Server requirements

Note for users: This article has practical information for configuring your server. Be sure to share this article with your system administrator or hosting provider support desk and ask if your hosting solution already covers all or what’s needed to set it up.

Notes about configuration details: As a baseline reference, we set our technical requirements based on the APT packages of the current second-latest Ubuntu LTS release and its default configuration. We recommend using this second-latest Ubuntu LTS and build the stack from its default packages. Alternatively, install and configure a comparable setup.
