Managing Glance Services

Following are the primary services which should be running on the openstack server :

  • glance-registry
  • glance-api

glance-registry

Check the status of the service

root@ubuntudevstack02022017-091801:~# glance-control registry status
glance-registry is stopped
root@ubuntudevstack02022017-091801:~#

Start the service

root@ubuntudevstack02022017-091801:~# glance-control registry status
glance-registry is stopped
root@ubuntudevstack02022017-091801:~#

In the same way you can also stop the service.

glance-api

Check the status of the service

root@ubuntudevstack02022017-091801:~# glance-control api status
glance-api is stopped
root@ubuntudevstack02022017-091801:~#

Start the service

root@ubuntudevstack02022017-091801:~# glance-control api start
Starting glance-api
root@ubuntudevstack02022017-091801:~# glance-control api status
glance-api (pid 22803) is running...
root@ubuntudevstack02022017-091801:~#

In the same way you can also stop the service.

We can also validate the running processes
