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:
