NGINX Unit
v. 1.28.0

Roundcube§

To run the Roundcube webmail platform using Unit:

  1. Install Unit with a PHP language module.

  2. Install and configure Roundcube’s prerequisites.

  3. Install Roundcube’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/
    

    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 Roundcube configuration for Unit (use real values for share and root):

    {
        "listeners": {
            "*:80": {
                "pass": "routes"
            }
        },
    
        "routes": [
            {
                "match": {
                    "uri": [
                        "*.php",
                        "*/"
                    ]
                },
    
                "action": {
                    "pass": "applications/roundcube"
                }
            },
            {
                "action": {
                    "share": "/path/to/app$uri"
                }
            }
        ],
    
        "applications": {
            "roundcube": {
                "type": "php",
                "root": "/path/to/app/"
            }
        }
    
  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, browse to http://localhost/installer/ and set up your Roundcube installation:

  7. After installation, switch share and root to the public_html/ subdirectory to protect sensitive data:

    # curl -X PUT -d '"/path/to/app/public_html$uri"' --unix-socket \
          /path/to/control.unit.sock http://localhost/config/routes/1/action/share
    # curl -X PUT -d '"/path/to/app/public_html/"' --unix-socket \
          /path/to/control.unit.sock http://localhost/config/applications/roundcube/root
    

    Thus, Roundcube should be available on the listener’s IP address and port:
