Self-host a GDPR-compliant club wiki with MediaWiki or DokuWiki under Virtualmin – document club knowledge and minutes centrally and for free

Why a wiki for your club?

As a club, you collect valuable knowledge: minutes, statutes, contact details, project plans – all of this should be stored in a structured and secure manner. A wiki is ideal for this. However, if you use an external wiki service, you often don't know where your data is stored and whether it is processed in compliance with the GDPR. With a self-hosted wiki under Virtualmin, you retain full control over your data and meet the requirements of the General Data Protection Regulation (GDPR).

GDPR-compliant hosting: what does it mean?

The GDPR requires that personal data be processed only in countries that offer an adequate level of data protection. If you host your wiki on a server in Germany or the EU, you are on the safe side. In addition, as the data controller, you must ensure that only authorized persons have access and that data is transmitted encrypted. With your own server, you can determine all of this yourself.

MediaWiki or DokuWiki – what fits better?

Both systems are open source and free. MediaWiki is the system behind Wikipedia and offers countless extensions. It is powerful but also more complex to set up. DokuWiki, on the other hand, is slimmer and does not require a database because it uses files. This makes it easier to manage and back up. For a club that wants to manage minutes and documents, DokuWiki is often the quicker solution. However, if you plan a large wiki with many users and complex workflows, MediaWiki is the better choice.

Virtualmin: Your hosting control panel for GDPR-compliant self-hosting

Virtualmin is a powerful web hosting control panel with which you can manage multiple domains and applications on one server. It offers a graphical interface for managing databases, email accounts, and files – ideal if you are not an expert in server administration. With Virtualmin, you can set up your own domain for your wiki in a few steps and activate SSL certificates to encrypt data transmission.

Step by step: How to host your wiki with Virtualmin

The prerequisite is a server with Virtualmin. You can rent a virtual server from a provider that gives you root access. Then it starts:

• Register domain: Choose a suitable domain for your wiki, e.g., wiki.yourclub.de. You can register it here with us.
• Create domain in Virtualmin: In Virtualmin, create a new virtual server instance and assign the domain.
• Set up SSL: Activate Let's Encrypt SSL for an encrypted connection.
• Create database (only for MediaWiki): Create a MySQL database via Virtualmin.
• Install wiki software: Download MediaWiki or DokuWiki and upload the files to the web directory of your domain. Alternatively, you can use an installation script via Virtualmin.
• Complete configuration: Follow the installation wizard in the browser and enter the database details (for MediaWiki) or the admin credentials.
• Manage access rights: Set up user accounts and assign different permissions, e.g., only for board members.

Data protection in the wiki: What you should consider

Even if you host yourself, you must comply with the GDPR. This includes:

• Rights management: Determine who can see and edit which content. This ensures that sensitive data does not fall into the wrong hands.
• Encryption: Always use HTTPS (SSL certificate). This is easy to implement with Let's Encrypt in Virtualmin.
• Backups: Create regular backups of your wiki data. This protects you against data loss.
• Record of processing activities: Document which personal data you store in your wiki and for what purpose.
• Deletion concept: Define how long you retain data and how you delete it when it is no longer needed.

Conclusion: Centrally and for free to a club wiki

With a self-hosted wiki under Virtualmin, you not only meet the GDPR requirements but also save ongoing costs for external services.
