macos - 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 which do not allow me to connect:

Failed to connect to 127.0.0.1:27017, reason: errno:61 Connection refused

Error: couldn't connect to server 127.0.0.1:27017 (127.0.0.1), connection attempt failed at src/mongo/shell/mongo.js:146

exception: connect failed

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?
