IBM Cloud Orchestrator, Version 2.5

Stopping all the OpenStack services except Keystone

To ensure that there are no ongoing activities while your OpenStack installation is configured, you must stop the OpenStack services. Only Keystone and all middleware services must still be running as Keystone is accessed during the reconfiguration process.

You must stop the services on all the OpenStack servers only. Keystone service must still be running.

For information about managing services in IBM Cloud Manager with OpenStack, see Managing IBM Cloud Manager with OpenStack services.

You can then individually stop all the services by logging on to the servers and running the following command:

systemctl stop <service>

In IBM Cloud Manager with OpenStack, the OpenStack services are all the services that begin with neutron-, openstack-, or httpd, which is the Horizon service.

IBM® Cloud Orchestrator provides a sample script named control_services.sh to easily stop the services for IBM Cloud Manager with OpenStack. Review the script, adapt it to your environment if needed, and run the following command:

sh ./control_services.sh -o stop

Note: This command stops all the services on all the nodes.

You must run the command on all the IBM Cloud Manager with OpenStack servers.
