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:

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

     $ mysql -u root -p

   • Create the cinder database:

     CREATE DATABASE cinder;

   • Grant proper access to the cinder database:

     GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'localhost' \
       IDENTIFIED BY 'CINDER_DBPASS';
     GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'%' \
       IDENTIFIED BY 'CINDER_DBPASS';

     Replace CINDER_DBPASS with a suitable password.

   • Exit the database access client.

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

   $ source admin-openrc.sh

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

   • 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        | bb279f8ffc444637af38811a5e1f0562 |
     | name      | cinder                           |
     +-----------+----------------------------------+

   • Add the admin role to the cinder user:

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

     Note

     This command provides no output.

   • Create the cinderv2 service entity:

     $ openstack service create --name cinderv2 \
       --description "OpenStack Block Storage" volumev2
     +-------------+----------------------------------+
     | Field       | Value                            |
     +-------------+----------------------------------+
     | description | OpenStack Block Storage          |
     | enabled     | True                             |
     | id          | eb9fd245bdbc414695952e93f29fe3ac |
     | name        | cinderv2                         |
     | type        | volumev2                         |
     +-------------+----------------------------------+

4. Create the Block Storage service API endpoints:

   $ openstack endpoint create --region RegionOne \
     volumev2 public http://controller:8776/v2/%\(tenant_id\)s
   +--------------+-----------------------------------------+
   | Field        | Value                                   |
   +--------------+-----------------------------------------+
   | enabled      | True                                    |
   | id           | 513e73819e14460fb904163f41ef3759        |
   | interface    | public                                  |
   | region       | RegionOne                               |
   | region_id    | RegionOne                               |
   | service_id   | eb9fd245bdbc414695952e93f29fe3ac        |
   | service_name | cinderv2                                |
   | service_type | volumev2                                |
   | url          | http://controller:8776/v2/%(tenant_id)s |
   +--------------+-----------------------------------------+
   
   $ openstack endpoint create --region RegionOne \
     volumev2 internal http://controller:8776/v2/%\(tenant_id\)s
   +--------------+-----------------------------------------+
   | Field        | Value                                   |
   +--------------+-----------------------------------------+
   | enabled      | True                                    |

Install and configure components

obs

1. Install the packages:

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

rdo

1. Install the packages:

   # yum install openstack-cinder python-cinderclient python-oslo-db

ubuntu

1. Install the packages:

   # apt-get install cinder-api cinder-scheduler python-cinderclient

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

   • 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.

   • In the [DEFAULT] and [oslo_messaging_rabbit] sections, configure RabbitMQ message queue access:

     [DEFAULT]
     ...
     rpc_backend = rabbit
     
     [oslo_messaging_rabbit]
     ...
     rabbit_host = controller
     rabbit_userid = openstack
     rabbit_password = RABBIT_PASS

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

   • 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
     auth_plugin = password
     project_domain_id = default
     user_domain_id = 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.

   • 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

   • In the [oslo_concurrency] section, configure the lock path:

     [oslo_concurrency]
     ...
     lock_path = /var/lock/cinder

   • (Optional) To assist with troubleshooting, enable verbose logging in the [DEFAULT] section:

     [DEFAULT]
     ...
     verbose = True

3. Populate the Block Storage database:

   # su -s /bin/sh -c "cinder-manage db sync" cinder

Configure Compute to use Block Storage

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

  [cinder]
  os_region_name = RegionOne

Finalize installation

obs or rdo

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

ubuntu

1. Restart the Compute API service:

   # service nova-api restart

2. Restart the Block Storage services:

   # service cinder-scheduler restart
   # service cinder-api restart

3. By default, the Ubuntu packages create an SQLite database.

   Because this configuration uses an SQL database server, you can remove the SQLite database file:

   # rm -f /var/lib/cinder/cinder.sqlite
