You can configure OpenStack Compute to use any
SQLAlchemy-compatible database. The database name is
nova. The nova-conductor service is the
only service that writes to the database. The other Compute
services access the database through the nova-conductor service.
To ensure that the database schema is current, run the following command:
# nova-manage db sync
If nova-conductor
is not used, entries to the database are mostly written by the
nova-scheduler
service, although all services must be able to update
entries in the database.
In either case, use the configuration option settings documented in Table 4.27, “Description of database configuration options” to configure the connection string for the nova database.
