Laravel 5.1 - Homestead MySQL connection. `Connection Refused` & `No such file or directory`

Question

When my .env file is like this:

 DB_HOST=127.0.0.1
 DB_DATABASE=homestead
 DB_USERNAME=homestead
 DB_PASSWORD=secret

Terminal php artisan migrate works successful but on localhost test, it throws:

PDOException in Connector.php line 50:

SQLSTATE[HY000] [2002] Connection refused

But when my .env file is like this:

 DB_HOST=localhost
 DB_DATABASE=homestead
 DB_USERNAME=homestead
 DB_PASSWORD=secret

On localhost everything (registration) works well however php artisan migrate on terminal throws:

[PDOException] SQLSTATE[HY000] [2002] No such file or directory

My database.php file:

      'mysql' => [
        'driver'    => 'mysql',
        'host'      => env('DB_HOST', 'localhost'),
        'database'  => env('DB_DATABASE', 'homestead'),
        'username'  => env('DB_USERNAME', 'homestead'),
        'password'  => env('DB_PASSWORD', 'secret'),
        'port'      => '33060',
        'charset'   => 'utf8',
        'collation' => 'utf8_unicode_ci',
        'prefix'    => '',
        'strict'    => false,
    ],

Answer 1

Inside the VM the sql port is 3306. Outside of the homestead VM the host machine just has a forward to the SQL port on the homestead VM. That is why 33060 points to 3306.
