I've been told by my professor to use linux to install nodejs, expressjs, and mongoDB. I've installed mongodb from the terminal, but when I try to execute the command "mongo", I get this:
MongoDB shell version: 2.6.10
connecting to: test

This answer by #CodeGench helped resolve my problems. Before doing it, I already tried uninstalling and reinstalling and all sorts of things which didn't work.
User This Command
sudo systemctl start mongod
Then
mongo
I have facing issues while running mongo commend after successful installation of mongoDB version 3.6.3.

Run into the same problem, my error was that I was this command:
sudo mongo service mongod start
Instead of this:
sudo service mongod start
Make sure you run the second one, hopefully that is your error source as well.

Open onemore terminal as admin and run mongod. After this you can start your app in main terminal.

What can I do?
looks like your mongod process is not running on port 27017. Make sure your mongod process is running maybe verify with linux command.
If you start mongod process and even then it's failing to connect with mongo command, it means it's failing to intialize, check out designated mongo log file for the reason
