Ruby on Rails 3 Can't connect to local MySQL server through socket '/tmp/mysql.sock' on OSX

Question

I have a standard Rails3 environment, RVM 1.2.9, Rails 3.0.5, Ruby 1.9.2p180, MySQL2 Gem 0.2.7, mysql-5.5.10-osx10.6-x86_64

Error I get when running rake db:m

Answer 1

With my installation of MAMP on OSX the MySQL socket is located at /Applications/MAMP/tmp/mysql/mysql.sock. I used locate mysql.sock to find my MySQL socket location.

So my config/database.yml looks like:

development:
  adapter: mysql2
  host: localhost
  username: root
  password: xxxx
  database: xxxx
  socket: /Applications/MAMP/tmp/mysql/mysql.sock
