I have setup Laravel and trying to run the artisan migrate command however I am getting the error [PDOException]
SQLSTATE[HY000] [2002] Connection refused.

I am not sure how db is setup in Homestead. So I got the below questions.

1. Is default database created automatically by artisan migrate or Homestead? If it is, what is the name?
2. If its not created by default, should we create before running migration?
3. I tried loggin in to MySQL db by connecting to Homestead VM using ssh and then running MySQL. However I get error "Access denied for user...." for user name vagrant, Homestead and forge. What is the default credentials?

I understand that creating MySQL db is out of the scope of Laravel tutorial; So it would be helpful if anyone can answer these questions and point me in right direction. Thanks.
