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  |
+--------------+----------------------------------------------+

  database internal http://controller:8779/v1.0/%\(tenant_id\)s
+--------------+----------------------------------------------+
| Field        | Value                                        |

Install and configure components

  1. Install the packages:

    Warning

    Please be aware that the trove debian packages for Ubuntu are not usually up to date, especially when there are bugfixes for stable branch, the debian packages are not guaranteed to contain those changes. The recommended way to install OpenStack services is either using docker image with source code or installing source code inside a Python virutual environment.

    The commands to install Trove compoments:

    # apt-get update
# apt-get install python-trove trove-common trove-api trove-taskmanager trove-conductor
# pip3 install python-troveclient

  1. In the /etc/trove directory, edit the trove.conf file, here is an example:

    [DEFAULT]
network_driver = trove.network.neutron.NeutronDriver
management_networks = ef7541ad-9599-4285-878a-e0ab62032b03
management_security_groups = d0d797f7-11d4-436e-89a3-ac8bca829f81
cinder_volume_type = lvmdriver-1
nova_keypair = trove-mgmt
default_datastore = mysql
taskmanager_manager = trove.taskmanager.manager.Manager
trove_api_workers = 5
transport_url = rabbit://stackrabbit:password@192.168.1.34:5672/
control_exchange = trove
rpc_backend = rabbit
reboot_time_out = 300
usage_timeout = 900
agent_call_high_timeout = 1200
use_syslog = False
debug = True

[keystone_authtoken]
memcached_servers = localhost:11211
cafile = /devstack/stack/data/ca-bundle.pem
project_domain_name = Default
project_name = service
user_domain_name = Default
password = password
username = trove
auth_url = http://192.168.1.34/identity
auth_type = password

[service_credentials]
auth_url = http://192.168.1.34/identity/v3
region_name = RegionOne
project_name = service
password = password
project_domain_name = Default
user_domain_name = Default
username = trove

[database]
connection = mysql+pymysql://root:password@127.0.0.1/trove?charset=utf8

[mariadb]
tcp_ports = 3306,4444,4567,4568

[mysql]
tcp_ports = 3306

[postgresql]
tcp_ports = 5432

  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 /etc/trove/trove-guestagent.conf file so that future trove guests can connect to your OpenStack environment, here is an example:

    [DEFAULT]
log_file = trove-guestagent.log
log_dir = /var/log/trove/
ignore_users = os_admin
control_exchange = trove
transport_url = rabbit://stackrabbit:password@172.24.5.1:5672/
rpc_backend = rabbit
command_process_timeout = 60
use_syslog = False
debug = True

[service_credentials]
auth_url = http://192.168.1.34/identity/v3
region_name = RegionOne
project_name = service
password = password
project_domain_name = Default
user_domain_name = Default
username = trove

  4. 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. Restart the Database services:

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