Chapter 10. Renaming Satellite Server or Capsule Server To rename Satellite Server or Capsule Server, you must use the satellite-change-hostname script. If you rename Satellite Server, you must reregister all Satellite clients and configure each Capsule Server to point them to the new Satellite host name. If you use custom SSL certificates, you must regenerate them with the new host name. If you use virt-who, you must update the virt-who configuration files with the new host name. If you rename Capsule Server, you must reregister all Capsule clients and update the Capsule host name in the Satellite web UI. If you use custom SSL certificates, you must regenerate them with the new host name. Warning The renaming process shuts down all Satellite Server services on the host being renamed. When the renaming is complete, all services are restarted. 10.1. Renaming Satellite Server The host name of Satellite Server is used by Satellite Server components, all Capsule Servers, and hosts registered to it for communication. This procedure ensures that you update all references to the new host name. If you use external authentication, you must reconfigure Satellite Server for external authentication after you run the satellite-change-hostname script. The satellite-change-hostname script breaks external authentication for Satellite Server. For more information about configuring external authentication, see Chapter 14, Configuring External Authentication . If you use virt-who, you must update the virt-who configuration files with the new host name after you run the satellite-change-hostname script. For more information, see Modifying a virt-who Configuration in Configuring Virtual Machine Subscriptions in Red Hat Satellite . Prerequisites Both the hostname and hostname -f commands must return the FQDN of Satellite Server or the satellite-change-hostname script will fail to complete. If the hostname command returns the shortname of Satellite Server instead of the FQDN, use hostnamectl set-hostname old_fqdn to set the old FQDN correctly before attempting to use the satellite-change-hostname script. Perform a backup of Satellite Server before changing a host name. If the renaming process is not successful, you must restore it from a backup. For more information, see Chapter 8, Backing Up Satellite Server and Capsule Server . Optional: If Satellite Server has a custom SSL certificate installed, a new certificate must be obtained for the host's new name. For more information, see Configuring Satellite Server with a Custom SSL Certificate in Installing Satellite Server from a Connected Network . Procedure On Satellite Server, choose the appropriate method to run the satellite-change-hostname script, providing the new host name and Satellite credentials: If your Satellite Server is installed with default self-signed SSL certificates, enter the following command: If your Satellite Server is installed with custom SSL certificates: Optional: If you have created a custom SSL certificate for the new Satellite Server host name, run the Satellite installation script to install the certificate. For more information about installing a custom SSL certificate, see Deploying a Custom SSL Certificate to Satellite Server in Installing Satellite Server from a Connected Network . Reregister all Satellite hosts. For more information, see Registering Hosts in Managing Hosts . On all Capsule Servers, run the Satellite installation script to update references to the new host name: On Satellite Server, list all Capsule Servers: On Satellite Server, synchronize content for each Capsule Server: 10.2. Renaming Capsule Server The host name of Capsule Server is referenced by Satellite Server components, and all hosts registered to it. This procedure ensures that you update all references to the new host name. Note Both the hostname and hostname -f commands must return the FQDN of Capsule Server or the satellite-change-hostname script will fail to complete. If the hostname command returns the shortname of Capsule Server instead of the FQDN, use hostnamectl set-hostname old_fqdn to set the old FQDN correctly before attempting to use the satellite-change-hostname script. Prerequisites Backup Capsule Server. The satellite-change-hostname script makes irreversible changes to Capsule Server. If the renaming process is not successful, you must restore it from a backup. Perform a backup before changing a host name. For more information, see Chapter 8, Backing Up Satellite Server and Capsule Server . Procedure On Satellite Server, generate a new certificates archive file for Capsule Server. If you are using the default SSL certificate, enter the following command: Ensure that you enter the full path to the .tar file. If you are using a custom SSL certificate, create a new SSL certificate for Capsule Server. For more information, see Configuring Capsule Server with a Custom SSL Certificate in Installing Capsule Server . On Satellite Server, copy the certificates archive file to Capsule Server, providing the root user's password when prompted. In this example the archive file is copied to the root user's home directory, but you may prefer to copy it elsewhere. On Capsule Server, run the satellite-change-hostname script and provide the host's new name, Satellite credentials, and certificates archive filename. Ensure that you enter the full path to the .tar file. Optional: If you have created a custom certificate for Capsule Server, on Capsule Server, to deploy the certificate, enter the satellite-installer command that the capsule-certs-generate command returns. For more information, see Deploying a Custom SSL Certificate to Capsule Server in Installing Capsule Server . On all Capsule clients, enter the following commands to reinstall the bootstrap RPM, reregister clients, and refresh their subscriptions. You can use remote execution feature to perform this step. For more information, see Configuring and Setting up Remote Jobs in the Managing Hosts Guide . In the Satellite web UI, navigate to Infrastructure > Capsules . Locate Capsule Server in the list, and click Edit to the right of it. Edit the Name and URL fields to match Capsule Server's new host name, then click Submit . On your DNS server, add a record for Capsule Server's new host name, and delete the record for the host name.
