How to use multiple database in laravel

 Step 1. In the env file write the code as below.

DB_HOST=127.0.0.1
DB_DATABASE=database1
DB_USERNAME=root
DB_PASSWORD=

DB_HOST2=127.0.0.1
DB_DATABASE2=database2
DB_USERNAME2=root
DB_PASSWORD2=

Step 2. In the config/database.php write the code as below.

'mysql' => [
    'driver' => 'mysql',
    'host' => env('DB_HOST', '127.0.0.1'),
    'database' => env('DB_DATABASE', 'database1'),
    'username' => env('DB_USERNAME', 'root'),
    'password' => env('DB_PASSWORD', ''),
    'charset' => 'utf8mb4',
    'collation' => 'utf8mb4_unicode_ci',
    'prefix' => '',
    'strict' => true,
],

'mysql2' => [
    'driver' => 'mysql',
    'host' => env('DB_HOST2', '127.0.0.1'),
    'database' => env('DB_DATABASE2', 'database2'),
    'username' => env('DB_USERNAME2', 'root'),
    'password' => env('DB_PASSWORD2', ''),
    'charset' => 'utf8mb4',
    'collation' => 'utf8mb4_unicode_ci',
    'prefix' => '',
    'strict' => true,
],

Step 3. In the model file add a line as below.
  
         protected $connection = 'mysql2';

Step 4.  

use App\Models\User;

class UsersController extends BaseController
{
   class Order extends Model
   {
      protected $connection = 'mysql2';
      protected $table = 'orders';
  }    
}

 

With Query Builder

$data1 = DB::connection('mysql')->table('users')->get(); // DB 1
$data2 = DB::connection('mysql2')->table('orders')->get(); // DB 2
