We found that the reason for this error was the dbpath variable in /etc/mongodb. conf. Previously, 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.
To open up the MongoDB shell, run the mongo command from your server prompt. By default, the mongo command opens a shell connected to a locally-installed MongoDB instance running on port 27017 . Try running the mongo command with no additional parameters: mongo.
On your system, if you have used MongoDB in the past it must have been with a different dbPath or you have since deleted that path. I suggest you either specify a different path or create the /data/db folder for MongoDB to store its data.
Assuming that you installed MongoDB Server with default options, especially the installation folder as C:\Program Files\MongoDB\Server\4.0 . Inside this folder, you have the bin directory containing mongod.exe. To start MongoDB Server in Windows, start Mongo Daemon (mongod.exe) using the following command:
If you start mongod with no dbPath parameter it will default to /data/db. On your system, if you have used MongoDB in the past it must have been with a different dbPath or you have since deleted that path. I suggest you either specify a different path or create the /data/db folder for MongoDB to store its data.
From the messages logged to the console, you can observe that: Mongo Server is started as a process with process id (pid): 11716. Mongo Server is listening at the port number: 27107. You can see at the end of logs [initandlisten] waiting for connections on port 27017. Mongo Server is using the database present at the location C:\data\db\.
I had the same issue and I managed to start mongod following those steps
1) mkdir data
2) cd data
3) mongod -dbpath .

Use this command, it works fine:
sudo mongod --config /etc/mongod.conf --fork
Try using sudo mongo to connect

Please make sure if port 27017 is already opened and didn't used by any application. You can check it with netstat command
