How to force the database name when installing Laravel?

To force a custom database name when installing Laravel, you can follow these steps:

1. Create a new Laravel project: If you haven't already created a new Laravel project, you can do so using Composer or Laravel Sail. For example:

   composer create-project --prefer-dist laravel/laravel my-project
   

2. Configure the .env file: After creating the project, you need to configure the .env file to use your custom database name. Open the .env file in the root of your project and update the DB_DATABASE value to your desired database name. For example:

   DB_DATABASE=my_custom_database
   

3. Update the config/database.php file: Laravel uses the config/database.php file to manage database connections. Ensure that the database key in the mysql connection array is set to env('DB_DATABASE', 'laravel'). This ensures that the value from the .env file is used.

   'mysql' => [
       'driver' => 'mysql',
       'host' => env('DB_HOST', '127.0.0.1'),
       'port' => env('DB_PORT', '3306'),
       'database' => env('DB_DATABASE', 'laravel'),
       'username' => env('DB_USERNAME', 'root'),
       'password' => env('DB_PASSWORD', ''),
       'unix_socket' => env('DB_SOCKET', ''),
       'charset' => 'utf8mb4',
       'collation' => 'utf8mb4_unicode_ci',
       'prefix' => '',
       'strict' => true,
       'engine' => null,
   ],
   

4. Create the database: Ensure that the database with the custom name exists. You can create it using a database management tool like phpMyAdmin, or via the command line. For example, using MySQL:

   mysql -u root -p
   CREATE DATABASE my_custom_database;
   

5. Run the migrations: Finally, run the Laravel migrations to set up the database schema.

   php artisan migrate
   

By following these steps, you can configure Laravel to use a custom database name during installation and setup.
