Chapter 18. Migrate to a new load balancer, or change the name of an existing load balancer

Procedure

   # systemctl stop pulp_\*

2. Remove the content delivery server (CDS) certificate files from the Red Hat Update Appliance (RHUA).

   # rm -f /etc/puppet/rhui-secrets/cds-cert.*

3. Run rhui-manager with the new load balancer host name, for example:

   # rhui-installer --cds-lb-hostname=hap02.example.com

   Note

   Use any other necessary arguments if you do not want their initial or default values as indicated by the answers file.

4. Add the new load balancer to the RHUI environment, either in the interactive mode (rhui-manager - l - a - …​) or in the CLI. For the CLI, use the following example:

    # rhui cds reinstall cds01.example.com

6. Create an updated client configuration RPM. This can be done in the interactive mode (rhui-manager - e - c - …​`) or in the CLI. For the CLI, use the following example:

   # rhui-manager client rpm --private_key /root/rhui.key --entitlement_cert /root/rhui.crt --rpm_version 2.1 --rpm_name rhui-repos --dir /root/
