python - Pymongo keeps refusing the connection at 27017

Question

I am trying to run a simple connection to pymongo but it keeps returning that the connection was refused

Here is what I tried:

>>>from pymongo import Connection
>>>connection = Connection('localhost',27017)

here is what I get

Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/local/lib/python2.7/dist-packages/pymongo-2.0.1_-py2.7-linux i686.egg/pymongo/connection.py", line 348, in __init__
 self.__find_node()
File "/usr/local/lib/python2.7/dist-packages/pymongo-2.0.1_-py2.7-linux- i686.egg/pymongo/connection.py", line 627, in __find_node
  raise AutoReconnect(', '.join(errors))
pymongo.errors.AutoReconnect: could not connect to localhost:27017: [Errno 111]     Connection refused

How do I fix this?

Answer 1

Removing mongod.lock inside /var/lib/mongodb

sudo rm /var/lib/mongodb/mongod.lock

And then restarting the service should do it. For example, in my Ubuntu installation, restarting the server is something like this:

sudo service mongodb start
