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 (as root) 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. Run the following command as root:

   # 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
   

   Run the following commands (as root) to set the correct ownership:

   # 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. Run the following command (as root):

   # 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:
