Thanks Julian, it works!
For anyone else that wants to do this I've attached my config.json file below:
{
"url": "http://localhost/forum",
"port": "/tmp/nodeenv.sock",
"secret": "random-secret-here",
"database": "mongo",
"mongo": {
"host": "127.0.0.1",
"port": "27017",
"username": "",
"password": "",
"database": "0"
}
}
