I’ve just followed a great walk-though on getting Rails up and running on Ubuntu. I now have Eclipse (with the RadRails plugin), mysql, apache, Ruby and Rails all working really well.

A lot of what I post here doubles as a journal of sorts, insuring I don’t lose any of these juicy nuggets when I need them again, so I’m going to do a big ol’ copy and paste. Hopefully that’s cool with the author…

Part I: Installation

Prepare the system for the installation

• Check /etc/apt/sources.list - make sure you have access to the ‘universe’ packages by uncommenting them:

deb <a href="http://us.archive.ubuntu.com/ubuntu">http://us.archive.ubuntu.com/ubuntu</a> dapper universe
deb-src <a href="http://us.archive.ubuntu.com/ubuntu">http://us.archive.ubuntu.com/ubuntu </a>dapper universe

• Refresh apt packages to make sure you get the most up-to-date stuff:

sudo apt-get update

Install Ruby related packages

• Install Ruby essentials: ruby, irb, rdoc, ri

sudo apt-get install ruby rdoc ri

• Install gems: download, unpack, install

go to <a href="http://docs.rubygems.org/">http://docs.rubygems.org/</a>
download rubygems-0.8.11.tgz (or the latest version)  tar -xzvf rubygems-0.8.11.tgz
cd rubygems-0.8.11/
sudo ruby setup.rb

MySQL installation and configuration

• Install MySQL:

sudo apt-get install mysql-server

• Install ruby MySQL bindings

sudo apt-get install libmysql-ruby

Install Rails

sudo gem install rails --include-dependencies

Part II: Configuration

Setup the DB

• Add an user, create a test database and grant acces for the user

mysqladmin -u root create test_development

mysql -u root

Into the db shell, write the following commands:

create user 'batman'@'localhost' identified by 'robin'
grant all on test_development.* to 'batman'@'localhost';

Don’t forget to replace the username/password (unless you happen to be Batman of course - in this case i suggest to use a different password since this can be guessed easily by social engineers Create and test the rails app

• generate the app files

Lets denote your working directory (the root directory where your future rails project s will reside rails_projects).

cd rails_projects
rails test

• edit config/database.yml

cd rails_projects/test
vim config/database.yml

• It should look like this:

development:
adapter: mysql
database: test_development
username: batman
password: robin
host: localhost

• generate a dummy model

ruby script/generate model Dummy

• edit the migration file

vim db/migrate/001_create_dummies.rb

class CreateDummies < ActiveRecord::Migration
def   self.up
create_table :dummies do |t|
t.column :foo,    :string
t.column :bar,    :string
end
end
 
def self.down
drop_table :dummies
end
end

• run the migration

rake db:migrate

• generate a simple maintenance app

ruby script/generate scaffold Dummy Admin

• start the server

ruby script/server
