Laravel沒有連接mysql數據庫

我是laravel中的新手也在stackoverflow中，我試圖在我的laravel應用程序中配置數據庫。但它不起作用，並總是向我顯示錯誤。這裏是我的database.php文件。Laravel沒有連接mysql數據庫

database.php中

<?php 

return [ 

    /* 
    |-------------------------------------------------------------------------- 
    | PDO Fetch Style 
    |-------------------------------------------------------------------------- 
    | 
    | By default, database results will be returned as instances of the PHP 
    | stdClass object; however, you may desire to retrieve records in an 
    | array format for simplicity. Here you can tweak the fetch style. 
    | 
    */ 

    'fetch' => PDO::FETCH_CLASS, 

    /* 
    |-------------------------------------------------------------------------- 
    | Default Database Connection Name 
    |-------------------------------------------------------------------------- 
    | 
    | Here you may specify which of the database connections below you wish 
    | to use as your default connection for all database work. Of course 
    | you may use many connections at once using the Database library. 
    | 
    */ 

    'default' => 'mysql', 

    /* 
    |-------------------------------------------------------------------------- 
    | Database Connections

    | 
    | Here are each of the database connections setup for your application.

    | supported by Laravel is shown below to make development simple. 
    | 
    | 
    | All database work in Laravel is done through the PHP PDO facilities 
    | so make sure you have the driver for your particular database of

    | 
    */ 

    'connections' => [ 

     'sqlite' => [ 
      'driver' => 'sqlite', 
      'database' => storage_path().'/database.sqlite', 
      'prefix' => '', 
     ], 

     'mysql' => [ 
      'driver' => 'mysql', 
      'host'  => 'localhost', 
      'database' => 'horsi', 
      'username' => 'root', 
      'password' => '', 
      'charset' => 'utf8', 
      'collation' => 'utf8_unicode_ci', 
      'prefix' => '', 
      'strict' => false, 
     ], 

     'pgsql' => [ 
      'driver' => 'pgsql', 
      'host'  => env('DB_HOST', 'localhost'), 
      'database' => env('DB_DATABASE', 'horsi'), 
      'username' => env('DB_USERNAME', 'root'), 
      'password' => env('DB_PASSWORD', ''), 
      'charset' => 'utf8', 
      'prefix' => '', 
      'schema' => 'public', 
     ], 

     'sqlsrv' => [ 
      'driver' => 'sqlsrv', 
      'host'  => env('DB_HOST', 'localhost'), 
      'database' => env('DB_DATABASE', 'horsi'), 
      'username' => env('DB_USERNAME', 'root'), 
      'password' => env('DB_PASSWORD', ''), 
      'prefix' => '', 
     ], 

    ],

    'migrations' => 'migrations',

    | 
    */ 

    'redis' => [ 

     'cluster' => false, 

     'default' => [ 
      'host'  => '127.0.0.1', 
      'port'  => 6379, 
      'database' => 0, 
     ], 

    ], 

];

我還附上我的.ENV文件

APP_ENV=local 
APP_DEBUG=true 
APP_KEY=SomeRandomString 

DB_HOST=localhost 
DB_DATABASE=horsi 
DB_USERNAME=root 
DB_PASSWORD= 

CACHE_DRIVER=file 
SESSION_DRIVER=file 
QUEUE_DRIVER=sync 

MAIL_DRIVER=smtp 
MAIL_HOST=mailtrap.io 
MAIL_PORT=2525 
MAIL_USERNAME=null 
MAIL_PASSWORD=null

我也試圖配置我的數據庫就像

'host'  => env('DB_HOST', 'localhost'), 
      'database' => env('DB_DATABASE', 'horsi'), 
      'username' => env('DB_USERNAME', 'root'), 
      'password' => env('DB_PASSWORD', ''),

但它不是工作，任何人都可以幫助我獲得解決方案

錯誤：空到位的用戶名和poassword

它顯示什麼錯誤？例如，如果您嘗試使用'localhost'作爲主機連接到數據庫，而使用'root'連接到沒有MySQL Workbench密碼的數據庫，您能夠連接嗎？ –

請不要使用[mysql_'數據庫擴展]（http://stackoverflow.com/questions/12859942/why-shouldnt-i-use-mysql-functions-in-php），它已被棄用（永遠不會在PHP7中）特別是，如果你只是學習PHP，花費你的精力學習'PDO'數據庫擴展。 [從這裏開始]（http://php.net/manual/en/book.pdo.php） – RiggsFolly

壞主意。不要使用mysql_。你在內部架構中使用框架。它使用PDO。請檢查我的答案。 – Dinar

嘗試添加此行

'default' => env('DB_DEFAULT', 'mysql')

，而不是地方的

'default' => 'mysql'

並在.env文件中設置

而在這種情況下還需要添加到'.env 'file' DB_DEFAULT = mysql' – Dinar

是的，我們需要.env文件，對於這種情況 –

您可以使用默認的數據庫爲'default' => 'mysql'

但.env CONFIGS在您的配置文件會爲pgsql。

所以，如果你要使用MySQL，設置這個

'host'  => env('DB_HOST', 'localhost'), 
'database' => env('DB_DATABASE', 'horsi'), 
'username' => env('DB_USERNAME', 'root'), 
'password' => env('DB_PASSWORD', ''),

爲mysql部分在config.php
