使用 Laravel 5.7 设置本地开发数据库

Question

我在我的托管平台 Cloudways 上创建了一个新的 Laravel 应用程序 (Laravel 5.7)。 Cloudways 很方便，因为您可以直接从他们的界面安装新的 Laravel 版本，而不是在本地创建一个，然后推送到服务器。

无论如何，我创建了构建，并将文件下载到我的本地机器上。在以前的 Laravel 版本中，我似乎记得只能编辑 .env 文件以指向我的本地数据库（目前是运行到 MAMP/phpMyAdmin）

我确保创建了一个新数据库，然后更新了 .env 文件以指向该数据库。

但是，每当我尝试运行迁移时，它仍然想要指向 database.php 配置文件中指定的数据库连接。

更新 .env 文件后，我确实尝试运行两者：

php artisan config:clear
php artisan cache:clear

但似乎都没有任何影响。每次尝试运行迁移时，我仍然遇到错误。

我似乎找不到任何关于如何从生产数据库指定不同的本地开发数据库的进一步文档。

有人可以提供帮助吗？

编辑：

在 MAMP 上，我的本地设置好像是：

Host:   localhost
Port:   8889
User:   root
Password:   root

我当前的 .env 文件内容：

APP_NAME=Laravel
APP_ENV=local
APP_KEY=base64:Z2ndcYy3H7GMfmEW1rKYxYAxMMjyyAWAsoS+9Q3yppc=
APP_DEBUG=true
APP_URL=http://localhost

LOG_CHANNEL=stack

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=8889
DB_DATABASE=scoutsafe
DB_USERNAME=root
DB_PASSWORD=root

BROADCAST_DRIVER=log
CACHE_DRIVER=file
QUEUE_CONNECTION=sync
SESSION_DRIVER=file
SESSION_LIFETIME=120

REDIS_HOST=127.0.0.1
REDIS_PASSWORD=null
REDIS_PORT=6379

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

PUSHER_APP_ID=
PUSHER_APP_KEY=
PUSHER_APP_SECRET=
PUSHER_APP_CLUSTER=mt1

MIX_PUSHER_APP_KEY="${PUSHER_APP_KEY}"
MIX_PUSHER_APP_CLUSTER="${PUSHER_APP_CLUSTER}"

以及我目前的database.php内容：

    return array(

您的 mysql 配置是硬编码的。您必须像这样更新 database.php 才能使用 .env:

中的变量

'connections' => [
    // Other connection options

    'mysql' => [
        // Other mysql options
        'host' => env('DB_HOST', '127.0.0.1'),
        'port' => env('DB_PORT', '3306'),
        'database' => env('DB_DATABASE', 'forge'),
        'username' => env('DB_USERNAME', 'forge'),
        'password' => env('DB_PASSWORD', ''),
        // Other mysql options
    ],
],
