Troubleshooting Renaming SUSE Manager Server

If you change the hostname of the SUSE Manager Server locally, your SUSE Manager installation will cease to work properly. This is because the changes have not been made in the database, which prevents the changes from propagating out your clients and any proxies.

If you need to change the hostname of the SUSE Manager Server, you can do so using the spacewalk-hostname-rename script. This script updates the settings in the PostgreSQL database and the internal structures of SUSE Manager.

The spacewalk-hostname-rename script is part of the spacewalk-utils package.

The only mandatory parameter for the script is the newly configured IP address of the SUSE Manager Server.

Procedure: Renaming SUSE Manager Server
  1. Change the network settings of the server on the system level locally and remotely at the DNS server. You will also need to provide configuration settings for reverse name resolution. Changing network settings is done in the same way as with renaming any other system.

  2. Reboot the SUSE Manager Server to use the new network configuration and to ensure the hostname has changed.

  3. Remove the old rhn-org-httpd-ssl-key-pair package:

    zypper rm  package rhn-org-httpd-ssl-key-pair
  4. Run the script spacewalk-hostname-rename script with the public IP address of the server. If the server is not using the new hostname, the script will fail.

  5. Re-configure your clients to make your environment aware of the new hostname and IP address.

    In the Salt minion configuration file /etc/salt/minion, you must make sure to specify the name of the new Salt master (SUSE Manager Server):

    master: <new_hostname>

    Traditional clients have the /etc/sysconfig/rhn/up2date configuration file that must be changed. With a re-activation key you can re-register traditional clients (if there are any). For more information, see client-configuration:registration-cli.adoc.

  6. OPTIONAL: If you use PXE boot through a SUSE Manager Proxy, you must check the configuration settings of the proxy. On the proxy, run the setup script and enter the requested information. For more information, see installation:proxy-setup.adoc.
