Laravel的工匠無法連接到數據庫，拋出錯誤 「SQLSTATE [HY000] [2002年]」

Question

我有以下遷移：

<?php 

class Create_Users_Table { 

    /** 
    * Make changes to the database. 
    * 
    * @return void 
    */ 
    public function up() 
    { 
     Schema::create('users', function($table){ 
      $table->increments('id'); 
      $table->string('username'); 
      $table->string('password'); 
      $table->timestamps(); 
     }); 
    } 

    /** 
    * Revert the changes to the database. 
    * 
    * @return void 
    */ 
    public function down() 
    { 
     Schema::drop('users'); 
    } 

} 

當我運行php artisan migrate，我得到以下錯誤：

Warning: PDO::__construct(): [2002] No connection could be made because the target machine actively (trying to connect via tcp://127.0.0.1:3306) in C:\xampp\htdocs\snip\laravel\database\connectors\mysql.php on line 33

SQLSTATE[HY000] [2002] No connection could be made because the target machine actively refused it. 

我在運行PHP 5.4的Win7和XAMPP上。有什麼我失蹤？

編輯：這裏是內database.php中的DB配置：

'connections' => array(

     ... 

     'mysql' => array(
      'driver' => 'mysql', 
      'host'  => '127.0.0.1', 
      'database' => 'makeitsnappy', 
      'username' => 'root', 
      'password' => '', 
      'charset' => 'utf8', 
      'prefix' => '', 
     ), 
... 
) 

而且，在目標機器是我的本地服務器和我有過它的完全控制。

DB配置存在問題。檢查您的dsn字符串或主機名和db驅動程序類型。
