When I try to use the cmd prompt, I get the following error:

I had the same problem.

Try deleting mongod.lock file from Mongo data directory.



For example, my is "C: \ Program Files \ MongoDB \ Data \ mongod.lock" and after deleting the file, start the MongoDB service and it works like a spell.

If anyone else comes across this issue, just read your log files and you should be able to find the problem, for me after trying to install it inside the wamp directory when starting the MongoDB service it gave me the same error message, I went to the logs and found out, what I am missing is a directory inside my data directory which is called db

as soon as I created this directory the service works fine.

MongoDB uses a default folder to store its files. The default location on Windows C:\data\db

.

The folder may not exist. In this case, just create it or change the default Mongo service location using the flag --dbpath command-line

.

Removing mongod.lock didn't work for me, repair didn't help either. In my case it was due to corruption of one of the database, I moved all the dbs to a different directory and then copied them one by one and restarted the mongodb service to figure out which db file was corrupted. This is definitely a MongoDb bug

So I just had the same issue running on Windows 10. The reason MongoDB would not start was because the data and log path was not set correctly. This has already been pointed out, but my solution is different. Take a look at C:\Program Files\MongoDB\Server\4.0\bin

(or where your mongoDB is installed). There is a configuration file called mongod.cfg

. Check that

storage:
  dbPath:

and

systemLog:
  path:

Set to whatever you want. In my case, these were% MONGODBPATH% environment variables or similar that were not set on Windows. By default, the log and data should point to C:\Program Files\MongoDB\Server\4.0\data

and C:\Program Files\MongoDB\Server\4.0\log\mongod.log

respectively.

I had the same error message. Try looking for mongodb log files and see the latest entries. My problem was clearly outlined there, missing directory:

2019-01-29T16: 59: 44.424 + 0100 i STORAGE [initandlisten] Exception in initAndListen: NonExistentPath: data directory C: \ wamp64 \ bin \ mongodb \ mongodb-win32-x86_64-2008plus-ssl-3.6.10 \ data \ db not found., terminated

For on-site demand: There was a "npm:" in last line of mongodb configuration file which is located in the installation folder bin\mongod.cfg


I commented out this line and started the service and it works like a charm.
I concluded by running mongodb service command from windows command prompt (cmd) and got an error.

ran the following on the command line:
C:\Program Files\MongoDB\Server\4.2\bin\mongod.exe --config "C:\Program Files\MongoDB\Server\4.2\bin\mongod.cfg" --service
