On CiviHosting, it’s very easy. First step is to install MediaWiki. See our page How to Install MediaWiki for details on that.
Second step is to run these commands from the command line:
mkdir -p ./extensions/SemanticMediaWiki chmod ugo+rw ./extensions/SemanticMediaWiki composer require mediawiki/semantic-media-wiki "3.0.0" --update-no-dev composer require mediawiki/semantic-result-formats "3.0.0" composer update --no-dev
Third step is to add
enableSemantics( 'example.org' );
to your LocalSettings.php and change that “example.org” to your URL. Then just run this:
php71.cli maintenance/update.php
to finish.
That’s it. 🙂
