I have a droplet on Digital Ocean that I'm using to host projects and learn about different technology. I already have a couple of things running using Apache2 and mod_wsgi running a Flask app. I'm interested in trying out some other things, specifically a Django app with Nginx and Gunicorn.
The various tutorials I've looked at all recommend starting with a fresh Ubuntu server, but I don't want to wipe my server; I'd like to keep hosting my existing projects.
Is it possible to set up all of this stuff on a single server without causing problems? If so, I don't need a walkthrough, because I'll probably learn more figuring it out as I go but, if it isn't possible, I'd rather not throw away hours of time trying to make it work when it never will.
