Chapter 2. Connect and register systems to Red Hat services

To register your RHEL system to Red Hat services, you must establish your system’s identity in the Hybrid Cloud Console. One of the ways that you can do that is by using the recommended rhc client.

2.1. System registration with the rhc client
Link kopieren

Before configuring your system to connect using the rhc client, review the configuration in Red Hat Hybrid Cloud Console > Red Hat Lightspeed > Inventory > System Configuration > Remote Host Configuration (RHC). The remote host configuration manager settings affect how Red Hat Lightspeed remediations function with the system.

2.2. Register RHEL 10 systems
Link kopieren

You can register your RHEL 10 system by using the remote host configuration (rhc) client to connect to Red Hat services with the default feature levels.

This connection enables all available features: access to Red Hat content, analytics for Red Hat Lightspeed, and remote management. You can also disable any of the default feature levels.

Prerequisites

Procedure

  1. Open a terminal window.

  2. To register the system with the default feature levels and ensure the system can execute remediations and tasks from Red Hat Lightspeed, enter the following commands: 

    # rhc connect --activation-key=<activation_key> --organization=<organization_ID>
    Copy to Clipboard Toggle word wrap 
    # dnf install -y rhc-worker-playbook
    Copy to Clipboard Toggle word wrap

  3. Optional: To disable any of the features while you register your system, enter the following command: 

    # rhc connect --activation-key=<activation_key_name> --organization=<organization_ID> --disable-feature <feature>
    Copy to Clipboard Toggle word wrap

    • Where you can replace feature with:

      • content - Provides access to Red Hat CDN repositories.
      • analytics - Enables data collection for Red Hat Lightspeed.

      • remote-management - Establishes an additional MQTT network connection to Red Hat services for remote execution of certain actions from the Red Hat Hybrid Cloud Console.

        Example

        To register your system with remote management disabled, but allow the system access to RHEL content and data for Red Hat Lightspeed analytics, enter: 

        # rhc connect --activation-key=<activation_key_name> --organization=<organization_ID> --disable-feature remote-management
        Copy to Clipboard Toggle word wrap

Verification

  • To confirm the active features when registering with default options: 

    # rhc status
    Copy to Clipboard Toggle word wrap 
    Connection status for hostname.example.com:
✓ Connected to Red Hat Subscription Manager
✓ Content ... Red Hat repository file generated
✓ Analytics ... Connected to Red Hat Lightspeed
✓ Remote Management ... The yggdrasil service is active
    Copy to Clipboard Toggle word wrap

  • To confirm the active features with remote-management disabled: 

    # rhc status
    Copy to Clipboard Toggle word wrap 
    Connection status for hostname.example.com:
✓ Connected to Red Hat Subscription Manager
✓ Content ... Red Hat repository file generated
✓ Analytics ... Connected to Red Hat Lightspeed
[ ] Remote Management ...  The yggdrasil service is inactive
    Copy to Clipboard Toggle word wrap
    Important

    To use remote management, you must enable the yggdrasil daemon. When yggdrasil is inactive, remote management is also inactive.

2.2.1. Customize feature levels for RHEL 10 systems
Link kopieren

If you have a RHEL 10 system, you can use remote host configuration (rhc) to set feature levels when registering with the Red Hat Hybrid Cloud Console.

By default, rhc connects your systems with the remote management feature level. This feature level includes access to RHEL content, analytics for Red Hat Lightspeed, and remote management (remediations and tasks services). If you want to opt out of any of these features, you can disable them when you register your systems.

Note

Customizing feature levels functionality is only available with Red Hat Enterprise Linux version 10.

See the following table for more details about feature levels:

Access to Red Hat content

Content

This feature level provides access to content in the Red Hat Content Delivery Network (CDN). With this feature level enabled, you can install and update packages.

Analytics for Red Hat Lightspeed

Analytics

This feature level collects data from your system using the insights-client and sends it to the Red Hat Hybrid Cloud Console. Then, Red Hat Lightspeed analyzes your data and returns recommendations. You must have the content feature enabled to use the analytics feature.

Remote Management (Default)

remote-management

With this feature level enabled, you can use the remediations and tasks services. You must have the content and analytics features enabled to use the remote management feature.

2.3. Register RHEL 9 systems

If you have a Red Hat Enterprise Linux version 9 system, you can use remote host configuration (rhc) to register your system:

Prerequisites

Procedure

  • Open your command-line interface (CLI), and run the following commands on your client system: 

    # rhc connect --activation-key=<activation_key_name> --organization=<organization_ID>
    Copy to Clipboard Toggle word wrap 
    # dnf install -y rhc-worker-playbook
    Copy to Clipboard Toggle word wrap

Verification

Enter the following command in your CLI: 

# rhc status

2.5. Handle legacy and conversion registrations
Link kopieren

Register and connect RHEL 8.7 and earlier systems, or convert specialized systems like CentOS 7 to RHEL, by using legacy clients (subscription-manager, insights-client). You can still ensure all your non-standard hosts are reporting to Red Hat Services without using the rhc client.

2.5.1. Considerations for using the legacy client for registration
Link kopieren

The main reason to use the legacy client to register a RHEL system to Red Hat Services is to have more control over the features and the data collected from the system. With RHEL 10.0, the rhc client has a concept of “feature level” that allows it to control the level of information collected from the system. However, for RHEL 8.0 and RHEL 9.0, achieving a registration by using the rhc client enables all the features with no command-line options needed to make adjustments. Using only the subscription-manager or a combination of subscription-manager and insights-client remains a supported route.

To register a system running a version of RHEL 8.7 or earlier, or to manually control feature levels by using Red Hat Lightspeed, use the following two-step process:

  • Register to Red Hat Subscription Manager (RHSM) with the subscription-manager client.
  • Register the system with insights-client.

Prerequisites

Procedure

  1. To register a system running Red Hat Enterprise Linux version 7 or 8, use an activation key and your Organization ID to register with RHSM. 

    # subscription-manager register --activationkey=_activation_key_name_ --org=_organization_ID_
    Copy to Clipboard Toggle word wrap

  2. Enter the insights-client command to complete registration for the Red Hat Lightspeed service. 

    # insights-client --register
    Copy to Clipboard Toggle word wrap

2.5.3. Register and convert a CentOS Linux 7 system to a RHEL 7 system
Link kopieren

To convert a CentOS Linux 7 system to a RHEL, first register it with Red Hat to connect to Red Hat Lightspeed. After completing backups and other prerequisites, perform a pre-conversion analysis to identify risks for the conversion. You can then use the Red Hat Lightspeed conversion task for converting the system to a fully-supported RHEL 7 environment.

2.6. System remediation and automation with Red Hat Lightspeed
Link kopieren

To prepare your RHEL system to automatically run tasks and remediation plans, you must use both the rhc client and the insights-client. Together, these tools allow Red Hat Lightspeed to automatically generate and execute Ansible Playbooks to address identified issues. To enable your system with automated remediation, install and activate core components, complete system registration and enable remote management with the yggdrasil daemon. Your systems can directly use tasks and remediation playbooks from the Red Hat Lightspeed Automation Toolkit after registration.
