Laravel makes connecting with MySQL databases and running queries extremely simple out of the box. The MySQL database configuration for your application is located at Laravel Project Root Folder, config/database.php. In this file you may define MySQL database connection for your Laravel Application.

'mysql' => [
    'driver' => 'mysql',
    'host' => env('DB_HOST', '127.0.0.1'),      // usually localhost, or mysql database server ip address
    'port' => env('DB_PORT', '3306'),           // default port 3306, or mention port in which it run on your server if it different
    'database' => env('DB_DATABASE', 'forge'),  // mention your mysql database name here  
    'username' => env('DB_USERNAME', 'forge'),  // mention your mysql database privileged user name 
    'password' => env('DB_PASSWORD', ''),       // password of your mysql database user
    'charset' => 'utf8mb4',                     // your mysql database charset  
    'collation' => 'utf8mb4_unicode_ci',        // your mysql database collation 
    'prefix' => '',
    'strict' => true,
    'engine' => null,
],
