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.
|
|
|
|
#. To create the database, complete these steps:
|
|
|
|
|
|
|
|
* Use the database access client to connect to the database
|
|
server as the ``root`` user:
|
|
|
|
.. code-block:: console
|
|
|
|
$ mysql -u root -p
|
|
|
|
.. end
|
|
|
|
|
|
* Create the ``cinder`` database:
|
|
|
|
.. code-block:: console
|
|
|
|
MariaDB [(none)]> CREATE DATABASE cinder;
|
|
|
|
.. end
|
|
|
|
* Grant proper access to the ``cinder`` database:
|
|
|
|
.. code-block:: console
|
|
|
|
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';
|
|
|
|
.. end
|
|
|
|
Replace ``CINDER_DBPASS`` with a suitable password.
|
|
|
|
* Exit the database access client.
|
|
|
|
#. Source the ``admin`` credentials to gain access to admin-only
|
|
CLI commands:
|
|
|
|
.. code-block:: console
|
|
|
|
$ . admin-openrc
|
|
|
|
.. end
|
|
|
|
#. To create the service credentials, complete these steps:
|
|
|
|
* Create a ``cinder`` user:
|
|
|
|
.. code-block:: console
|
|
|
|
$ 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 |
|
|
+---------------------+----------------------------------+
|
|
|
|
.. end
|
|
|
|
* Add the ``admin`` role to the ``cinder`` user:
|
|
|
|
.. code-block:: console
|
|
|
|
$ openstack role add --project service --user cinder admin
|
|
|
|
.. end
|
|
|
|
.. note::
|
|
|
|
This command provides no output.
|
|
|
|
* Create the ``cinderv2`` and ``cinderv3`` service entities:
|
|
|
|
.. code-block:: console
|
|
|
|
$ openstack service create --name cinderv2 \
|
|
--description "OpenStack Block Storage" volumev2
|
|
|

|

| Field | Value |

|
| enabled | True |
|
|
| id | eb9fd245bdbc414695952e93f29fe3ac |
|
|
| name | cinderv2 |
|
|
| type | volumev2 |
|
|
+-------------+----------------------------------+
|
|
|
|
.. end
|
|
|
|
.. code-block:: console
|
|
|
|
$ openstack service create --name cinderv3 \
|
|
--description "OpenStack Block Storage" volumev3
|
|
|
|
+-------------+----------------------------------+
|
|
| Field | Value |
|

|
|

|
|
| name | cinderv3 |
|
|
| type | volumev3 |
|
|
+-------------+----------------------------------+
|
|
|
|
.. end
|
|
|
|
.. note::
|
|
|
|
The Block Storage services require two service entities.
|
|
|
|
#. Create the Block Storage service API endpoints:
|
|
|
|

|
.. end
|
|
|
|
.. note::
|
|
|
|
The Block Storage services require endpoints for each service
|
|
entity.
|
|
|
|
Install and configure components
|
|
--------------------------------
|
|
|
|
|
|
|
|
|
|
#. Install the packages:
|
|
|
|
.. code-block:: console
|
|
|
|
# apt install cinder-api cinder-scheduler
|
|
|
|
.. end
|
|
|
|
|
|
2. Edit the ``/etc/cinder/cinder.conf`` file and complete the
|
|
following actions:
|
|
|
|
* In the ``[database]`` section, configure database access:
|
|
|
|
.. path /etc/cinder/cinder.conf
|
|
.. code-block:: ini
|
|
|
|
[database]
|
|
# ...
|
|
connection = mysql+pymysql://cinder:CINDER_DBPASS@controller/cinder
|
|
|
|
.. end
|
|
|
|
Replace ``CINDER_DBPASS`` with the password you chose for the
|
|
Block Storage database.
|
|
|
|
* In the ``[DEFAULT]`` section, configure ``RabbitMQ``
|
|
message queue access:
|
|
|
|
.. path /etc/cinder/cinder.conf
|
|
.. code-block:: ini
|
|
|
|
[DEFAULT]
|
|
# ...
|
|
transport_url = rabbit://openstack:RABBIT_PASS@controller
|
|
|
|
.. end
|
|
|
|
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:
|
|
|
|
.. path /etc/cinder/cinder.conf
|
|
.. code-block:: ini
|
|
|
|
[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
|
|
|
|
.. end
|
|
|
|
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:
|
|
|
|
.. path /etc/cinder/cinder.conf
|
|
.. code-block:: ini
|
|
|
|
[DEFAULT]
|
|
# ...
|
|
my_ip = 10.0.0.11
|
|
|
|
.. end
|
|
|
|
|
|
|
|
3. Populate the Block Storage database:
|
|
|
|
.. code-block:: console
|
|
|
|
# su -s /bin/sh -c "cinder-manage db sync" cinder
|
|
|
|
.. end
|
|
|
|
.. note::
|
|
|
|
Ignore any deprecation messages in this output.
|
|
|
|
|
|
Configure Compute to use Block Storage
|
|
--------------------------------------
|
|
|
|
* Edit the ``/etc/nova/nova.conf`` file and add the following
|
|
to it:
|
|
|
|
.. path /etc/nova/nova.conf
|
|
.. code-block:: ini
|
|
|
|
[cinder]
|
|
os_region_name = RegionOne
|
|
|
|
.. end
|
|
|
|
Finalize installation
|
|
---------------------
|
|
|
|
|
|
|
|
#. Restart the Compute API service:
|
|
|
|
.. code-block:: console
|
|
|
|
# service nova-api restart
|
|
|
|
.. end
|
|
|
|
#. Restart the Block Storage services:
|
|
|
|
.. code-block:: console
|
|
|
|
# service cinder-scheduler restart
|
|
# service apache2 restart
|
|
|
|
.. end
|
|
|
