Chapter 13. Renaming Satellite Server or Capsule Server

Procedure

1. On Satellite Server, run the satellite-change-hostname script, and provide the new host name. Choose one of the following methods:

   • If your Satellite Server is installed with the default self-signed SSL certificates:

     # satellite-change-hostname new-satellite \
     --username My_Username \
     --password My_Password

   • If your Satellite Server is installed with custom SSL certificates:

     # satellite-change-hostname new-satellite \
     --username My_Username \
     --password My_Password \
     --custom-cert "/root/ownca/test.com/test.com.crt" \
     --custom-key "/root/ownca/test.com/test.com.key"

2. 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 in a connected network environment.
3. Reregister all hosts and Capsule Servers that are registered to Satellite Server. For more information, see Registering Hosts in Managing hosts.

4. On all Capsule Servers, run the Satellite installation script to update references to the new host name:

   # satellite-installer \
   --foreman-proxy-foreman-base-url https://new-satellite.example.com \
   --foreman-proxy-trusted-hosts new-satellite.example.com

5. On Satellite Server, list all Capsule Servers:

   # hammer capsule list

6. On Satellite Server, synchronize content for each Capsule Server:

   # hammer capsule content synchronize \
   --id My_capsule_ID

7. If you use the virt-who agent, update the virt-who configuration files with the new host name. For more information, see Modifying a virt-who Configuration in Configuring virtual machine subscriptions.
8. If you use external authentication, reconfigure Satellite Server for external authentication after you run the satellite-change-hostname script. For more information, see Configuring External Authentication in Installing Satellite Server in a connected network environment.

Procedure

1. On your Satellite Server, generate a new certificates archive file for your Capsule Server.

   • If you are using the default SSL certificate, regenerate the default SSL certificates:

     # capsule-certs-generate \
     --certs-tar /root/new-capsule.example.com-certs.tar \
     --foreman-proxy-fqdn new-capsule.example.com

     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 your Capsule Server. For more information, see Configuring Capsule Server with a Custom SSL Certificate in Installing Capsule Server.

2. On your Satellite Server, copy the certificates archive file to your Capsule Server. For example, to copy the archive file to the root user’s home directory:

   # scp /root/new-capsule.example.com-certs.tar root@capsule.example.com:

3. On your Capsule Server, run the satellite-change-hostname script and provide the host’s new name, Satellite credentials, and certificates archive file name.

   # satellite-change-hostname new-capsule.example.com \
   --certs-tar /root/new-capsule.example.com-certs.tar \
   --password My_Password \
   --username My_Username

   Ensure that you enter the full path to the .tar file.

4. If you have created a custom certificate for your Capsule Server, deploy the certificate to your Capsule Server by entering the satellite-installer command that the capsule-certs-generate command returned in a previous step. For more information, see Deploying a Custom SSL Certificate to Capsule Server in Installing Capsule Server.

5. On all hosts registered to your Capsule Server, enter the following commands to reinstall the bootstrap RPM, reregister clients, and refresh their subscriptions.

   You can use the remote execution feature to perform this step. For more information, see Configuring and Setting up Remote Jobs in Managing hosts.

   # dnf remove katello-ca-consumer*
   
   # dnf install http://new-capsule.example.com/pub/katello-ca-consumer-latest.noarch.rpm
   
   # subscription-manager register \
   --environment="My_Lifecycle_Environment" \
   --force \
   --org="My_Organization"
   
   # subscription-manager refresh

6. Update the Capsule host name in the Satellite web UI.

   1. In the Satellite web UI, navigate to Infrastructure > Capsules.
   2. Locate Capsule Server in the list, and click Edit.
   3. Edit the Name and URL fields to match Capsule Server’s new host name, then click Submit.
   4. On your DNS server, add a record for the new hostname of your Capsule Server, and delete the record of the previous host name.
