To set up phpBB the first thing you'll need to do is create a database. You can find some instructions on doing this in cpanel or plesk below. These settings should help you out with the phpBB installation page:
Database Server Hostname / DSN: localhost
Your Database Name: The name of the database you created in the control panel.
Database Username: The database username you added to the database in your control panel.
Database Password: The password you created for the database username
Prefix for tables in database: phpbb_
Admin Configuration
Admin Email Address: your email address
Domain Name: your domain name
Server Port: 80
Script path: this should be okay to leave with what's auto filled in for you
Administrator Username: Make up your admin username
Administrator Password: Make up your admin password
Administrator Password [ Confirm ]: confrim the admin password you made up
To create a database on Cpanel:
1. Login to your control panel and click on the MySQL icon.
2. Enter a name you'd like to call your database in the Db: input field -> Click Add Db
3. Go back to the MySQL area by clicking the go back link or however esle.
4. Go down to where it says Users: and create a username and password that you'd like to use for your database. -> Click Add User
5. Go back to the MySQL area and in the drop down menus make sure the user you added and the database you added are selected and click Add User to Db.
Also one thing to be aware of on Cpanel is that your username is added as a prefix to databases and database users. So if you set up the database "phpbb" it's actually going to be yourusername_phpbb so you would need to enter yourusername_phpbb as the database name in the phpBB installation page, and of course, replace your_username with your actual username. The same with the db user. you'll notice this if you look at the drop down menu in the MySQL area in your control panel after you've created a database or database user.
