Course Description

Step into real-world Linux administration with a practical, beginner-friendly course focused on Red Hat Enterprise Linux 7. Designed for anyone aiming to work in IT support, system administration, or infrastructure roles, this training helps you move from basic familiarity to confident daily command-line and system management skills. You will start from the ground up by setting up the environment and completing a proper RHEL 7 installation, including common virtual machine improvements that make practice smoother and more reliable.

As you progress, you will learn how to make a Linux system feel like your own while keeping it professional and manageable. The course explores essential desktop and login customizations, hostname configuration, and core usability adjustments that are often needed in labs and workplaces alike. These hands-on tasks build the habit of navigating Linux settings thoughtfully, understanding what changes affect the system, and keeping configuration consistent across machines.

A major focus is user and group administration, a key responsibility in any multi-user Linux environment. You will work through concepts and commands used to create and manage accounts, control access, and apply policies safely. From fundamental configuration files to advanced user creation and modifications, you will develop the ability to administer access in a controlled, auditable way.

Security and access management continue with a deep, practical look at permissions. You will gain clarity on ownership, groups, symbolic links, default permission behavior, and special permission bits that frequently appear in enterprise scenarios. You will also learn to use Access Control Lists to handle exceptions cleanly when traditional permissions are not enough, helping you design access rules that match real team and project needs.

To round out system administration skills, the course covers networking setup and troubleshooting through multiple approaches, including command-line tools and interfaces. You will work with package management by configuring yum repositories and clients, and you will build foundational service administration skills through DHCP and SSH configuration, including key-based authentication for secure, efficient access. By the end, you will have a well-rounded RHEL 7 workflow that translates directly to lab practice, interviews, and everyday IT operations.
