Install and configure for Ubuntu

This section describes how to install and configure the Database service for Ubuntu 14.04 (LTS).

Prerequisites

Before you install and configure the Database 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 trove database:

      CREATE DATABASE trove;

    • Grant proper access to the trove database:

      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.

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

    $ . admin-openrc

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

    • Create the trove user:

      $ openstack user create --domain default --password-prompt trove
User Password:
Repeat User Password:
+-----------+-----------------------------------+
| Field     | Value                             |
+-----------+-----------------------------------+
| domain_id | default                           |
| enabled   | True                              |
| id        | ca2e175b851943349be29a328cc5e360  |
| name      | trove                             |
+-----------+-----------------------------------+

    • Add the admin role to the trove user:

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

      Note

      This command provides no output.

    • Create the trove service entity:

      $ openstack service create --name trove \
  --description "Database" database
+-------------+-----------------------------------+
| Field       | Value                             |
+-------------+-----------------------------------+
| description | Database                          |
| enabled     | True                              |
| id          | 727841c6f5df4773baa4e8a5ae7d72eb  |
| name        | trove                             |
| type        | database                          |
+-------------+-----------------------------------+

  4. Create the Database service API endpoints:

    $ openstack endpoint create --region RegionOne \
  database public http://controller:8779/v1.0/%\(tenant_id\)s
+--------------+----------------------------------------------+
| Field        | Value                                        |
+--------------+----------------------------------------------+
| enabled      | True                                         |
| id           | 3f4dab34624e4be7b000265f25049609             |
| interface    | public                                       |
| region       | RegionOne                                    |
| region_id    | RegionOne                                    |
| service_id   | 727841c6f5df4773baa4e8a5ae7d72eb             |
| service_name | trove                                        |
| service_type | database                                     |
| url          | http://controller:8779/v1.0/%\(tenant_id\)s  |
+--------------+----------------------------------------------+

$ openstack endpoint create --region RegionOne \
  database internal http://controller:8779/v1.0/%\(tenant_id\)s
+--------------+----------------------------------------------+
| Field        | Value                                        |
+--------------+----------------------------------------------+
| enabled      | True                                         |

| service_name | trove                                        |

Install and configure components

  1. Install the packages:

    # apt-get update

# apt-get install python-trove python-troveclient \
  python-glanceclient trove-common trove-api trove-taskmanager \
  trove-conductor

  1. In the /etc/trove directory, edit the trove.conf, trove-taskmanager.conf and trove-conductor.conf files and complete the following steps:

    • Provide appropriate values for the following settings:

      [DEFAULT]
log_dir = /var/log/trove
trove_auth_url = http://controller/identity/v2.0
nova_compute_url = http://controller:8774/v2
cinder_url = http://controller:8776/v1
swift_url = http://controller:8080/v1/AUTH_
...
[database]
connection = mysql+pymysql://trove:TROVE_DBPASS@controller/trove

    • Configure the Database service to use the RabbitMQ message broker by setting the following options in each file:

      [DEFAULT]
...
rpc_backend = rabbit

[oslo_messaging_rabbit]
...
rabbit_host = controller
rabbit_userid = openstack
rabbit_password = RABBIT_PASS

  2. 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.

  3. Edit the trove.conf file so it includes appropriate values for the settings shown below:

    [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/identity
auth_url = http://controller/identity_admin
auth_type = password
project_domain_name = default
user_domain_name = default
project_name = service
username = trove
password = TROVE_PASS

  4. Edit the trove-taskmanager.conf file so it includes the required settings to connect to the OpenStack Compute service as shown below. Include ConfigDrive settings so that configuration is injected into the Guest VM. And finally, if using Nova Network, set the the network driver name and a regex which allows Projects to launch Guests on any of their networks.

    [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

# Inject configuration into guest via ConfigDrive
use_nova_server_config_drive = True

# Set these if using Neutron Networking
network_driver=trove.network.neutron.NeutronDriver
network_label_regex=.*

  5. Edit the /etc/trove/trove-guestagent.conf file so that future trove guests can connect to your OpenStack environment:

    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/identity_admin/v2.0

  6. Populate the trove database you created earlier in this procedure:

    # 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+pymysql://trove:dbaasdb@controller/trove to version latest

    Note

    Ignore any deprecation messages in this output.

Finalize installation

  1. Due to a bug in the Ubuntu packages, 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:

    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:

    # service trove-api restart
# service trove-taskmanager restart
# service trove-conductor restart
