3. Create the database for Gnocchi's indexer:
* Use the database access client to connect to the database
server as the ``root`` user:
.. code-block:: console
$ mysql -u root -p
* Create the ``gnocchi`` database:
.. code-block:: console
CREATE DATABASE gnocchi;
* Grant proper access to the ``gnocchi`` database:
.. code-block:: console
GRANT ALL PRIVILEGES ON gnocchi.* TO 'gnocchi'@'localhost' \
IDENTIFIED BY 'GNOCCHI_DBPASS';
GRANT ALL PRIVILEGES ON gnocchi.* TO 'gnocchi'@'%' \
IDENTIFIED BY 'GNOCCHI_DBPASS';
Replace ``GNOCCHI_DBPASS`` with a suitable password.
* Exit the database access client.
4. Edit the ``/etc/gnocchi/gnocchi.conf`` file and add Keystone options:
* In the ``[api]`` section, configure gnocchi to use keystone:
.. code-block:: ini
[api]
auth_mode = keystone
port = 8041
uwsgi_mode = http-socket
* In the ``[keystone_authtoken]`` section, configure keystone
authentication:
.. code-block:: ini
[keystone_authtoken]
...
auth_type = password
auth_url = http://controller:5000/v3
project_domain_name = Default
user_domain_name = Default
project_name = service
username = gnocchi
password = GNOCCHI_PASS
interface = internalURL
region_name = RegionOne
Replace ``GNOCCHI_PASS`` with the password you chose for
the ``gnocchi`` user in the Identity service.
* In the ``[indexer]`` section, configure database access:
.. code-block:: ini
[indexer]
url = mysql+pymysql://gnocchi:GNOCCHI_DBPASS@controller/gnocchi
Replace ``GNOCCHI_DBPASS`` with the password you chose for Gnocchi's
indexer database.
* In the ``[storage]`` section, configure location to store metric data.
In this case, we will store it to the local file system. See Gnocchi
documenation for a list of more durable and performant drivers:
.. code-block:: ini
[storage]
# coordination_url is not required but specifying one will improve
# performance with better workload division across workers.
coordination_url = redis://controller:6379
file_basepath = /var/lib/gnocchi
driver = file
5. Initialize Gnocchi:
.. code-block:: console
gnocchi-upgrade
