Nearly all web applications have a database back-end that require a MySQL database. During the application's installation, you will be asked for these database details:
MySQL Host - This is always "localhost"
Username - The user assigned to the database with adequate permissions to manipulate it.
Password - The password for the user assigned to the database.
Database Name - The name of the database you want the application to use.
Databases can be created and configured by using the "MySQL Database Wizard" within cPanel.
