Setting up Ruby on Rails Database Connection using SQLite (version 2 and 3) on Ubuntu Feisty Fawn
SQLite is good for development and testing, and depending on your needs production even. By default Typo uses SQLite for production. The greatest advantage is that it's light. (like duh), and very easy to deploy.
Note: There are two versions of SQLite, version 2 and 3. They produce databases which are incompatible with each other.
Version 2
Enter into the Terminal:
sudo apt-get install ruby1.8-dev libsqlite0-dev
sudo gem install sqlite-ruby
If you see this, select 1 (enter it in).
Select which gem to install for your platform (i486-linux)
1. sqlite-ruby 2.2.3 (ruby)
2. sqlite-ruby 2.2.3 (mswin32)
3. sqlite-ruby 2.2.2 (ruby)
4. sqlite-ruby 2.2.2 (mswin32)
5. Skip this gem
6. Cancel installation

Edit the file [image16x16:file] RAILS_ROOT/config/database.yml. For now we are using the [image16x16:database] development environment. The environment you are deploying your database should look like so.
development: adapter: sqlite dbfile: db/development.sql
Version 3
Enter into the Terminal:
sudo apt-get install ruby1.8-dev libsqlite3-dev
sudo gem install sqlite3-ruby
If you see this, select 1 (enter it in).
Select which gem to install for your platform (i486-linux)
1. sqlite3-ruby 1.2.1 (ruby)
2. sqlite3-ruby 1.2.1 (mswin32)
3. sqlite3-ruby 1.2.0 (mswin32)
4. sqlite3-ruby 1.2.0 (ruby)
5. Skip this gem
6. Cancel installation

Edit the file
RAILS_ROOT/config/database.yml. For now we are using the
development environment. The environment you are deploying your database should look like so.
development: adapter: sqlite3 dbfile: db/development.sql
Conclusion
There you have it, your database is now set up!
