RHEL 8

Operating Running Systems

Andrew Mallett

Having already gained some command line experience in RHEL 8, you may want to know how to shut the system down now. This course will teach you how to manage services in RHEL 8 and the complete system.

Administering Linux servers can often be depressing; starting new work on a Monday morning and you realize no one knows the root password. In this course, RHEL 8: Operating Running Systems, you’ll learn to gain full control of your existing RHEL 8 systems. First, you’ll explore the boot process and learn to shut down and reboot systems and restrict user access during maintenance. Next, you’ll discover how to reset root passwords when access is restricted. Finally, you’ll learn to tune the performance of the system to match the requirements you define. When you’re finished with this course, you’ll have the skills and knowledge of Linux system management allowing you to analyze issues, correcting them in an efficient manner.
