NGINX Unit
v. 1.32.1

Catalyst§

To run apps based on the Catalyst 5.9+ framework using Unit:

  1. Install Unit with a Perl language module.

  2. Install Catalyst’s core files.

  3. Create a Catalyst app. Here, let’s store it at /path/to/app/:

    $ cd /path/to/
    $ catalyst.pl app
    $ cd app
    $ perl Makefile.PL
    

    Make sure the app’s .psgi file includes the lib/ directory:

    use lib 'lib';
    use app;
    
  4. Run the following command so Unit can access the application directory:

    # 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.

  5. Next, prepare the Catalyst configuration for Unit (use real values for script and working_directory):

    {
        "listeners": {
            "*:80": {
                "pass": "applications/catalyst"
            }
        },
    
        "applications": {
            "catalyst": {
                "type": "perl",
                "working_directory": "/path/to/app/",
                "script": "/path/to/app/app.psgi"
            }
        }
    }
    
  6. 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 -h or see Startup and Shutdown for details.

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