Checking the Status of Major OpenStack Service Components
After the deployment, you need to check the status of major service components on the controller node to ensure that OpenStack is running properly.
- Import environment variables.
source ~/.admin-openrc
- Check the Memcached service status.
systemctl status memcached.service
If active (running) is returned, the Memcached service is running properly. If the Memcached service status is abnormal, restart the service.
- Check the status of Nova services.
openstack compute service list
In the command output, if Status of each service is enabled and State is up, Nova services are running properly. If the status of Nova services is abnormal, restart the services.
- Check the status of Cinder services.
openstack volume service list
In the command output, if Status of each service is enabled and State is up, Cinder services are running properly. If the status of Cinder services is abnormal, restart the services.
- Check the status of Neutron services.
openstack network agent list
In the command output, if Alive of each service is :-) and State is UP, Neutron services are running properly. If the status of Neutron services is abnormal, restart the services.
