Laravel auth problems

First problem is error when I'm using route without index.php: The requested URL /auth/login was not found on this server. I found that this error may appears when mod_rewrite isn't set, but it is.

Second problem is PDO error: PDOException in Connector.php line 50: SQLSTATE[HY000] [2005] Unknown MySQL server host 'localhost:3306' (2) I found that this may appear because DB_HOST is set 'localhost:3306' on PHP 5.5 and higher, but it's set 'localhost'
