In this hands-on lab, you'll dive into the essential commands for managing services and daemons using the Command Line Interface (CLI). Understanding how to control these elements is not only vital for everyday operations but also for preparing for the Red Hat Certified System Administrator (RHCSA) certification.
In this Lab, You'll Learn How To
-
Manage services and daemons
-
Check the status of specific services
-
Start and stop a service
-
Restart and reload a service
-
Enable and disable services
-
Mask and unmask services
