Hello,

I'm trying to install glance on Openstack Stein on Ubuntu 18.04. I have managed to populate populate the image service database with "glance-manage db_sync" and this is the result in my database:

| Tables_in_glance                 |
+----------------------------------+
| alembic_version                  |
| image_locations                  |
| image_members                    |
| image_properties                 |
| image_tags                       |
| images                           |
| metadef_namespace_resource_types |
| metadef_namespaces               |
| metadef_objects                  |
| metadef_properties               |
| metadef_resource_types           |
| metadef_tags                     |
| migrate_version                  |
| task_info                        |
| tasks                            |
+----------------------------------+

I have configured the glance-api,conf and glance-registry.conf and when i tried to list the image or register the image with:

openstack image create "cirros" --file cirros-0.4.0-x86_64-disk.img --disk-format qcow2 --container-format bare --public

then got the error:

oslo_db.exception.DBConnectionError: (pymysql.err.OperationalError) (2003, "Can't connect to MySQL server on 'stack-controller' ([Errno 111] ECONNREFUSED)") (Background on this error at: http://sqlalche.me/e/e3q8)

stack-controller is my localhost hostname and i can reach it using domain or IP. and on my environment (ubuntu 18.04 - openstack stein) somehow i cant do the command:

service glance-registry restart  ##=> it said no service name it

but able to use command

service glance-api restart

please can anyone help, really need suggestion how to solve this

thanks
