Unable To Manipulate MongoDB Due To Unproperly Closed Terminal?

I met a problem while I was learning MongoDB. Here are my steps eliciting the problem:

1. I start MongoDB service: mongod.

2. In my terminal, at the MongoDB service window, I carelessly close it without using ctrl + c to kill the service process.

3. Now, I cannot manipulate MongoDB service AT ALL…

Solution

There might be several different ways to solve the problem in different systems. Mine is MacOS, so here is my solution:

1. Open a new window of terminal, type mongo, to enter MongoDB, as the process is still working, so I’m able to login.

2. type use admin to get the root permission.

3. type db.shutdownServer().

Now the service has been closed successfully. I can simply type mongod to start it again, and manipulate by using the normal window. Next time, I will be carefull when trying to close a terminal window. Attatching this solution in case the same condition happens in future.
