Answer 2

I understand the question is with regards to Ubuntu.

But if you're getting the same error on a Mac and don't want $ sudo mongod running on a separate tab, you can do the following to fix the connection error, if you have Homebrew -

brew services start mongodb

Based on the answer from this thread - Cannot connect to mongodb errno:61 Connection refused

Answer 3

In my case the problem was caused due to an apparent lost of permission over mongodb.lock file. I could solve the problem changing the permission with the following command :

sudo chown mongodb:mongodb /var/lib/mongodb/mongodb.lock

There follows my investigation:

Answer 4

Follow this simple steps; (Works on MAC OS too)

1. Open terminal and run sudo mongod

2. Open a new terminal tab(Don't close step 1 tab) and run sudo mongo

That's all

Answer 5

In my case the error was due to missing /data/db folder which the mongodb uses to store your data. Please type this command $sudo mongod in your terminal. If the error message is something like :

missing data/db folder error

Simply create the folder and you are good to go.

Answer 6

Probably you don't have space in your hard drive. Check it by typing in the promt df -h

Please note that mongo might fail even with 3gb available in the corresponding partition. For details, you might want to check the log: cat /var/log/mongodb/mongod.log
