Question

我正在使用Ubuntu在EC2实例上运行Laravel 5.2应用程序。出于某种原因，应用程序告诉我我正在使用数据库，而不是我在env文件中定义的数据库。我的.env文件是这样的：

APP_ENV=production
APP_DEBUG=true
APP_KEY=snipsnip
APP_URL=http://localhost

DB_CONNECTION=mysql
DB_HOST=paidfor
DB_PORT=
DB_DATABASE=paidfor
DB_USERNAME=root
DB_PASSWORD=snipsnip

CACHE_DRIVER=file
SESSION_DRIVER=file
QUEUE_DRIVER=sync

REDIS_HOST=127.0.0.1
REDIS_PASSWORD=null
REDIS_PORT=6379

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

但是应用程序正在抛出错误

SQLSTATE [42S02]：未找到基表或视图：1146表'phpmyadmin.products_list`

我跑了

php artisan optimize

产生生成优化的类加载器然后我运行

php artisan migrate

导致无法迁移。

我在MySQL服务器上有几个数据库，如下所示，我希望应用程序使用数据库paidfor而不是phpmyadmin。

information_schema
mysql
paidfor
performance_schema
phpmyadmin

如何解决此问题？

您没有将php artisan optimize的值用于数据库连接。

打开文件.env并查找config/database.php键。验证您是否在连接名称上使用了env的值（在您的情况下为connections）。你应该有类似的东西：
```
mysql
```
您的模型正在使用其他连接，而不是'mysql' => [ 'driver' => 'mysql', 'host' => env('DB_HOST', 'localhost'), 'port' => env('DB_PORT', '3306'), 'database' => env('DB_DATABASE', 'forge'), 'username' => env('DB_USERNAME', 'forge'), 'password' => env('DB_PASSWORD', ''), 'charset' => 'utf8', 'collation' => 'utf8_unicode_ci', 'prefix' => '', 'strict' => false, 'engine' => null, ],。检查模型是否类似
```
mysql
```
或类似
```
 $this->connection = 'other-connection-name';
```

Answer 2

如果您希望在系统中使用paidfor数据库，并从phpmyadmin访问，请为具有以下权限的应用程序创建新用户：ALTER, CREATE, DELETE, DROP, INDEX, INSERT, SELECT, UPDATE（您也可以创建两个用户，一个用于仅限迁移和其他应用程序）。

以root用户身份运行PhpMyAdmin：

CREATE USER 'myuser'@'myhost' IDENTIFIED BY 'mypassword';
GRANT ALL PRIVILEGES ON paidfor TO 'myuser'@'myhost';

之后，在.env文件中使用新用户。

然后，当您使用新用户访问PhpMyAdmin时，您将只能访问此数据库。

永远不要在您的应用程序中使用root用户

在我运行的实例中找不到解决方案，因为服务器忽略了.emv文件。我能想到的唯一解决方法是启动一个全新的EC2实例，重新安装Composer，Laravel，然后重试。

特别感谢@milz花了大约2个小时与我一起工作！
