Chapter 2. Start, stop, and restart automation controller
Automation controller ships with an administrator utility script, automation-controller-service. The script can start, stop, and restart all automation controller services running on the current single automation controller node. The script includes the message queue components and the database if it is an integrated installation.
External databases must be explicitly managed by the administrator. You can find the services script in /usr/bin/automation-controller-service, which can be invoked with the following command:
root@localhost:~$ automation-controller-service restart
In clustered installs, the automation-controller-service restart does not include PostgreSQL as part of the services that are restarted. This is because it exists external to automation controller, and PostgreSQL does not always need to be restarted. Use systemctl restart automation-controller to restart services on clustered environments instead.
You must also restart each cluster node for certain changes to persist as opposed to a single node for a localhost install.
For more information on clustered environments, see the Clustering section.
You can also invoke the services script using distribution-specific service management commands. Distribution packages often provide a similar script, sometimes as an init script, to manage services. For more information, see your distribution-specific service management system.
When running automation controller in a container, do not use the automation-controller-service script. Restart the pod using the container environment instead.
