Chapter 8. Registering Hosts for Conversion

You have to register your hosts to Satellite before you can convert them to Red Hat Enterprise Linux. You have Satellite generate a registration command that you then execute on each host.

You can run the registration command in bulk by using a configuration management tool, such as Ansible or Puppet, to register a larger amount of hosts.

Prerequisites

  • You have configured Satellite for conversions. For more information, see Chapter 7, Configuring Satellite for Conversions.
  • Ensure that a time-synchronization tool is installed and enabled on your hosts. Satellite and all hosts must be synchronized with the same NTP server.
  • Ensure that the SSL CA file of Satellite is distributed onto your hosts. You can find the location of the SSL CA file by navigating to Administer > Settings > Authentication and locating the value of the SSL CA file setting.

Procedure

  1. Optional: Enable reporting to Red Hat Insights. The conversions toolkit disables new hosts from reporting to Insights by setting the global parameter host_registration_insights to false. For more information, see Global Parameters for Registration in Managing Hosts.
  2. In to the Satellite web UI, navigate to Hosts > Register Host.
  3. In the Host group field, select the CentOS 7 converting host group.
  4. In the Activation Keys field, ensure that the convert2rhel_centos7 activation key is present.
  5. Click Generate.
  6. Copy the generated registration command.
  7. Log in to a host by using SSH and run the registration command as root.

Verification

  • In the Satellite web UI, navigate to Hosts > All Hosts. You can find all hosts that you have registered to Satellite.
