Database creation on master

We have installed the MySQL database server on the master node. Before we continue to the next step in the Ambari wizard, we have to create a new database and assign a few privileges:

We also have to register the JDBC driver using the ambari-server setup command:

bash-$ sudo ambari-server setup --jdbc-db=mysql --jdbc-driver=/usr/share/java/mysql-connector-java.jar
Using python /usr/bin/python
Setup ambari-server
Copying /usr/share/java/mysql-connector-java.jar to /var/lib/ambari-server/resources
If you are updating existing jdbc driver jar for mysql with mysql-connector-java.jar. Please remove the old driver jar, from all hosts. Restarting services that need the driver, will automatically copy the new jar to the hosts.
JDBC driver was successfully initialized.
Ambari Server 'setup' completed successfully.

After this step, we can go back to the Ambari wizard.
