Thread:Project:Support desk/How to install MediaWiki Version 1.23.5?/reply (3)

That's not correct. Mediawiki can create both the user and the database. When you follow the installation script, there's one step where you can provide privileged mysql account credentials and also credentials for the database user MediaWiki will use, so it can create the database and create the user with the necessary privileges. If you don't provide the privileged user, MediaWiki will assume the database and the user already exist.
