To run the Redmine project management system using Unit:

  1. Install Unit with a Ruby language module.

  2. Install and configure Redmine’s prerequisites.

  3. Install Redmine’s core files. Here, we install it at /path/to/app/; use a real path in your configuration.

  4. Run the following command so Unit can access the application directory:

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


    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 Redmine configuration for Unit (use a real value for working_directory):

        "listeners": {
            "*:80": {
                "pass": "applications/redmine"
        "applications": {
            "redmine": {
                "type": "ruby",
                "working_directory": "/path/to/app/",
                "script": "",
                "environment": {
                    "RAILS_ENV": "production"
  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/


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

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