I have been trying to install Mongodb but it keeps failing midway. When the download is complete, installation fails with a connection error:
MongoDB shell version v3.6.3
connecting to: mongodb://127.0.0.1:27017
2018-08-17T12:26:33.340+0200 W NETWORK [thread1] Failed to connect to 127.0.0.1:27017, in(checking socket for error after poll), reason: Connection refused

What I've tried:
1. Changing the port:
mongo --port 4332
but it doesn't connect still:
MongoDB shell version v3.6.3
connecting to: mongodb://127.0.0.1:4332/

Reinstalling the DB shows up as complete but I still can't start it. Check out the screenshot
Checking for any config files in /etc/mongo* or /var/lib/: there is none.
Note: There's no mongod service available too.
the installation seem to have worked, but the mongod was not started.
MongoDB need two element :
the "mongo" shell utility, who is used to connect to the database direcly
the "mongod" service, who is the true database programs.
to start the mongod, simply use a cmd and use the "mongod" command. this command may fail if :
the port is already used (default is 27017)
the dbpath directory was not created (default is /data/db)
Fedora repository do not install both at the same time.
the shell is in the repository under the "mongodb" name
the server is under the name "mongodb-server"
so to install both, you need to do
dnf install mongodb mongodb-server
and you can then start the mongod service with
sudo service mongod start

I am running a mean app, but when I go to run 'mongo', I get the following error:

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
Then
mongo

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
