Ich bin neu bei PHP und mir wurde kürzlich ein Job für eine Anwendung (PHP/Laravel) angeboten, die auf einem Server (AWS) mit MySQL und RDS läuft, wobei Nginx den App-/PHP-Inhalt hostet

Dies ist die Datei, die den Nginx-Pfad in /etc/nginx/conf.d definiert

Ich habe den Quellcode, aber der vorherige Freelancer hat die Zusammenarbeit mit dem Kunden eingestellt. Ich habe keine Datenbankanmeldeinformationen, ich muss auf die Datenbank zugreifen, kann es aber nicht. Ich habe versucht, in der PHP-Datei nach dem Passwort zu suchen, und alles, was ich finden konnte, war ein Konfigurationsordner mit einer Datei „database.php“ mit folgendem Inhalt:

'connections' => [

        'sqlite' => [
            'driver' => 'sqlite',
            'database' => env('DB_DATABASE', database_path('database.sqlite')),

Ich habe die Umgebungsvariablen mit printenv überprüft, kann aber keine Umgebungsvariablen wie DB_USERNAME finden. Da die Anwendung einwandfrei läuft, kann sie eine Verbindung zur Datenbank herstellen.

So erhalten Sie die Anmeldeinformationen der Datenbank. Gibt es eine Möglichkeit herauszufinden, wie die Anwendung eine Verbindung zur Datenbank herstellt und einwandfrei funktioniert?
