To configure Nginx for a Laravel application located within a subfolder, a location block is required to handle requests to that specific subfolder. This configuration ensures that Nginx correctly serves the Laravel application from its public directory within the subfolder.

Here is a basic Nginx configuration example for a Laravel application in a subfolder named subapp:

server {

    listen 80;

    server_name your_domain.com; # Replace with your domain

    root /var/www/html; # Root for your main website or other content

    index index.html index.htm index.php;

    # Configuration for the Laravel subfolder

    location /subapp {

        alias /var/www/subapp/public; # Path to your Laravel application's public directory

        try_files $uri $uri/ @subapp; # Handle requests within the subapp

        location ~ \.php$ {

            fastcgi_pass unix:/var/run/php/php8.1-fpm.sock; # Adjust PHP-FPM socket path

            fastcgi_param SCRIPT_FILENAME $request_filename;

            include fastcgi_params;

        }

    }

    # Named location for Laravel's index.php within the subapp

    location @subapp {

        rewrite /subapp/(.*)$ /subapp/index.php?/$1 last;

    }

    # Default PHP handling for other parts of your website (if any)

    location ~ \.php$ {

        fastcgi_pass unix:/var/run/php/php8.1-fpm.sock; # Adjust PHP-FPM socket path

        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;

        include fastcgi_params;

    }

    # Deny access to .env files and other sensitive directories

    location ~ /\.env {

        deny all;

    }

    location ~ /\.ht {

        deny all;

    }

}

Explanation:

• location /subapp block:

  • alias /var/www/subapp/public;: This directive tells Nginx to serve files for requests to /subapp from the specified path, which is the public directory of your Laravel application.
  • try_files $uri $uri/ @subapp;: This attempts to serve the requested URI, then a directory with that URI, and finally, if neither is found, it uses the named location @subapp.
• location ~ \.php$ inside /subapp:

  • This nested location block handles PHP requests specifically for the Laravel application in the subfolder.
  • fastcgi_pass: Specifies the address of your PHP-FPM service. Adjust the socket path to match your PHP version.
  • fastcgi_param SCRIPT_FILENAME $request_filename;: This is crucial for subfolder setups as it ensures PHP-FPM correctly identifies the script to execute within the aliased directory.
• location @subapp block:

  • rewrite /subapp/(.*)$ /subapp/index.php?/$1 last;: This named location is used by try_files to rewrite requests to the Laravel index.php file, passing the original request path as a query string.
