The only officially supported installs of Discourse are the [Docker](https://www.docker.io/) based beginner and advanced installs. We regret that we cannot support any other methods of installation. (Alternately, you can try the [unofficial Heroku install guide][heroku], the [unofficial Ubuntu install guide][ubuntu], the [BitNami Discourse Virtual Machine package][bitnami] or [Cloud66][cloud66].)
Hosting Rails applications is complicated. Even if you already have Postgres, Redis and Ruby installed on your server, you still need to worry about running and monitoring your Sidekiq and Rails processes. Additionally, our Docker install comes bundled with a web-based GUI that makes upgrading to new versions of Discourse as easy as clicking a button.
We take security very seriously at Discourse, and all our code is 100% open source and peer reviewed. Please read [our security guide](https://github.com/discourse/discourse/blob/master/docs/SECURITY.md) for an overview of security measures in Discourse.
