NGINX Unit
v. 1.23.0

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. Run the following command for each directory containing app code or data so Unit can access it:

    # chown -R unit:unit /path/to/app/
    

    Note

    The unit:unit user-group pair is available only with official packages, Docker images, and some third-party repos. Otherwise, account names may differ; run the ps aux | grep unitd command to be sure.

    For further details, including permissions, see the security checklist.

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

    {
        "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",
                "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:
