Registering a RHEL system

For Red Hat Enterprise Linux machines, the subscription-manager solution allows users of RHEL to register their software, as well as download Red Hat tested and certified software, updates, and upgrades for RHEL. In this section, you’ll learn how to register and enable your Red Hat subscription to install any package on your system.

During the install process you already registered your RHEL system or are using a pre-registered lab, but you may still want to learn how to do so from the CLI.

Register and Activate a Red Hat Subscription

In order to register your RHEL machine to the Customer Portal, use the subscription-manager command with your credentials like so. The --auto-attach parameter enables the subscription at the same time.

subscription-manager register --username <username> --password <password> --auto-attach

The RHEL system sould confirm your registration with an output similar like so.

The system has been registered with ID: <id>
The registered system name is: localhost.localdomain

Unregister a Red Hat Subscription

If you need to unregister your RHEL machine to re-register with a different account or for any other reason, use the following command.

subscription-manager unregister
