The Simplest App - Default Rails page on a shared host

In this chapter, we'll make probably the most simplest app on a shared host. It just displays the "default Rails page".

We'll do the minimal to make the app:

  1. In ~/rails_app/ directory, issue "rails new firstapp" to make an app.
  2. make a subdomain named as firstapp.
  3. Delete ~/public_html/firstapp.
  4. In ~/public_html/, make symlink: "ln -s ~rails_apps/firstapp/public firstapp".

Actually, that's it. We made an RoR app!
