Variations of this question have been asked, but is there an installation guide for installing the Cinder service on a different node than the controller node?

Thank you in advance....

You will follow the same guides. Just install the service on another node and then setup the keystone endpoints on the controller to point to the new nodes IP : Port.

Most of the guides do not document separation of services other than Networking. I would look through your current guides, look for anything referencing the Cinder API in configuration files for Nova/Glance/Services, then verify that the endpoint matches the IP address of the other node. Verify that Keystone has the correct endpoints as well.

Steps would include:

Verify connectivity between the new node and the current controller.
Install Cinder services on the new node.
Configure Cinder services, using the original controller IP/Hostname for all keystone auth info.
Verify Cinder services on the new node.
Verify connectivity from the controller to the new node IP + port. Telnet test works.
Configure Keystone endpoint for cinder, point it at the new node.

For clarification and for others trying the same thing, you need to make a change with the database connection?

database connection mysql://cinder:CINDER_DBPASS@controller/cinder

Instead of controller it should be localhost?

If you are editing the Glance Configuration files then it will be:


The IP and port that MySQL is listening on. This will probably be the main controller. If you want to use hostnames then you need DNS or an entry in /etc/hosts.

The database (steps 2-4 on the install Cinder guide) should be created on the controller not the node with Cinder?

Thank you....

Not sure which guide you are using. If you are adding a DB to MySQL then that needs to be setup on the main controller. All you are setting up on the cinder node is the cinder services as in installing + configuring cinder.

This guide: . So /etc/cinder/cinder.conf should be configured to point to DB on the main controller?

Also, you mentioned Glance config files above??
