I'll comment below.

Bill,
First, I really appreciate your help. At the risk of sounding
naïve, in response to Dheeraj’s post that “You need to add it to the
gemfile and run the bundle command.” How do I do that? I guess this is
where I need to be more specific about where I left off. Ok, the tutorial
that I mentioned here:
http://blog.sudobits.com/2012/05/02/how-to-install-ruby-on-rails-in-ubuntu-12-04-lts/
uses the Webrick server. For some reason, when I started that server and
then tried to view the page using port 3000, it did not connect.
Were you trying to connect from within your virtualbox environment, or from
the host OS? Try looking at your Webrick-hosted sites from the same OS that
you launched them under -- that's the normal use-case for those sorts of
self-hosted apps. It's meant to be a window into your dev site, just a
quick-and-dirty hack to get you to a click-test of the app.
Yes, I was trying from the host OS. I do have KDE installed in Linux so I
can browse to the Webrick link.
Therefore, I had my VirtualBox setup with Ubuntu and using Apache2 on port
8080, which I could get to from my host OS. I wasn’t seeing that test app
described at the above link, until I went into the folder
http://localhost:8080/test_app/
Of course, now, for some reason, I cannot get into any of the apps
that I just installed hours ago. I get Not Found at the test_app link
that I included just above. I can go to the http://localhost:8080/ uri
and see some web content that was put there. However, the test_app that
worked fine just a little while ago, is not working now. Had it been
working I would have said that the last problem to address is creating an
application with mysql support.
Not sure what this all means, but I would still try to see the site from
within the linux environment, if that's where it is running (that is, if it
was started with `rails server` from within the folder in a terminal).
I wonder why I cannot get an app created in RoR with support for mysql?
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. Passenger on Linux is a very patient and
instructive installer script, so much so that I have not yet failed to get
it running on a bare VPS, despite my home-school approach to Linux admin.
Can you expand on this? What will Passenger do?
It is frustrating that my problem is now apparently related to my
Linux installation on my system and I cannot address the other issues of
moving on to learning RoR.
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. Unlike in that
tutorial, I couldn’t go to just http://localhost:8080 or localhost:3000, I
had to add the directory in my browsers address bar, then I think I had to
go into public.
2) How are you installing the mysql2 gem? Are you using Bundler? In the
above referenced tutorial, I didn’t need mysql. However, when I added
that to the command line:
rails new simple_cms –d mysql
I got the message: “An error occurred while installing mysql2 (0.3.11),
and Bundler cannot continue. Make sure that ‘gem install mysqsl2 –v
‘0.3.11’` succeeds before bundling. So, I then enter
gem install mysql2 –v ‘0.3.11’
Then I try my install again... when asked to continue and over-write, I
say Y. Then I get the same error.
What is curious is that if I include the ` after the gem install mysql –v
‘0.3.11’ it gives me a different prompt.
3) Is the gem specified in the Gemfile? Were you able to rake db:migrate
or is that where you're having your problem?
I don’t know what the latter means. I can look at the Gemfile and it has
this in it:
source :rubygems
gemspec
Your gemfile should have quite a bit more than that inside it, at least on a
bare Rails app. Here's one now:
source 'https://rubygems.org'
gem 'rails', '3.2.7'
# Bundle edge Rails instead:
# gem 'rails', :git => 'git://github.com/rails/rails.git'
gem 'sqlite3'
# Gems used only for assets and not required
# in production environments by default.
group :assets do
gem 'sass-rails', '~> 3.2.3'
gem 'coffee-rails', '~> 3.2.1'
# See https://github.com/sstephenson/execjs#readme for more supported
runtimes
# gem 'therubyracer', :platforms => :ruby
gem 'uglifier', '>= 1.0.3'
end
gem 'jquery-rails'
# To use ActiveModel has_secure_password
# gem 'bcrypt-ruby', '~> 3.0.0'
# To use Jbuilder templates for JSON
# gem 'jbuilder'
# Use unicorn as the app server
# gem 'unicorn'
# Deploy with Capistrano
# gem 'capistrano'
# To use debugger
# gem 'debugger'
IF that file exists at the base of your rails root, and you cd into that
folder and type bundle install, you should see a lot of terminal whizz by,
and your app should suddenly have everything it needs to start up properly.
How do I get a Gemfile that is like that? My installation process didn't
seem to work.
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. See if you can get to a
bare virtual host, just a folder with index.html in it. IF that works, then
go up a level and make sure that passenger is properly installed, and you've
configured a new virtual host for your Rails app. Don't try to share a vhost
with another app.
I need to learn more. Like how to get a bare virtual host... do you mean
reinstall apache somehow? Create a new install of Ubuntu in the VirtualBox?
I do have root access to a dedicated server but it uses CentOS and so that
is different and I'm only just now learning Linux.
Thanks,
Bruce

Anyway, I keep going in circles. I get a message saying that I need to
install gem msyql2 which I do and it reports back with no error and so I
try again to install the app with the rails command and I get the same
error.
I took a quick look at that tutorial, and if that's all you did you should
be getting the index.html file that Rails installs (the tutorial left out
the part where it tells you that you have to delete it). If you did that,
then you're into the app itself and your problem description doesn't say
much about what you did in addition to the tutorial.
So.... need a little more info. How are you installing the mysql2 gem?
Are you using Bundler? Is the gem specified in the Gemfile? Were you
able to rake db:migrate or is that where you're having your problem?
Best regards,
Bill
