Overview

Note: This example is brief! There are quite some settings that should still be added. For examples, see: https://github.com/mainframe98/MediaWiki-Family-Configuration-Example

• Place the three files above in the folder where MediaWiki is installed.
• Create a folder named dblists, and create a file named all.dblist. Its contents should be:

mediawiki|Media Wiki|en
datawiki|Data Wiki|en
enwiki|Atheistpedia|en
bnwiki|Atheistpedia in Bengali|bn
hiwiki|Atheistpedia in Hindi|hi

• This example also contains a redirect on line 64 of LocalSettings.php.
  • There is an example file I created here: https://github.com/mainframe98/MediaWiki-Family-Configuration-Example/blob/master/WikiNotFound404.php
• File uploads are redirected to the images folder, to a specific folder for each wiki, based on their database name (i.e. if uploads are enabled on enwiki, uploads will go to $IP/images/enwiki)
• The same applies for the cache folder, enwiki cache will go in $IP/cache/enwiki
• Logos are, unless overridden, located in $IP/images/DATABASENAME_logo.png, so for enwiki this would be $IP/images/enwiki_logo.png.
