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

On my machine mysqld service stopped that's why it was giving me the same problem.

1:- Go to terminal and type

sudo service mysqld restart

This will restart the mysqld service and create a new sock file on the required location.
