Reconnecting wordpress to a database

A year ago we had a multiuser site that was hosted on a Mac X-server running the old server version that included Apache, php, and mysql. We lost the server hosting location. …

Now we are in the process of setting up a new MacMini at MacMiniVault.

I have Apache running, php running, and mysql running.

I have imported the mysql database into the new MySql

I have the entire web server hierarchy, including the .htaccess and the wp-config.php from the old server in the new server location.

How do I connect the old wordpress installation to the newly imported database.
