14.2. Configuring a Host for Registration

Red Hat Enterprise Linux hosts register to the Red Hat Network (RHN) by default. You must update each host configuration so that they register to and update from the correct Red Hat Satellite Server.

Prerequisites

Address the following requirements before proceeding:
  • Hosts must be using the following Red Hat Enterprise Linux Version:
    • 5.8 or later (5.7 or later on s390x)
    • 6.4 or later
    • 7.0 or later
  • All architectures of Red Hat Enterprise Linux are supported (i386, x86_64, s390x, ppc_64)
  • On the Red Hat Satellite Server, ensure that the date and time are correct and synchronized with the client.
  • On each client system, address the following requirements:
    • Ensure that the date and time are correct and synchronized with the server.
    • Enable ntpd or a similar time synchronization tool in all virtual environments:
      For Red Hat Enterprise Linux 6:
      # chkconfig ntpd on; service ntpd start
      For Red Hat Enterprise Linux 7:
      # systemctl start chronyd; systemctl enable chronyd
The following procedure shows how to automatically configure your client system to register to Red Hat Satellite.

Procedure 14.2. To Automatically Configure a Host:

  1. Take note of the Red Hat Satellite's fully qualified domain name (FQDN), for example satellite.example.com.
  2. Open a terminal console and log in as root.
  3. Download and install a copy of the CA Certificate for the host from the Red Hat Satellite FQDN:
    # rpm -Uvh http://satellite.example.com/pub/katello-ca-consumer-latest.noarch.rpm
    

    Note

    katello-ca-consumer-hostname-1.0-1.noarch.rpm is an additional katello-ca-consumer rpm available that contains the server's hostname. The katello-ca-consumer-latest.noarch.rpm rpm will always reflect the most updated version. Both serve the same purpose.
