I followed this post, http://blog.teamtreehouse.com/installing-ruby-rails-and-mysql-on-os-x-lion .
I have been learning Ruby and Rails for a month, so I am quite familiar with Ruby. I also know some parts of Rails due to the understandings acquired by following several tutorials.

I already successfully finished brew install mysql
and checked mysql -u root
