Ruby on Rails, Part 1: Installation

Installing Ruby on Rails in Ubuntu 11.10 involves basically these things:

1. Install Ruby:
   • sudo apt-get install ruby
   • After this, you should be able to use "irb", interactive ruby.
2. Install RubyGems:
   • sudo apt-get install rubygems
   • This will make it easier to work with ruby, um, gems.
3. Install Rails:
   • gem install rails
   • The version of rails I've installed (3.1) seems to assume sqlite will also be installed, so:
   • sudo apt-get install libsqlite3-dev
   • Then, rails server wouldn't run because it "could not find javascript runtime", so:
   • sudo apt-get install nodejs

Because I wanted to use mysql, git, and vim:

1. Install MySQL:
   • sudo apt-get install mysql-server
   • sudo apt-get install libmysqlclient-dev
2. Install git:
   • sudo apt-get install git
3. Install the rails extension for vim:
   • sudo apt-get install vim-rails

After all this, I was able to run initialize a new project named foo:

rails new foo

And create a database in mysql:

$ mysql -u root
mysql> create database test;
mysql> show databases;
mysql> exit
