Cannot connect to mongodb errno:61 Connection refused

Question

I recently installed mongodb-2.6.0 with Homebrew. After successfully installed, I tried to connect using the mongo command. I am receiving the following errors

Answer 1

It can happen when the mongodb service is not running on the mac. To start it, I tried

brew services start mongodb

and it worked.

Edit: According to the discussion on this PR on homebrew: https://github.com/Homebrew/homebrew/issues/30628

brew services is deprecated, I looked around on SO and found these answers now answer the question: What is the correct way to start a mongod service on linux / OS X?
