Linux Mastery With Practical Approach & Level Up Your Career

It looks like you've outlined a comprehensive curriculum for someone looking to gain expertise in various Linux administration tasks, including setting up and managing containerized applications, configuring web servers (Apache), understanding DNS, automating administrative tasks with Ansible, managing SELinux security, and setting up a Samba server.

Here's a suggested approach to tackle this curriculum:

1. Understanding the Basics: Start by getting familiar with the basics of Linux administration. This includes understanding the file system, users and groups, package management, and basic command-line operations.

2. Containerization: Dive into containerization technologies like Docker or Podman. Learn how to create, manage, and deploy containers, as well as how to map host ports to containers, and how to stop, restart, and remove containers as needed.

3. Web Server Configuration: Install and configure Apache (or another web server of your choice), set up a simple web page, and understand the configuration files involved. Learn about order directives (Allow, Deny), indexing options, and how to use .htaccess for directory-specific configurations.

4. SSL/TLS: Secure your web server with SSL/TLS for encrypted communication, ensuring that data transmitted is protected.

5. DNS Server Setup: Learn how DNS works, set up a DNS server, and understand the hierarchy of domains. Configure zones, troubleshoot common issues, and understand the importance of DNS in network services.

6. Automation with Ansible: Start setting up Ansible for automating tasks on your servers. Learn about inventories, playbooks, modules, and how to write ad hoc commands. Understand Ansible's idempotent nature and how to use it to maintain configuration states.

7. SELinux Security: Get to grips with SELinux, understand its contexts, modes, booleans, and inheritance. Learn how to troubleshoot issues with audit logs and apply necessary configurations to ensure system security.

8. Samba Server Configuration: Finally, learn how to install and configure a Samba server for file sharing between Linux and Windows clients. Understand the different types of shares (public and private), how to mount them, and how to secure your resources.

9. Practical Labs: Throughout each section, perform hands-on labs to apply what you've learned in real-world scenarios. This will solidify your understanding and give you practical experience.

10. Review and Practice: After completing the lab sessions, review all the concepts covered. Practice by setting up a complete system that incorporates all the components you've studied, ensuring you can manage everything from containerization to Samba in a cohesive environment.

11. Interview Preparation: Use interview questions and answers to prepare for potential job interviews. This will help you articulate your knowledge and experience effectively.

By following this curriculum and dedicating time to each topic, you'll build a strong foundation in Linux system administration, with a focus on modern practices and tools. Remember to keep the lab environment consistent throughout your learning process to avoid confusion and to allow for a deeper understanding of the interactions between different services and configurations.
