Manage databases and users on Trove instances
Assume that you installed Trove service and uploaded images with datastore of your choice. This section shows how to manage users and databases in a MySQL 5.7 instance.
Add new database and user to an existing Trove instance
Trove provides API to manage users and databases on datastores including relational (e.g. MySQL, PostgreSQL) and non-relational (e.g. Redis, Cassandra). Once a Trove instance with a datastore of choice is active you can use Trove API to create new databases and/or users.
$ openstack database user list db-instance

| Name | Host | Databases |

| test | % | testdb |
+------+------+-----------+
$ openstack database user create db-instance newuser userpass --databases testdb
$ openstack database user list db-instance

ERROR 1044 (42000): Access denied for user 'newuser'@'%' to database 'newdb'Manage access to databases
With Trove API you can grant and revoke database access rights for existing users.
$ openstack database user grant access db-instance newuser newdb
$ openstack database user show access db-instance newuser
+--------+
| Name |
+--------+
| newdb |
| testdb |
+--------+
$ mysql -h IP_ADDRESS -u newuser -p newdb
Enter password:
$ openstack database user show access db-instance test
+--------+
| Name |
+--------+
| testdb |
+--------+
$ mysql -h IP_ADDRESS -u test -p newdb
Enter password:
ERROR 1044 (42000): Access denied for user 'test'@'%' to database 'newdb'
$ openstack database user revoke access db-instance newuser newdb
$ mysql -h IP_ADDRESS -u newuser -p newdb
Enter password:
ERROR 1044 (42000): Access denied for user 'newuser'@'%' to database 'newdb'Delete databases
Lastly, Trove provides API for deleting databases.
$ openstack database db list db-instance
+--------+
| Name |
+--------+
| newdb |
| sys |
| testdb |
+--------+
$ openstack database db delete db-instance testdb
$ openstack database db list db-instance
+--------+
| Name |
+--------+
| newdb |
| sys |

$ mysql -h IP_ADDRESS -u test -p testdb
Enter password:
