NGINX Unit
v. 1.21.0

Symfony§

To run apps built with the Symfony framework using Unit:

  1. Install Unit with a PHP 7.2.5+ language module.

  2. Next, install Symfony and create or deploy your app. Here, we use Symfony’s reference app:

    $ cd /path/to/
    $ symfony new --demo app
    

    This creates the app’s directory tree at /path/to/app/. Its public/ subdirectory contains both the root index.php and the static files; if your app requires additional .php scripts, also store them here.

  3. Set installation path permissions to secure access, for example:

    # chown -R app_user:app_group /path/to/app/
    

    Update the placeholders above with actual values, noting them for later use in Unit configuration.

  4. Next, prepare the configuration for Unit (use real values for share, root, user, and group):

    {
        "listeners": {
            "*:80": {
                "pass": "routes/symfony"
            }
        },
    
        "routes": {
            "symfony": [
                {
                    "match": {
                        "uri": [
                            "*.php",
                            "*.php/*"
                        ]
                    },
    
                    "action": {
                        "pass": "applications/symfony/direct"
                    }
                },
                {
                    "action": {
                        "share": "/path/to/app/public/",
                        "fallback": {
                            "pass": "applications/symfony/index"
                        }
                    }
                }
            ]
        },
    
        "applications": {
            "symfony": {
                "type": "php",
                "user": "app_user",
                "group": "app_group",
                "targets": {
                    "direct": {
                        "root": "/path/to/app/public/"
                    },
    
                    "index": {
                        "root": "/path/to/app/public/",
                        "script": "index.php"
                    }
                }
            }
        }
    }
    

    Note

    The difference between the pass targets is their usage of the script setting:

    • The direct target runs the .php script from the URI or defaults to index.php if the URI omits it.
    • The index target specifies the script that Unit runs for any URIs the target receives.

    For a detailed discussion, see Configuring a Web Server in Symfony docs.

  5. Upload the updated configuration. Assuming the JSON above was added to config.json:

    # curl -X PUT --data-binary @config.json --unix-socket \
           /path/to/control.unit.sock http://localhost/config/
    

    Note

    The control socket path may vary; run unitd --help or see Startup and Shutdown for details.

    After a successful update, your project and apps should be available on the listener’s IP address and port:
