MediaWiki§

To run the MediaWiki collaboration and documentation platform using Unit:

1. Install Unit with a PHP language module.

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

3. 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.

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

   {
       "listeners": {
           "*:80": {
               "pass": "routes"
           }
   
       },
   
       "routes": [
           {
               "match": {
                   "uri": [
                       "!/tests/qunit/*",
                       "/cache/*",
                       "/includes/*",
                       "/languages/*",
                       "/maintenance/*",
                       "/tests/*",
                       "/vendor/*"
                   ]
               },
   
               "action": {
                   "return": 404
               }
           },
           {
               "match": {
                   "uri": [
                       "/api.php*",
                       "/img_auth.php*",
                       "/index.php*",
                       "/load.php*",
                       "/mw-config/*.php",
                       "/opensearch_desc.php*",
                       "/profileinfo.php*",
                       "/rest.php*",
                       "/tests/qunit/*.php",
                       "/thumb.php*",
                       "/thumb_handler.php*"
                   ]
               },
   
               "action": {
                   "pass": "applications/mw/direct"
               }
           },
           {
               "match": {
                   "uri": [
                       "!*.php",
                       "!*.json",
                       "!*.htaccess",
                       "/extensions/*",
                       "/images/*",
                       "/resources/assets/*",
                       "/resources/lib/*",
                       "/resources/src/*",
                       "/skins/*"
                   ]
               },
   
               "action": {
                   "share": "/path/to/app$uri"
               }
           },
           {
               "action": {
                   "pass": "applications/mw/index"
               }
           }
       ],
   
       "applications": {
           "mw": {
               "type": "php",
               "targets": {
                   "direct": {
                       "root": "/path/to/app/"
                   },
   
                   "index": {
                       "root": "/path/to/app/",
                       "script": "index.php"
                   }
               }
           }
       }
   }
   

   Note

   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 w omits it.
   • The index target specifies the script that Unit runs for any URIs the target receives.

5. 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.

6. Browse to http://localhost/mw-config/index.php and set MediaWiki up using the settings noted earlier:

   

   Download the newly generated LocalSettings.php file and place it appropriately:

   $ chmod 600 LocalSettings.php
   # chown unit:unit LocalSettings.php
   # mv LocalSettings.php /path/to/app/
   

7. After installation, add a match condition to the first step to disable access to the mw-config/ directory:

   # curl -X POST -d '"/mw-config/*"'  \
          --unix-socket /path/to/control.unit.sock  \
          http://localhost/config/routes/mediawiki/0/match/uri/
   
         {
             "success": "Reconfiguration done."
         }
   

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