This is a very short topic which talks about how to install Rails on Ubuntu 7.10.

Usually this process is simple (install the rails through GEM repository) however I had problem in the installation process and I will explain here how solved it.

First of all, you must have Ruby already installed. If you do not have Ruby installed, check this post out: http://www.jairrillo.com/blog/2008/01/05/getting-stated-in-ruby/

Next step is install Rails through GEM repository. Simply put the following command on the Linux shell:

sudo gem1.8 install rails -y 

Done! Rails is installed!!

Testing rails

Let’s create a simple rails project to test if the rails has been installed successfully.

First, create the rails project typing the following on the shell:

rails <project name>

A directory with the project name is going to be created.

Note: By default, the rails project is created using sqllite as database. If you want to use mysql instead, you can create a project calling the following parameter: –database=mysql

E.g. rails <project name> –database=mysql

Creating a controller

As mentioned before, I had problem when i tried to create a controller using the generate script.

Create a controller typing in the Linux shell the following command:

ruby script/generate controller test_controller

Hopefully the test_controller will be create without problem, like the image below:

ruby script/generate controller test_controller
      exists  app/controllers/
      exists  app/helpers/
      create  app/views/test_controller
      exists  test/functional/
      create  app/controllers/test_controller_controller.rb
      create  test/functional/test_controller_controller_test.rb
      create  app/helpers/test_controller_helper.rb

However you can get an error, like this:

usr/lib/ruby/gems/1.8/gems/rails-2.0.1/lib/initializer.rb:159:in
`require_frameworks': no such file to load -- openssl (RuntimeError)
        from /usr/lib/ruby/gems/1.8/gems/rails-2.0.1/lib/
initializer.rb:88:in `process'
        from /usr/lib/ruby/gems/1.8/gems/rails-2.0.1/lib/
initializer.rb:49:in `send'
        from /usr/lib/ruby/gems/1.8/gems/rails-2.0.1/lib/
initializer.rb:49:in `run'
        from /home/max/Desktop/rails/morpheus/config/environment.rb:13
        from /usr/local/lib/site_ruby/1.8/rubygems/custom_require.rb:
27:in `gem_original_require'
        from /usr/local/lib/site_ruby/1.8/rubygems/custom_require.rb:
27:in `require'
        from /usr/lib/ruby/gems/1.8/gems/rails-2.0.1/lib/commands/
generate.rb:1
        from /usr/local/lib/site_ruby/1.8/rubygems/custom_require.rb:
27:in `gem_original_require'
        from /usr/local/lib/site_ruby/1.8/rubygems/custom_require.rb:
27:in `require'
        from ./script/generate:3 

If you got the error above, you have to install the libopenssl-ruby1.8. Simply put the following line on the shell:

sudo apt-get install libopenssl-ruby1.8

After that, try to create the controller again. Hopefully it will work fine now

I hope this topic be useful for anyone.
