mysql - 使用 Laravel 5 设置 Mariadb

Question

我一直在尝试使用 MariaDB 将我的数据库连接设置为 Laravel 但没有成功，执行我的应用程序返回此错误:

PDOException in Connector.php line 47:
SQLSTATE[HY000] [1049] Unknown database 'data'

这是我的 Database.php 文件:

'default' => 'mysql',

'connections' => [

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

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

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

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

    ],

这是我的 .env 文件:

APP_ENV=local
APP_DEBUG=true
APP_KEY=ZP9Ao5RJhZjS7EqJuaYRltSIC7HTL4vp

DB_HOST=localhost
DB_DATABASE=data
DB_USERNAME=root
DB_PASSWORD=secret

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

这个错误转储:

我认为这与 Mysql 和 MariaDB 之间的某种冲突有关。如果任何已经尝试将 MariaDB 与 Laravel 结合使用的人可以提供示例或经验，那将会很有帮助。 奇怪的是我已经能够使用“php artisan:migrate”执行我的迁移文件，并且数据库确实存在并带有适当的表。迁移脚本如何连接到数据库和 Controller 失败？我做错了什么？

我终于解决了这个问题，因为我使用的是 Homestead，一个 laravel vagrant box 来执行我的网站，该网站实际上试图连接到位于 Homestead 内部的内部 mysql，而我永远无法访问 MariaDB。我仍然不知道如何在 Homestead 中使用 MariaDB，但至少我现在缩小了搜索范围。
