Removing MediaWiki entirely can be accomplished in two steps: removing the directory where MediaWiki was installed, and dropping the MediaWiki database from MySQL or Postgres.

Löschen der MediaWiki-Dateien

Um das Wiki selbst zu deinstallieren, lösche einfach das Verzeichnis, welches die Dateien des Wikis enthält. Zum Beispiel, wenn du MediaWiki in /var/www/mediawiki-xyz installiert hast, würdest du folgendes tun:

rm -rf /var/www/mediawiki-xyz
Warnung Warnung: Depending how you configured your wiki, uploaded files and images may be stored within a sub-directory of the installation directory. If you don't want to delete the uploaded content, make sure you move this to a safe place before deleting!

In this case you will need to manually delete each of the wiki's tables. See the instructions for your database software for more details about how to do this.

Alternatively, you can use a DB administrative tool, such as PHPMyAdmin, to perform the same action.


To remove the Postgres database holding your wiki, run the following command:

dropdb wikidb

or connect to the database as a user with the correct permissions and issue:
