This section describes how to install and configure the Database service for Ubuntu 14.04 (LTS).
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:
$ 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.
Source the admin
credentials to gain access to
admin-only CLI commands:
$ . admin-openrc
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

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

+--------------+----------------------------------------------+
$ openstack endpoint create --region RegionOne \
database admin http://controller:8779/v1.0/%\(tenant_id\)s

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
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
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.
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
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.
Restart the Database services:
# service trove-api restart
# service trove-taskmanager restart
# service trove-conductor restart
