Trying to connect Sequel Pro to localhost

I’m building a new rails app that’s defaulted to mysql. I ran:

rails new project_board -d mysql

I’m running ruby 2.0, rails 4.0 and mysql 5.6.12

I installed mysql via homebrew

My database.yml file looks like this:

adapter: mysql2
encoding: utf8
database: project_board_development
pool: 5
username: root
host: localhost

But when I try to connect to Sequel Pro through this window:

I get the following error:

Unable to connect via the socket, or the request timed out.
Double-check that the socket path is correct and that you have the necessary privileges, and that the server is running.
MySQL said: Can’t connect to local MySQL server through socket ‘/tmp/mysql.sock’ (2)

I’ve also tried connecting via the standard method through and it isn’t working either. Just curious if anyone has had this issue.

Sorry, it’s not letting my image display. It’s the socket tab, with name: localhost and username: root.

Never mind. I’m an idiot.

What was the problem?

I never started the mysql server in the terminal:

mysql.server start
