Embarking on a journey into the world of Linux system administration can feel daunting, especially with a powerful distribution like Red Hat Enterprise Linux (RHEL). Fortunately, Udemy offers a fantastic resource to guide you through the essentials: ‘Linux Redhat System Administration I – SA1 (RHEL8)’. This course is meticulously designed for anyone aiming to achieve the Linux Certified System Administrator (EX200) certification, a crucial stepping stone for aspiring RHEL professionals.
From the very beginning, the course excels at setting up your learning environment. It provides clear instructions and links for downloading RHEL and virtualization software like VMware Workstation or Oracle VirtualBox. The hands-on approach starts immediately with detailed walkthroughs on creating RHEL 8 templates and installing the OS, both within VMware and VirtualBox. This practical foundation is invaluable for building confidence and familiarity with the system.
The course then seamlessly transitions into the core command-line interface (CLI). You’ll learn to navigate the Bash shell, understand virtual and physical consoles, and even get acquainted with the GNOME 3 desktop environment. The emphasis on command-line file management is particularly strong, covering file system hierarchy, identifying file types, absolute and relative paths, and the crucial differences between soft and hard links. Pattern matching, tilde, brace, and variable expansion are also thoroughly explained, preparing you for efficient command-line operations.
User administration is another area where this course shines. It breaks down user and group concepts, explains different account types, and delves into managing user passwords and the critical `sudoers` file. The numerous practice lab sessions integrated throughout these modules are a standout feature, allowing you to apply what you’ve learned immediately and reinforce your understanding.
File system permissions are demystified, covering attributes, command-line management, and special permissions like Setuid, Setgid, and Sticky bits. Process management is tackled with explanations of load average, the `top` command, and foreground/background process control. The course also provides a solid overview of RHEL 8 features and the modern `systemd`init system, including practical labs on `systemctl` and `journal`.
Security and networking are not overlooked. You’ll learn to configure and secure SSH services, including key-based authentication and customizing configurations. Analyzing and storing logs using `journalctl` and understanding log rotation are covered in detail. Networking concepts, TCP/IP, and practical network interface management (adding, modifying, deleting) are explained clearly. File system mounting and unmounting, along with essential commands like `locate` and `find`, are also part of the comprehensive curriculum.
Finally, the course introduces system monitoring through the web-based Cockpit tool, offering a user-friendly way to analyze server performance. The concluding lecture wraps up the essential topics, leaving you well-prepared for the EX200 exam.
**Recommendation:**
For anyone serious about obtaining the Red Hat Certified System Administrator (RHCSA) certification or simply wanting a robust understanding of RHEL 8 system administration, this Udemy course is an excellent investment. The instructor’s clear explanations, combined with ample hands-on labs, make complex topics accessible and manageable. It strikes a perfect balance between theoretical knowledge and practical application, ensuring you’re not just learning concepts but actively practicing them. Highly recommended!
