Cannot start MongoDB as a service

Question

I have been developing for MongoDB for some months now and would like to install it as a service on my Windows 7 Enterprise machine. The following is the command that I hav

Answer 1

To others who may have the same problem on Windows Server 2012:

I have just got the same problem with Mongo 3.0.3 on Windows Server 2012. I am not a system admin so I don't know what they have changed for sc.exe. I have to use

sc.exe create MongoDB binPath= "C:\mongodb\bin\mongod.exe --service --config=C:\mongodb\mongod.cfg" DisplayName= "MongoDB" start= "auto"

This is without the \"\" for both binary and config file paths comparing to the one on their website.

Answer 2

I had made few changes in the Config start-up file, which caused this issue. When I looked in the "mongo.log" file, it said

"Cannot start server. Detected data files in E:\Mongo\data\db created by storage engine 'wiredTiger'. The configured storage engine is 'mmapv1'., terminating"

Resetting the storage engine back to 'wiredTiger' resolved the issue for me. Hope this helps others.

Answer 3

I ran this command:

C:\MongoDB\Server\3.4\bin>net start MongoDB

And got this message:

The service is not responding to the control function. More help is available by typing NET HELPMSG 2186.

After some trials and errors, I noticed when following the tutorial it asked me to name my file mongod.conf but the command was trying to refer to mongod.cfg.

As soon as I corrected that name and re-run the commands,

C:\MongoDB\Server\3.4\bin>sc.exe delete MongoDB
[SC] DeleteService SUCCESS

C:\MongoDB\Server\3.4\bin>sc.exe create MongoDB binPath= "\"C:\MongoDB\Server\3.4\bin\mongod.exe\" --service --config=\"C:\MongoDB\Server\3.4\mongod.cfg\"" DisplayName= "MongoDB" start= "auto"
[SC] CreateService SUCCESS

C:\MongoDB\Server\3.4\bin>net start MongoDB
The MongoDB service is starting....
The MongoDB service was started successfully.

The service started running fine.

Answer 4

Have your checked you logging to see the real problem?

I suggest extracting the Mongo installation to c:\mongodb.

Create the c:\mongodb\logs and the c:\mongodb\data\db directories.

Then browse the the c:\mongodb\bin directory and run the following to remove the service (if you've installed it!):

mongod --remove

Then install the service, specifying the log and data directories:

mongod --logpath c:\mongodb\logs\mongo.log --dbpath c:\mongodb\data\db --directoryperdb --install

Then if there is a problem starting the service you should see the reason in the specified log file.

Answer 5

Following works with MongoDB 3.6.0

Make sure you have these folders:

• C:\mongodb\data
• C:\mongodb\data\db

Then all you need are these commands:

• mongod --directoryperdb -dbpath C:\mongodb\data\db --logpath C:\mongodb\log\mongo.log --logappend --service --install
• net start MongoDB
• mongo

Answer 6

Remember to create the database before starting the service

Now your database is prepared and you can start the service using

C:\>net start MongoDB
The MongoDB service is starting.
The MongoDB service was started successfully.
