Engineer. The tools and scenarios covered reflect real responsibilities in these positions across technology, finance, and enterprise IT environments.

Module 1 covers Linux user management, SSH hardening, SELinux, script permissions, and Cron automation.

Module 2 covers Ansible, Bash scripting, Tomcat, MariaDB troubleshooting, network services, IPtables, and process troubleshooting.

Module 3 covers Nginx, Apache, PostgreSQL, LAMP stack configuration, SSL/TLS, PHP-FPM, load balancing, and Git repository setup.

To access the course materials, assignments and to earn a Certificate, you will need to purchase the Certificate experience when you enroll in a course.
