mongodb忽略dbPath参数？

Question

I installed Mongodb latest (4.0) as a service on Windows 10
It seems like its ignoring the mongod.cfg file in the bin directory

C:\MongoDB4.0\bin\mongod.cfg
# Where and how to store data.
 storage:
     dbPath: C:\MongoDB4.0\data

The service will not start,
When I start it from CMD like:

c:\MongoDB4.0\bin>mongod.exe

This is its output: (see dbpath=c:\\data\\db)

Log:  [main] Automatically disabling TLS 1.0, to force-enable TLS 1.0 specify --sslDisabledProtocols 'none'
Log:  [initandlisten] MongoDB starting : pid=7104 port=27017 dbpath=c:\data\db\ 64-bit host=Win10-Pc
Log:  [initandlisten] targetMinOS: Windows 7/Windows Server 2008 R2
Log:  [initandlisten] db version v4.0.2
Log:  [initandlisten] git version: fc1573ba18aee42f97a3bb13b67af7d837826b47

I see that the service gets the configuration as a parameter

C:\\MongoDB4.0\\bin\\mongod.exe --config "C:\\MongoDB4.0\\bin\\mongod.cfg" --service

The --service option is used to create the initial service definition, and should generally not be required if you are using a MongoDB 4.0+ installer (which includes this step during installation).

To manage the MongoDB service from the command line you need to use net start MongoDB and net stop MongoDB .

c:\\MongoDB4.0\\bin>mongod.exe

If you run mongod.exe without any parameters the default values will be used (such as c:\\data\\db for the dbPath ). The server binary does not currently have a default location for a configuration file.

There's a relevant feature request to watch/upvote in the MongoDB issue tracker: SERVER-36150: Improved Default Config File Handling .
