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

Question

My problem is similar to other inputs and suggestions on this site, but none has helped me. After installing MongoDB, has not started because the database is not running.

First try to run mongo and I answered this:

Mac-Pro-de-User: ~ user $ mongo 
MongoDB shell version: 2.6.4 
connecting to: test 
2014-10-28T10: 47: 08713-0700 warning: Failed to connect to 127.0.0.1:27017, reason: errno: 61 Connection refused

exception: connect failed 

Then try to check the mongod and I answered this:

Mac-Pro-de-User: ~ user $ mongod 
mongod --help for help and startup options

Then try again to connect and spend some time, and again says the same:

2014-10-28T11: 05: 34589-0700 [clientcursormon] connections: 0

And so on. If you can help would greatly appreciate it.

PS: There is already the / data / db with 777 permissions, and I'm using OSX Mavericks 10.9.5

Answer 1

Just try this command.

sudo chown mongodb /tmp/mongodb-27017.sock

And

sudo service mongod restart

Answer 2

Fixed!

The reason was the dbpath variable in /etc/mongodb.conf. Previously, I was using mongodb 1.8, where the default value for dbpath was /data/db. The upstart job mongodb(which comes with mongodb-10gen package) invokes the mongod with --config /etc/mongodb.conf option.

As a solution, I only had to change the owner of the /data/db directory recursively.

Like this: Go to "/data" location in the terminal and then type

sudo chown -R <username>:foldername

For example:

sudo chown -R raja db/
