All of these requirements are satisfied by the [Laravel Homestead](/docs/{{version}}/homestead) virtual machine, so it's highly recommended that you use Homestead as your local Laravel development environment. However, if you are not using Homestead, you will need to make sure your server meets the following requirements: <div class="content-list" markdown="1"> - PHP >= 7.2.0 - BCMath PHP Extension - Ctype PHP Extension - JSON PHP Extension - Mbstring PHP Extension - OpenSSL PHP Extension - PDO PHP Extension - Tokenizer PHP Extension - XML PHP Extension </div> <a name="installing-laravel"></a> ### Installing Laravel Laravel utilizes [Composer](https://getcomposer.org) to manage its dependencies. So, before using Laravel, make sure you have Composer installed on your machine. #### Via Laravel Installer First, download the Laravel installer using Composer: composer global require laravel/installer Make sure to place Composer's system-wide vendor bin directory in your `$PATH` so the laravel executable can be located by your system. This directory exists in different locations based on your operating system; however, some common locations include: <div class="content-list" markdown="1"> - macOS and GNU / Linux Distributions: `$HOME/.config/composer/vendor/bin` - Windows: `%USERPROFILE%\AppData\Roaming\Composer\vendor\bin` </div> Once installed, the `laravel new` command will create a fresh Laravel installation in the directory you specify. For instance, `laravel new blog` will create a directory named `blog` containing a fresh Laravel installation with all of Laravel's dependencies already installed: laravel new blog #### Via Composer Create-Project Alternatively, you may also install Laravel by issuing the Composer `create-project` command in your terminal: composer create-project --prefer-dist laravel/laravel blog #### Local Development Server If you have PHP installed locally and you would like to use PHP's built-in development server to serve your application, you may use the `serve` Artisan command. This command will start a development server at `http://localhost:8000`: php artisan serve More robust local development options are available via [Homestead](/docs/{{version}}/homestead) and [Valet](/docs/{{version}}/valet). <a name="configuration"></a> ### Configuration #### Public Directory After installing Laravel, you should configure your web server's document / web root to be the `public` directory. The `index.php` in this directory serves as the front controller for all HTTP requests entering your application. #### Configuration Files All of the configuration files for the Laravel framework are stored in the `config` directory. Each option is documented, so feel free to look through the files and get familiar with the options available to you. #### Directory Permissions After installing Laravel, you may need to configure some permissions. Directories within the `storage` and the `bootstrap/cache` directories should be writable by your web server or Laravel will not run. If you are using the [Homestead](/docs/{{version}}/homestead) virtual machine, these permissions should already be set. #### Application Key The next thing you should do after installing Laravel is set your application key to a random string. If you installed Laravel via Composer or the Laravel installer, this key has already been set for you by the `php artisan key:generate` command. 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 sessions and other encrypted data will not be secure!** #### Additional Configuration Laravel needs almost no other configuration out of the box. You are free to get started developing! However, you may wish to review the `config/app.php` file and its documentation. It contains several options such as `timezone` and `locale` that you may wish to change according to your application. You may also want to configure a few additional components of Laravel, such as: <div class="content-list" markdown="1"> - [Cache](/docs/{{version}}/cache#configuration) - [Database](/docs/{{version}}/database#configuration) - [Session](/docs/{{version}}/session#configuration) </div> <a name="web-server-configuration"></a> ## Web Server Configuration <a name="directory-configuration"></a> ### Directory Configuration Laravel should always be served out of the root of the "web directory" configured for your web server. You should not attempt to serve a Laravel application out of a sub-directory of the "web directory". Attempting to do so could expose sensitive files present within your application. <a name="pretty-urls"></a> ### Pretty URLs #### Apache Laravel includes a `public/.htaccess` file that is used to provide URLs without the `index.php` front controller in the path. Before serving Laravel with Apache, be sure to enable the `mod_rewrite` module so the `.htaccess` file will be honored by the server. If the `.htaccess` file that ships with Laravel does not work with your Apache installation, try this alternative: Options +FollowSymLinks -Indexes RewriteEngine On RewriteCond %{HTTP:Authorization} . RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}] RewriteCond %{REQUEST_FILENAME} !-d RewriteCond %{REQUEST_FILENAME} !-f RewriteRule ^ index.php [L] #### Nginx If you are using Nginx, the following directive in your site configuration will direct all requests to the `index.php` front controller: location / { try_files $uri $uri/ /index.php?$query_string; } When using [Homestead](/docs/{{version}}/homestead) or [Valet](/docs/{{version}}/valet), pretty URLs will be automatically configured.
