Problem analysis

In fact, this problem is not complicated, just because your mongodb is not started. Just start it.

Problem-solving

Enter the bin directory of mongodb (enter the bin directory of mongodb you installed)

Input command (port number can be specified)

mongod –logpath “E:\professional_software\mongodb\data\log\mongodb.log” –dbpath “E:\professional_software\mongodb\data\db” –logappend

or

mongod –logpath “E:\professional_software\mongodb\data\log\mongodb.log” –dbpath “E:\professional_software\mongodb\data\db” –logappend –port 8888

In this way, the startup is successful and the next step is ready. Open another command prompt and enter mongo.
