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.

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:
```
$ 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
+-------------+-----------------------------------+
| Field       | Value                             |
+-------------+-----------------------------------+
| description | Database                          |
| enabled     | True                              |
| id          | 727841c6f5df4773baa4e8a5ae7d72eb  |
| name        | trove                             |
| type        | database                          |
+-------------+-----------------------------------+

Create the Database service API endpoints:

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

obs or rdo or ubuntu

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: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 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

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 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: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

Edit the trove-taskmanager.conf file so it includes the required settings to connect to the OpenStack Compute service as shown below:

[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

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:35357/v2.0

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://trove:dbaasdb@controller/trove to version latest

Note

Ignore any deprecation messages in this output.

Finalize installation

ubuntu

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.

Restart the Database services:

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

rdo or obs

Start the Database services and configure them to start when the system boots:

# 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
