Question

I’m trying to get Mongo running.

I installed the package manager Homebrew

I then used the commands located on the Mongo site:

$ brew update
$ brew install mongodb

This appeared to install correctly.
I typed mongo in a new terminal window and got the following error:

MongoDB shell version: 2.0.1
connecting to: test
Thu Dec 15 09:37:25 Error: couldn't connect to server 127.0.0.1 shell/mongo.js:84
exception: connect failed

So I then followed the instructions found on here

Ran mongod and this is the result:

mongod --help for help and startup options

Notice there was an exception with "initAndListen" then it shutdown.

What am I doing wrong? How can I fix this installation and get Mongo up and running?

Answer 1

This is the problem:

15 09:38:49 [initandlisten] exception in initAndListen: 10296 dbpath (/data/db/) does not exist, terminating

Create the path /data/db on your system and it will work.
