Mongo failed to start

I am running a mean app, but when I go to run 'mongo', I get the following error:
MongoDB shell version v4.0.0
connecting to: mongodb://127.0.0.1:27017

I am sure I am missing something simple here.
mongo is the Mongo shell. It connects to the Mongo daemon, mongod, which isn't running - hence the error.
At the command-line: sudo mongod
Enter your password, and the daemon should start. Now, when you run mongo it should start up ok.

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

Getting error with mongo commend after install mongodb version 3.6.3

I have facing issues while running mongo commend after successful installation of mongoDB version 3.6.3.
I have run mongo commend and got the following error
MongoDB shell version v3.6.3

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.

Failing to connect to mongodb

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

Whats wrong with my Mongo query?

I've recently set a path in my vi .bash_profile to my mongo commands. I know this works because it was working yesterday.
However when I do it now I get this error:
AMAC02MX3APF8J3:~ james.flan$ mongo

Here is the content in my vi .bash_profile:
alias mongod="mongod --dbpath /Users/ryan.garrett/Documents/Software/MongoDB/data"
export PATH="/Users/ryan.garrett/Documents/Software/MongoDB/bin:$PATH"
Can someone please tell me how to connect to the server?
Check your /etc/hosts for localhost entry and also make sure that mongod is listening to all interfaces, you can check by netstat -an|grep mongo.
