First Steps > Create a database
A second additional option when creating a new host is the “Create a database” checkbox. This will add a database associated with your new host. Choose “root” as the database user. A new databse will be created for the “root” MySQL user. This database will be associated with your host which can be confirmed on the Settings > Hosts > Databases tab.
More information about adding a database user and granting rights can be found in the Settings > Hosts > Hosts table section.
