.. _trove-install:
Install and configure
~~~~~~~~~~~~~~~~~~~~~
This section describes how to install and configure the
Database service, code-named trove, on the controller node.
This section assumes that you already have a working OpenStack
environment with at least the following components installed:
Compute, Image Service, Identity.
* If you want to do backup and restore, you also need Object Storage.
* If you want to provision datastores on block-storage volumes, you also
need Block Storage.
.. only:: obs or rdo or ubuntu
Prerequisites
-------------
Before you install and configure the Database 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
* Create the ``trove`` database:
.. code-block:: console
CREATE DATABASE trove;
* Grant proper access to the ``trove`` database:
.. code-block:: console
GRANT ALL PRIVILEGES ON trove.* TO 'trove'@'localhost' \
IDENTIFIED BY 'TROVE_DBPASS';
GRANT ALL PRIVILEGES ON trove.* TO 'trove'@'%' \
IDENTIFIED BY 'TROVE_DBPASS';
Replace ``TROVE_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
$ source admin-openrc.sh
#. To create the service credentials, complete these steps:
* Create the ``trove`` user:
.. code-block:: console
$ openstack user create --domain default --password-prompt trove
User Password:
Repeat User Password:
+-----------+-----------------------------------+
| Field | Value |

| enabled | True |
| id | ca2e175b851943349be29a328cc5e360 |
| name | trove |
+-----------+-----------------------------------+
* Add the ``admin`` role to the ``trove`` user:
.. code-block:: console
$ openstack role add --project service --user trove admin
.. note::
This command provides no output.
* Create the ``trove`` service entity:
.. code-block:: console
$ openstack service create --name trove \
--description "Database" database

#. Create the Database service API endpoints:
.. code-block:: console
$ openstack endpoint create --region regionOne \
database public http://controller:8779/v1.0/%\(tenant_id\)s
+--------------+----------------------------------------------+
| Field | Value |

Install and configure components
--------------------------------
.. only:: obs or rdo or ubuntu
.. include:: shared/note_configuration_vary_by_distribution.rst
.. only:: obs
#. Install the packages:
.. code-block:: console
# zypper --quiet --non-interactive install python-oslo.db \
python-MySQL-python
# zypper --quiet --non-interactive install openstack-trove-api \
openstack-trove-taskmanager openstack-trove-conductor \
openstack-trove-guestagent
.. only:: rdo
#. Install the packages:
.. code-block:: console
# yum install openstack-trove python-troveclient
.. only:: ubuntu
#. Install the packages:
.. code-block:: console
# apt-get update
# apt-get install python-trove python-troveclient \
python-glanceclient trove-common trove-api trove-taskmanager \
trove-conductor
.. only:: obs or rdo or ubuntu
2. In ``/etc/trove``, edit the following configuration files,
taking the below actions for each file:
``trove.conf``
``trove-taskmanager.conf``
``trove-conductor.conf``
* Provide appropriate
values for the following settings:
.. code-block:: ini
[DEFAULT]
log_dir = /var/log/trove
trove_auth_url = http://controller:5000/v2.0
nova_compute_url = http://controller:8774/v2
cinder_url = http://controller:8776/v1
swift_url = http://controller:8080/v1/AUTH_
notifier_queue_hostname = controller
...
[database]
connection = mysql://trove:TROVE_DBPASS@controller/trove
* Configure the Database module to use the ``RabbitMQ`` message broker
by setting the following options in the ``[DEFAULT]`` configuration
group of each file:
.. code-block:: ini
[DEFAULT]
...
rpc_backend = rabbit
[oslo_messaging_rabbit]
...
rabbit_host = controller
rabbit_userid = openstack
rabbit_password = RABBIT_PASS
3. Verify that the ``api-paste.ini``
file is present in ``/etc/trove``.
If the file is not present, you can get it from this
`location <http://git.openstack.org/cgit/openstack/trove/plain/etc/trove/api-paste.ini?h=stable/mitaka>`__.
4. Edit the ``trove.conf`` file so it includes appropriate values for the
settings shown below:
.. code-block:: ini
[DEFAULT]
auth_strategy = keystone
...
# Config option for showing the IP address that nova doles out
add_addresses = True
network_label_regex = ^NETWORK_LABEL$
...
api_paste_config = /etc/trove/api-paste.ini
...
