The OpenStack Compute service uses its own database called the Nova database. This database must be up and running for the other Nova services to function properly.
If you happen to encounter any database-related error messages in the log files, you should first check the database by connecting to it using the MySQL command line:
# mysql -u nova -p -h packtpub-dbserver nova
If the connection is successful, you should ensure that all the tables are present in the database:
# show tables
If there are no tables present, you can initialize the database by invoking the following command:
# nova-manage db sync
This will create the required tables and the Nova services should come back online.
