If an app requires a database, Plesk creates it automatically during
installation of the app. To create a database, Plesk uses app database
settings, which you can change in the Main configuration section
(Show All Settings link) when installing an app:
- A database name and a database server where the app will store the
database. - Database user credentials, which Plesk will use to access the app
database. It may be convenient to employ a single database user with
access to all databases. In this case, you can create a universal
user account and specify it when installing apps. To learn more,
refer to the section Managing Database User Accounts.
Note that if you exceed the maximum number of databases allowed for your
subscription, a new app does not create a database. Instead, it adds
tables to one of the existing databases, and adds prefixes to table
names. Prefixes make it easier to distinguish tables of different apps
from each other. For example, the WordPress app will add the
“ wpress_ ” prefix to the names of its tables.
