How to install Cockpit on Rocky Linux 9.2

To install Cockpit on Rocky Linux 9.2

Introduction:

Cockpit is a server management dashboard that provides real-time information on the state of your machine. In addition to CPU load, filesystem statistics, processes, and other data also give access to the system. When you're not signed in to the control panel, Cockpit doesn't use any server resources. The Cockpit service only begins when you go to the control panel and use it.
