Install and configure controller node

This section describes how to install and configure the Block Storage service, code-named cinder, on the controller node. This service requires at least one additional storage node that provides volumes to instances.

Prerequisites

Before you install and configure the Block Storage service, you must create a database, service credentials, and API endpoints.

  1. To create the database, complete these steps:

    1. Use the database access client to connect to the database server as the root user:

      $ mysql -u root -p

    2. Create the cinder database:

      MariaDB [(none)]> CREATE DATABASE cinder;

    3. Grant proper access to the cinder database:

      MariaDB [(none)]> GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'localhost' \
  IDENTIFIED BY 'CINDER_DBPASS';
MariaDB [(none)]> GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'%' \
  IDENTIFIED BY 'CINDER_DBPASS';

      Replace CINDER_DBPASS with a suitable password.

    4. Exit the database access client.

  2. Source the admin credentials to gain access to admin-only CLI commands:

    $ . admin-openrc

  3. To create the service credentials, complete these steps:

    1. Create a cinder user:

       $ openstack user create --domain default --password-prompt cinder

User Password:
Repeat User Password:
+---------------------+----------------------------------+
| Field               | Value                            |
+---------------------+----------------------------------+
| domain_id           | default                          |
| enabled             | True                             |
| id                  | 9d7e33de3e1a498390353819bc7d245d |
| name                | cinder                           |
| options             | {}                               |
| password_expires_at | None                             |
+---------------------+----------------------------------+

    2. Add the admin role to the cinder user:

      $ openstack role add --project service --user cinder admin

    Note

    This command provides no output.

    1. Create the cinderv2 and cinderv3 service entities:

       $ openstack service create --name cinderv2 \
  --description "OpenStack Block Storage" volumev2

+-------------+----------------------------------+
| Field       | Value                            |
+-------------+----------------------------------+
| description | OpenStack Block Storage          |
| enabled     | True                             |
| id          | eb9fd245bdbc414695952e93f29fe3ac |
| name        | cinderv2                         |
| type        | volumev2                         |
+-------------+----------------------------------+

       $ openstack service create --name cinderv3 \
  --description "OpenStack Block Storage" volumev3

+-------------+----------------------------------+
| Field       | Value                            |
+-------------+----------------------------------+
| description | OpenStack Block Storage          |
| enabled     | True                             |
| id          | ab3bbbef780845a1a283490d281e7fda |
| name        | cinderv3                         |
| type        | volumev3                         |
+-------------+----------------------------------+

Note

The Block Storage services require two service entities.

  1. Create the Block Storage service API endpoints:

    $ openstack endpoint create --region RegionOne \
  volumev2 public http://controller:8776/v2/%\(project_id\)s

+--------------+------------------------------------------+
| Field        | Value                                    |

    Note

    The Block Storage services require endpoints for each service entity.

Install and configure components

  1. Install the packages:

    # zypper install openstack-cinder-api openstack-cinder-scheduler

  2. Edit the /etc/cinder/cinder.conf file and complete the following actions:

    1. In the [database] section, configure database access:

      [database]
# ...
connection = mysql+pymysql://cinder:CINDER_DBPASS@controller/cinder

      Replace CINDER_DBPASS with the password you chose for the Block Storage database.

    2. In the [DEFAULT] section, configure RabbitMQ message queue access:

      [DEFAULT]
# ...
transport_url = rabbit://openstack:RABBIT_PASS@controller

      Replace RABBIT_PASS with the password you chose for the openstack account in RabbitMQ.

  1. In the [DEFAULT] and [keystone_authtoken] sections, configure Identity service access:

      [DEFAULT]
  # ...
  auth_strategy = keystone

  [keystone_authtoken]
  # ...
  auth_uri = http://controller:5000
  auth_url = http://controller:35357
  memcached_servers = controller:11211
  auth_type = password
  project_domain_name = default
  user_domain_name = default
  project_name = service
  username = cinder
  password = CINDER_PASS

Replace ``CINDER_PASS`` with the password you chose for
the ``cinder`` user in the Identity service.

.. note::

   Comment out or remove any other options in the
   ``[keystone_authtoken]`` section.

  1. In the [DEFAULT] section, configure the my_ip option to use the management interface IP address of the controller node:

    [DEFAULT]
# ...
my_ip = 10.0.0.11

  1. In the [oslo_concurrency] section, configure the lock path:

    [oslo_concurrency]
# ...
lock_path = /var/lib/cinder/tmp

Configure Compute to use Block Storage

  1. Edit the /etc/nova/nova.conf file and add the following to it:

    [cinder]
os_region_name = RegionOne

Finalize installation

  1. Restart the Compute API service:

    # systemctl restart openstack-nova-api.service

  2. Start the Block Storage services and configure them to start when the system boots:

    # systemctl enable openstack-cinder-api.service openstack-cinder-scheduler.service
# systemctl start openstack-cinder-api.service openstack-cinder-scheduler.service
