6.5. Enabling the Certificate System Repository

Before you can install and update Certificate System using the yum utility, you must enable the corresponding repository:
  1. Attach the Red Hat subscriptions to the system:
    Skip this step, if your system is already registered or has a Certificate Server subscription attached.
    1. Register the system to the Red Hat subscription management service:
      # subscription-manager register --auto-attach
      Username: admin@example.com
      Password:
      The system has been registered with id: 566629db-a4ec-43e1-aa02-9cbaa6177c3f
      
      Installed Product Current Status:
      Product Name:           Red Hat Enterprise Linux Server
      Status:                 Subscribed
      Use the --auto-attach option to automatically apply a subscription for the operating system.
    2. List the available subscriptions and note the pool ID providing the Red Hat Certificate System. For example:
      # subscription-manager list --available --all
      ...
      Subscription Name:   Red Hat Enterprise Linux Developer Suite
      Provides:            ...
                           Red Hat Certificate System
                           ...
      Pool ID:             7aba89677a6a38fc0bba7dac673f7993
      Available:           1
      ...
      In case you have a lot of subscriptions, the output of the command can be very long. You can optionally redirect the output to a file:
      # subscription-manager list --available --all > /root/subscriptions.txt
    3. Attach the Certificate System subscription to the system using the pool ID from the previous step:
      # subscription-manager attach --pool=7aba89677a6a38fc0bba7dac673f7993
      Successfully attached a subscription for: Red Hat Enterprise Linux Developer Suite
  2. Enable the Certificate Server repository:
    # subscription-manager repos --enable=rhel-7-server-rhcmsys-9-rpms
    Repository 'rhel-7-server-rhcmsys-9-rpms' is enabled for this system.
Installing the required packages is described in the Chapter 7, Installing and Configuring Certificate System chapter.
