Chapter 2. Registration, attaching, and removing subscriptions in Subscription Manager

Before you can receive support for a Red Hat product, the system needs to be registered and attached to the subscription. User systems can be registered to Red Hat Subscription Management during the first boot of the machine, as well as after the machine has been configured. You can also unregister the system if it no longer needs to be managed using that product.

2.1. Registering and attaching a system in the Subscription Manager user interface

  1. Open the Subscription Manager user interface:
    [root@server ~]# subscription-manager-gui
  2. Select the product you need to register, and click the Register button.
  3. By default, subscription Manager registers your system against the Red Hat Customer Portal. If you use a different registration proxy, configure it here. When you are ready to proceed, click the Next button.
  4. Enter your credentials for the Red Hat Customer Portal, and enter a name to differentiate the system from others attached to your account. Click Register.
  5. Click Attach to attach the system to the account. By default, Subscription Manager automatically attaches the system to a subscription that matches the system architecture.


When auto-attaching a system, the subscription service looks at whether the system is physical or virtual, as well as how many sockets the system has:
  • A physical system usually consumes two entitlements, whereas a virtual system consumes one.
  • One entitlement is consumed per two sockets on a system.
