Chapter 3. Registering your system and attaching subscriptions

To use RHUI efficiently and gain access to Red Hat repositories and support, you must register RHUI and attach the relevant subscriptions to your RHUA, CDS, and HAProxy nodes.

3.1. Installing Red Hat Enterprise Linux

To register and attach the subscriptions to your nodes, you must install Red Hat Enterprise Linux (RHEL) on each of them.

Procedure

  1. Navigate to the node on which you wish to install RHEL.

  2. Install RHEL.

    For detailed instructions on how to install RHEL, see Performing a standard RHEL installation.

3.2. Registering nodes

To use RHUI on your system, you must register each node with Red Hat.

Procedure

  • On the RHUA node, enter the following command to register the system: 

    # subscription-manager register --type=rhui --username <admin-example> --password <secret>
Registering to: subscription.rhsm.redhat.com:443/subscription
The system has been registered with ID: <a12b34c5-6d78-9ef1-2345-ghi678jk91l2m>

  • On the CDS and HAProxy nodes, enter the following command: 

    # subscription-manager register --username <admin-example> --password <secret>
Registering to: subscription.rhsm.redhat.com:443/subscription
The system has been registered with ID: <a1b2c3-d4e5-f6g7-2345-hij890klm123>

  • Optional: If your system is already registered, you can override the subscription using the --force option. 

    # subscription-manager register --force

    The new system will be available on the Red Hat Customer Portal, and the new RHUA instance will not have any subscriptions attached to it.

Verification

  1. Navigate to the Red Hat Customer Portal.
  2. Verify that your system is available by locating it within the Customer Portal.

3.3. Attaching a subscription to the RHUA node

The following instructions explain how to attach a subscription to your Red Hat Update Appliance (RHUA) node.

Prerequisites

  • Ensure you have root access to the RHUA node.