[keystone_authtoken]
...
auth_uri = http://controller:5000
auth_url = http://controller:35357
auth_type = password
project_domain_name = default
user_domain_name = default
project_name = service
username = trove
password = TROVE_PASS
5. Edit the ``trove-taskmanager.conf`` file so it includes the required
settings to connect to the OpenStack Compute service as shown below:
.. code-block:: ini
[DEFAULT]
...
# Configuration options for talking to nova via the novaclient.
# These options are for an admin user in your keystone config.
# It proxy's the token received from the user to send to nova
# via this admin users creds,
# basically acting like the client via that proxy token.
nova_proxy_admin_user = admin
nova_proxy_admin_pass = ADMIN_PASS
nova_proxy_admin_tenant_name = service
taskmanager_manager = trove.taskmanager.manager.Manager
6. In ``etc/trove``, edit the ``trove-guestagent.conf`` file
so that future trove guests can connect to your OpenStack environment:
.. code-block:: ini
rabbit_host = controller
rabbit_password = RABBIT_PASS
nova_proxy_admin_user = admin
nova_proxy_admin_pass = ADMIN_PASS
nova_proxy_admin_tenant_name = service
trove_auth_url = http://controller:35357/v2.0
7. Populate the trove database you created earlier in this procedure:
.. code-block:: console
# su -s /bin/sh -c "trove-manage db_sync" trove
...
2016-04-06 22:00:17.771 10706 INFO trove.db.sqlalchemy.migration [-]
Upgrading mysql://trove:dbaasdb@controller/trove to version latest
Finalize installation
---------------------
.. only:: ubuntu
1. Due to a bug in the Ubuntu packages, you need to edit the
service definition files to use the correct configuration settings.
To do this, navigate to ``/etc/init`` and edit the following files
as described below:
``trove-taskmanager.conf``
``trove-conductor.conf``
(Note that, although they have the same names, these files are
in a different location and have different content than the similarly
named files you edited earlier in this procedure.)
In each file, find this line:
.. code-block:: ini
exec start-stop-daemon --start --chdir /var/lib/trove \
--chuid trove:trove --make-pidfile \
--pidfile /var/run/trove/trove-conductor.pid \
--exec /usr/bin/trove-conductor -- \
--config-file=/etc/trove/trove.conf ${DAEMON_ARGS}
Note that ``--config-file`` incorrectly points to ``trove.conf``.
In ``trove-taskmanager.conf``, edit ``config-file`` to point to
``/etc/trove/trove-taskmanager.conf``.
In ``trove-conductor.conf``, edit ``config-file`` to point to
``/etc/trove/trove-conductor.conf``.
2. Restart the Database services:
.. code-block:: console
# service trove-api restart
# service trove-taskmanager restart
# service trove-conductor restart
.. only:: rdo or obs
1. Start the Database services and configure them to start when
the system boots:
.. code-block:: console
# systemctl enable openstack-trove-api.service \
openstack-trove-taskmanager.service \
openstack-trove-conductor.service
# systemctl start openstack-trove-api.service \
openstack-trove-taskmanager.service \
openstack-trove-conductor.service

* `Create a trove image <http://docs.openstack.org/developer/trove/dev/building_guest_images.html>`_.
Create an image for the type of database you want to use, for example,
MySQL, MongoDB, Cassandra.
This image must have the trove guest agent installed.
* Upload the image to glance. Example:
.. code-block:: console
$ glance image-create --name "mysqlTest" --disk-format qcow2 \
--container-format bare \
--file mysql-5.6.qcow2

* Create a datastore. You need to create a separate datastore for
each type of database you want to use, for example, MySQL, MongoDB,
Cassandra. This example shows you how to create a datastore for a
MySQL database:
.. code-block:: console
# su -s /bin/sh -c "trove-manage \
--config-file /etc/trove/trove.conf \
datastore_update mysql ''" trove
...
Datastore 'mysql' updated.
#. Update the datastore to use the new image.
This example shows you how to update a MySQL 5.6 datastore:
.. code-block:: console
# su -s /bin/sh -c "trove-manage --config-file /etc/trove/trove.conf \
datastore_version_update \
mysql mysql-5.6 mysql glance_image_ID '' 1" trove
...
Datastore version 'mysql-5.6' updated.
#. Create a database `instance
<http://docs.openstack.org/user-guide/create_db.html>`_.
