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:
