CodeIgniter

To run apps built with the CodeIgniter web framework using Unit:

1. Install Unit with a PHP language module.

2. Download CodeIgniter’s core files and build your application. Here, let’s use a basic app template, installing it at /path/to/app/.

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):

   console

   Copy

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

   # 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 CodeIgniter configuration for Unit:

   json

   Copy

   {
      "listeners": {
         "*:80": {
               "pass": "routes"
         }
      },
   
      "routes": [
         {
               "match": {
                  "uri": "!/index.php"
               },
               "_comment_match": "Denies access to index.php as a static file",
   
               "action": {
                  "share": "/path/to/app/public$uri",
                  "_comment_share": "Path to the application directory; use a real path in your configuration",
                  "fallback": {
                     "pass": "applications/codeigniter"
                  },
                  "_comment_fallback": "Serves any requests not served with the 'share' immediately above"
               }
         }
      ],
   
      "applications": {
         "codeigniter": {
               "type": "php",
               "root": "/path/to/app/public/",
               "_comment_root": "Path to the application directory; use a real path in your configuration",
               "script": "index.php"
         },
         "_comment_script": "All requests are served by a single script"
      }
   }

   {
      "listeners": {
         "*:80": {
               "pass": "routes"
         }
      },
   
      "routes": [
         {
               "match": {
                  "uri": "!/index.php"
               },
               "_comment_match": "Denies access to index.php as a static file",
   
               "action": {
                  "share": "/path/to/app/public$uri",
                  "_comment_share": "Path to the application directory; use a real path in your configuration",
                  "fallback": {
                     "pass": "applications/codeigniter"
                  },
                  "_comment_fallback": "Serves any requests not served with the 'share' immediately above"
               }
         }
      ],
   
      "applications": {
         "codeigniter": {
               "type": "php",
               "root": "/path/to/app/public/",
               "_comment_root": "Path to the application directory; use a real path in your configuration",
               "script": "index.php"
         },
         "_comment_script": "All requests are served by a single script"
      }
   }

5. Upload the updated configuration.

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

   console

   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
      

   # 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:
