Please copy and paste the exact rails new … command you typed into terminal when you created your test app. There are tons of flags you can use to set up rails with various databases. By default, it will use SQLite3, because that just works most places. If you pass -d mysql to the new command, you will get a mysql connector. But note that you don't have to do this at the beginning of your project. You can create a default (SQLite) application, then transfer it to MySQL or PostgreSQL or anything else that's supported, later in the project life-cycle by changing a few lines of your gemfile and database.yml files. > > If you have Apache running inside virtualbox, and you can see a test site > (the classic It Works! page) at :8080 from your host OS, then you need to set > up passenger inside Linux, configure each virtual host where you want to run > Rails, and it should just work.

What will Passenger do? Passenger is one of the ways to serve Rails applications. Think of it as mod_php but for Rails. It's an Apache module that understands the structure of a Rails application and how to pass Web requests from Apache into Rails.

I would take the patient advice of many others on this list, and please put down the Lynda tutorial. Pick up the http://railstutorial.org path instead. This is a FREE course that teaches you how to go from nothing to a working, tested Rails app hosted on Heroku (which is also free) and will give you the leg up you need without immersing you in the minutia of installation hell where you seem to be circling. You will still want to get a working local install of Rails, which will include being able to browse your test site (hosted out of Webrick) locally at http://localhost:3000 But that is really not as hard as your combination of aged tutorial and lack of experience in Linux is giving you. There are even instructions in railstutorial that will show you how to get Rails installed directly under Windows, although I would urge you to charge on and get it to work in your Linux environment instead. >> 1) test_app from the tutorial: >> http://blog.sudobits.com/2012/05/02/how-to-install-ruby-on-rails-in-ubuntu-12-04-lts/ >> **was** working fine with apache2, not with Webrick.

Please post the rails new command that you typed (at its most basic, this will be `rails new mynewapp` and it will be followed by a bunch of feedback from the rails command, culminating in a working Rails app). Also post the output of rails -v in your terminal. >> >> I know it is somewhat off topic, but I have to somehow figure out why the >> apps I created previously, php and the RoR app (without the msyql support) >> are not now accessible from a browser. > > You've probably borked your Apache install somewhat.

If you started with a distribution of Linux that included Apache already configured, you may have a working copy of Apache. Try launching Apache in your terminal: sudo apachectl configtest sudo apachectl start (substitute apache2ctl if apachectl doesn't work -- depends on the distro) If configtest doesn't report any errors, start may tell you Apache is already running. If not, it will start it. When Apache is running, then try going to http://localhost in your Linux browser, and see what you see there. You should see the default host, which in many Ubuntu versions is a white page with the words It Works! really big at the top. If that works, then move on to installing Passenger, which will get you a connection between Apache and Rails. The Passenger installer will probably tell you to install a half-dozen packages, and it will tell you explicitly how to do this. Like I said, it's very patient.
