How to Install Laravel In A Subdomain?

8 minutes read

To install Laravel in a subdomain, follow these steps:

  1. Make sure you have a subdomain set up on your hosting provider. This can usually be done through the control panel or domain management tools.
  2. Download and install Laravel on your server. You can do this by running the composer create-project command in your server's command line interface.
  3. Once Laravel is installed, navigate to the project's root directory and configure the subdomain's document root to point to the "public" folder of the Laravel installation. This can be done through the hosting provider's control panel or by editing the virtual host configuration file.
  4. Update the .env file in the Laravel installation to include the subdomain's URL in the APP_URL variable. For example, if your subdomain is "subdomain.example.com", set APP_URL=http://subdomain.example.com.
  5. Test the installation by accessing the subdomain in a web browser. If everything is configured correctly, you should see the Laravel welcome page.


That's it! You have successfully installed Laravel in a subdomain. Now you can develop and deploy your Laravel application in the subdomain without any issues.

How to handle routing in Laravel subdomains?

To handle routing in Laravel subdomains, you need to follow these steps:

  1. Configure the subdomain: In the Apache or Nginx configuration file, set up a wildcard subdomain that points to your Laravel project directory. For example, you can set up "*.example.com" or "subdomain.example.com" to point to the public directory of your Laravel project.
  2. Define the subdomain route: In your Laravel routes file (usually routes/web.php), define the subdomain route using the domain method of the Route facade, specifying the desired subdomain as a parameter. For example:
1
2
3
Route::domain('subdomain.example.com')->group(function () {
    // Subdomain specific routes
});


  1. Define the subdomain-specific routes: Within the group defined for your subdomain, define the routes that should be accessible only through the subdomain. For example:
1
2
3
4
Route::domain('subdomain.example.com')->group(function () {
    Route::get('/', 'SubdomainController@index');
    Route::get('/about', 'SubdomainController@about');
});


  1. Access the subdomain routes: Now you can access the subdomain-specific routes by visiting the defined subdomain URL in your browser.


Note: Be aware that when testing locally, modifying the hosts file on your machine may be necessary to map the desired subdomain to your local server.


Additionally, it's important to check your Laravel version and ensure it supports subdomain routing.


How to configure Laravel's environment variables for a subdomain?

To configure Laravel's environment variables for a subdomain, you can follow these steps:

  1. Open the .env file in the root directory of your Laravel project. This file contains all the environment variables for your application.
  2. Configure the necessary environment variables for your subdomain. For example, if your subdomain requires a database connection, you may need to set the following variables: DB_CONNECTION=subdomain DB_HOST=subdomain_host DB_PORT=subdomain_port DB_DATABASE=subdomain_database DB_USERNAME=subdomain_username DB_PASSWORD=subdomain_password Replace subdomain with the appropriate values for your subdomain.
  3. Save the .env file.
  4. In your Laravel project, open the config/database.php file.
  5. Locate the connections array in the database.php file and add a new array entry for your subdomain's database connection. For example: 'subdomain' => [ 'driver' => env('DB_CONNECTION', 'mysql'), 'host' => env('DB_HOST', '127.0.0.1'), 'port' => env('DB_PORT', '3306'), 'database' => env('DB_DATABASE', 'forge'), 'username' => env('DB_USERNAME', 'forge'), 'password' => env('DB_PASSWORD', ''), ], Ensure that the 'driver', 'host', 'port', 'database', 'username', and 'password' values match the environment variable names you defined in the .env file.
  6. Save the database.php file.


Now you can use the subdomain's environment variables in your Laravel application by accessing them using the env() helper function or the config() function.


For example, you can use env('DB_CONNECTION') or config('database.connections.subdomain') to access the subdomain's database connection configuration.


What is the purpose of a subdomain?

The purpose of a subdomain is to create separate websites or web pages within a larger domain. It allows the website owner to organize and structure their content hierarchy, create different sections or categories, or provide specific functionalities while utilizing the same main domain.


Subdomains are commonly used for various purposes, such as:

  1. Organization: Large websites can use subdomains to categorize their content or services. For example, a blog may have separate subdomains for different topics like news.example.com, food.example.com, or sports.example.com.
  2. Multilingual sites: Subdomains are often employed to provide versions of a website in different languages, such as en.example.com for English, fr.example.com for French, etc.
  3. Services or functionalities: Websites may use subdomains to offer specific services or functionalities separate from the main website. For instance, mail.example.com for email services or store.example.com for an online store.
  4. Campaigns or events: Subdomains can be used for specific campaigns, events, or temporary content. This approach allows businesses to maintain a distinct online presence without affecting their main website. For example, blackfriday.example.com or summer-sale.example.com.
  5. Testing or development: Subdomains are often used for testing new features or changes before deploying them to the main website. This allows developers to work independently without affecting the live site.


Overall, subdomains provide flexibility in managing website content, structuring information, and delivering different services, all while being part of the same root domain.
