Here is what I tried:

Answer 1

For anyone who's having this problem on a remote server rather than the localhost, try enabling external interfaces:

• Go to the configuration file (ex. /etc/mongodb.conf)
• Find bind_ip=127.0.0.1
• Comment out that line with a # at the front
• Restart mongod

Answer 2

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

Answer 3

For the newer versions(4.x) of MongoDb, you can try:

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

sudo systemctl daemon-reload

sudo systemctl start mongod

Answer 4

First make sure you have installed mongodb using sudo apt install mongodb

Answer 5

Try following commands :

sudo service mongod start
sudo service mongod status

db.py

import pymongo
from pymongo import MongoClient
#mongo client is connected
client = MongoClient()
db     = client['db']

Answer 6

If you're trying to connect from a server (other than your localhost), try checking if your mongo installation is complete : you should have: * /var/lib/mongodb file * /var/log/mongodb file * mongodb.service as service ( check by starting the service sudo service mongodb start )

If any of those fails, try reinstalling mongo ( Failed to start mongod.service: Unit mongod.service not found )

This solved my problem. Cheers
