Share This Article

Drupal is an open-source content management system for building websites.  The intent of this guide is to inform Hostwinds clients who are interested in Drupal’s system requirements prior to installing and running Drupal. This is one of the more common applications that many clients choose with a Shared or Business Hosting plan when getting started with Hostwinds. This guide is also relevant for Hostwinds Cloud, VPS and Dedicated server clients who are looking to configure their web hosting services to support a specific version of Drupal.
