如何强制 Laravel 使用不同的 mysql 数据库？

Question

I'm running a Laravel 5.2 app on an EC2 instance with Ubuntu. For some reason the app is telling me I'm using a database other then what I've defined on the env file. My .env file is as such:

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

But the application is throwing the error

SQLSTATE[42S02]: Base table or view not found: 1146 Table 'phpmyadmin.products_list`

I've ran

php artisan optimize

which yield Generating optimized class loader and then I ran

php artisan migrate

which resulted in Nothing to migrate .

I've several databases on MySQL server as listed below and I want the application to use the database paidfor and not phpmyadmin .

information_schema
mysql
paidfor
performance_schema
phpmyadmin

How can I fix this issue?

If you updated the .env file and ran php artisan optimize and it still doesn't work, then there's one of two things that could happen:

1. You're not using the values of .env for the database connection.

   Open the file config/database.php and look for the connections key. Verify that you're using the values of env on the connection name (in your case mysql ). You should have something like:

    '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, ],

2. Your model is using another connection rather than mysql . Check the model for something like

    $this->connection = 'other-connection-name';

   or something like

   $this->setConnection('other-connection-name');

If you wish to use paidfor database in your system, and access from phpmyadmin, create a new user for application with these privileges: ALTER, CREATE, DELETE, DROP, INDEX, INSERT, SELECT, UPDATE (you could, also, create two users, one for migrations only and other for application).

With you root user, run in your PhpMyAdmin:

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

After that, use your new user in your .env file.

Then when you access PhpMyAdmin, with your new user, you will have access only to this database.

Don't ever never ever use root user in your application

A solution could not be found with the instance I was running because the server was ignoring the .emv file. The only workaround I could figure out was to boot up a brand new EC2 instance, reinstall Composer, Laravel, and try again.

Special thanks to @milz for spending about 2 hours working through this with me!
