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.

obs or rdo or ubuntu

Prerequisites

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

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.
Source the admin credentials to gain access to admin-only CLI commands:
```
$ . admin-openrc
```

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 | e0353a670a9e496da891347c589539e9 |
| 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 cinder and cinderv2 service entities:

$ openstack service create --name cinder \
  --description "OpenStack Block Storage" volume
+-------------+----------------------------------+
| Field       | Value                            |
+-------------+----------------------------------+
| description | OpenStack Block Storage          |
| enabled     | True                             |
| id          | ab3bbbef780845a1a283490d281e7fda |
| name        | cinder                           |
| type        | volume                           |
+-------------+----------------------------------+

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

Note

The Block Storage services require two service entities.

Create the Block Storage service API endpoints:

$ openstack endpoint create --region RegionOne \

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

Note

The Block Storage services require endpoints for each service entity.

Install and configure components

obs

Install the packages:

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

rdo

Install the packages:
```
# yum install openstack-cinder
```

ubuntu or debian

```
# apt-get install cinder-api cinder-scheduler
```
debian

Respond to prompts for database management <debconf/debconf-dbconfig-common>, Identity service credentials <debconf/debconf-keystone-authtoken>, service endpoint registration <debconf/debconf-api-endpoints>, and message broker credentials <debconf/debconf-rabbitmq>.

Edit the /etc/cinder/cinder.conf file and complete the following actions:
obs or rdo or ubuntu
- In the [database] section, configure database access:
```
[database]
...
connection = mysql+pymysql://cinder:CINDER_DBPASS@controller/cinder
```

```
[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
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.
- 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
```
obs or rdo or ubuntu
- In the [oslo_concurrency] section, configure the lock path:
```
[oslo_concurrency]
...
lock_path = /var/lib/cinder/tmp
```

rdo or ubuntu

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

Restart the Compute API service:

# systemctl restart openstack-nova-api.service

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
