CakePHP

To run apps based on the CakePHP framework using Unit:

1. Install Unit with a PHP 7.2+ language module.

2. Install CakePHP and create or deploy your app. Here, we use CakePHP’s basic template and Composer:

   Copy

   $ cd /path/to/ # Path where the application directory will be created; use a real path in your configuration 

   Copy

   $ composer create-project --prefer-dist cakephp/app:4.* app # Arbitrary app name; becomes the application directory name 

   This creates the app’s directory tree at /path/to/app/. Its webroot/ subdirectory contains both the root index.php and the static files; if your app requires additional .php scripts, also store them here.

3. Change ownership:

   Run the following command (as root) so Unit can access the application directory (If the application uses several directories, run the command for each one):

   Copy

   # chown -R unit:unit /path/to/app/ # User and group that Unit's router runs as by default 

   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.

4. Next, prepare the app configuration for Unit (use real values for share and root):

   Copy

   { "listeners": {  "*:80": {  "pass": "routes"  } }, "routes": [  {  "match": {  "uri": [  "*.php",  "*.php/*"  ],  "uri_comment": "The second element '*.php/*' handles all requests that explicitly target PHP scripts"  },  "action": {  "pass": "applications/cakephp/direct"  }  },  {  "action": {  "share": "/path/to/app/webroot$uri",  "share_comment": "Unconditionally serves remaining requests that target static files",  "fallback": {  "pass": "applications/cakephp/index",  "fallback_comment": "Serves any requests not served with the 'share' immediately above"  }  }  } ], "applications": {  "cakephp": {  "type": "php",  "targets": {  "direct": {  "root": "/path/to/app/webroot/",  "root_comment": "Path to the webroot/ directory; use a real path in your configuration"  },  "index": {  "root": "/path/to/app/webroot/",  "root_comment": "Path to the webroot/ directory; use a real path in your configuration",  "script": "index.php",  "script_comment": "All requests are handled by a single script"  }  }  } } }

   The difference between the pass targets is their usage of the script setting:

   • The direct target runs the .php script from the URI or defaults to index.php if the URI omits it.
   • The index target specifies the script that Unit runs for any URIs the target receives.

   For a detailed discussion, see Fire It Up in CakePHP docs.

5. Upload the updated configuration.

   Assuming the JSON above was added to config.json. Run the following command as root:

   Copy

   # curl -X PUT --data-binary @config.json --unix-socket \  /path/to/control.unit.sock \ # Path to Unit's control socket in your installation  http://localhost/config/ # Path to the config section in Unit's control API 

   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:
