OpenStack Release: Train

Installing Trove Packages

Execute the package installation command on the controller node to deploy the necessary Trove components.

yum install -y openstack-trove-guestagent openstack-trove python-troveclient openstack-trove-ui

Database and Service Credential Configuration

Access the database server to create the Trove database and grant appropriate access rights.

mysql -u root -p
CREATE DATABASE trove;
GRANT ALL PRIVILEGES ON trove.* TO 'trove'@'localhost' IDENTIFIED BY 'TroveDBPass123';
GRANT ALL PRIVILEGES ON trove.* TO 'trove'@'%' IDENTIFIED BY 'TroveDBPass123';
FLUSH PRIVILEGES;
exit;

Create the service user and API endpoints in Keystone.

openstack user create --domain default --password TroveUserPass123 trove
openstack role add --project service --user trove admin
openstack service create --name trove --description "Database as a Service" database

openstack endpoint create --region RegionOne database public http://ctrl-node:8779/v1.0/%\(tenant_id\)s
openstack endpoint create --region RegionOne database internal http://ctrl-node:8779/v1.0/%\(tenant_id\)s
openstack endpoint create --region RegionOne database admin http://ctrl-node:8779/v1.0/%\(tenant_id\)s

Key parameters requiring environment-specific substitution include:

• Administrator Project ID: nova_proxy_admin_tenant_id
• Neutron Network ID: default_neutron_networks
• Keystone Auth URL: trove_auth_url
• Object Storage URL: swift_url (must include the project ID suffix)

Database Initialization

Populate the Trove database schema.

su -s /bin/sh -c "trove-manage db_sync" trove

If the command fails with a missing module error for MySQLdb, install the appropriate Python database driver.

pip install MySQL-python
# Or for Python 3 environments:
pip install mysqlclient

Rerun the synchronization command after package installation.

Service Activation

Restart the web server and enable the Trove services to start on boot.

systemctl restart httpd
systemctl enable openstack-trove-api.service openstack-trove-taskmanager.service openstack-trove-conductor.service
systemctl restart openstack-trove-api.service openstack-trove-taskmanager.service openstack-trove-conductor.service
