无法迁移Pagodabox项目的数据库

I'm following the Hands-On project for course Laravel Essentails on Tutsplus. I created an app on PagodaBox and cloned it into my local system. After that, I install Laravel-4-Generator from https://github.com/JeffreyWay/Laravel-4-Generators and generated resources for my project: model, view, controller, database seed, etc. Next, I try to run

php artisan migrate:install snippets

But I got the following error:

[PDOException]                                                                               
SQLSTATE[HY000] [1045] Access denied for user 'homestead'@'localhost' (using password: YES)  

I don't know what's homestead user here. Here is my database file for this project

'default' => 'mysql',
'connections' => array(

    'sqlite' => array(
        'driver'   => 'sqlite',
        'database' => __DIR__.'/../database/production.sqlite',
        'prefix'   => '',
    ),

    'mysql' => array(
        'driver'    => 'mysql',
        'host'      => isset($_SERVER['DB1_HOST']) ? $_SERVER['DB1_HOST'] : 'localhost',
        'database'  => isset($_SERVER['DB1_NAME']) ? $_SERVER['DB1_NAME'] : 'snippets',
        'username'  => isset($_SERVER['DB1_USER']) ? $_SERVER['DB1_USER'] : 'root',
        'password'  => isset($_SERVER['DB1_PASS']) ? $_SERVER['DB1_PASS'] : '',
        'charset'   => 'utf8',
        'collation' => 'utf8_unicode_ci',
        'prefix'    => '',
    ),

And here is the result when I check grants for 'homestead'@'localhost':

mysql> SHOW GRANTS FOR 'homestead'@'localhost';
+---------------------------------------------------------------------------------------------------------------------------------------------+
| Grants for homestead@localhost                                                                                                              |
+---------------------------------------------------------------------------------------------------------------------------------------------+

+---------------------------------------------------------------------------------------------------------------------------------------------+

P/S: I have created the snippets database in mysql and I'm an Ubuntu 14.04 machine. Has anyone experienced this before. What should I do as I don't understand what the error is here.

View Users created:

mysql> select user,host from mysql.user;
+------+----------------------+
| user | host                 |
+------+----------------------+
| root | %                    |
| root | 127.0.0.1            |
| root | ::1                  |
| root | imac.de.yadira.local |
|      | localhost            |
| root | localhost            |
|      | mor-mac.local     |
+------+----------------------+
7 rows in set (0.00 sec)

copy imac.de.yadira.local and replace hostname in my case it was mor-mac.local

$env = $app->detectEnvironment(array(

    'local' => array('imac.de.yadira.local'),

));

and now runs:

mor-mac:resposive yadira$ php artisan migrate:install
Migration table created successfully.
