Any way discourse can be installed?
Discourse requires Ruby, Postgres and Redis. You can definitely install it on your own server but you can not install it on servers launched via Cloudways. Our servers are for PHP based applications only.
You can refer to this guide here on how to install it on your own server: https://github.com/discourse/discourse/
If you feel it is a geeky stuff, you can hire a developer on Fiverr at as low as 5dollar for installation of discourse forum
