Install Laravel 5.4 using Composer
Video Tutorial How to Install Lumen 5.3
The Lumen framework has a few system requirements. Of course, all of these requirements are satisfied by the Laravel Homestead virtual machine, so it's highly recommended that you use Homestead as your local Lumen development environment.
However, if you are not using Homestead, you will need to make sure your server meets the following requirements:
- PHP >= 5.6.4
- OpenSSL PHP Extension
- PDO PHP Extension
- Mbstring PHP Extension
ConfigurationAll of the configuration options for the Lumen framework are stored in the .env file. Once Lumen is installed, you should also configure your local environment.
Application KeyThe next thing you should do after installing Lumen is set your application key to a random string. Typically, this string should be 32 characters long. The key can be set in the .env environment file. If you have not renamed the .env.example file to .env, you should do that now. If the application key is not set, your user encrypted data will not be secure!
