We used DokuWiki to create and host our own internal Wiki on the latest version of Ubuntu Server (22.04.1 at the time of this writing). How cool is this? We’ll, it’s actually more than just ‘cool’ and can make for an invaluable tool used to centrally store crucial information while making it conveniently accessible to you and your teams.

If you’re new to DokuWiki and unfamiliar with PHP, installation and setup can be a daunting task. But not to worry because today we are going to fly you through installation step by step and as a bonus, show you the basics to get your Wiki up and running in no time.

From the horses mouth ->

DokuWiki is a simple to use and highly versatile Open Source wiki software that doesn’t require a database. It is loved by users for its clean and readable syntax. The ease of maintenance, backup and integration makes it an administrator’s favorite. Built in access controls and authentication connectors make DokuWiki especially useful in the enterprise context and the large number of plugins contributed by its vibrant community allow for a broad range of use cases beyond a traditional wiki.
