Do you remember my guide on how to install Answer on your Synology NAS that I posted some time ago? The installation instructions I proposed some time ago used SQLite as database. Today I’m proposing instructions for Answer to use the stable and secure MySQL as database. Answer is an open-source knowledge-based community software. You can use it to quickly build your Q&A community for product technical support, customer support, user communication, and more. In this step by step guide I will show you how to install Answer with MySQL on your Synology NAS using Docker & Portainer.

💡Note: This guide works perfectly with the latest Answer v1.4.0 release.
