You need to first start mongo server at port 27017.
You can do it by executing following command:
mongod --port 27017 --dbpath [database_path]

Connection error while installing mongodb on Fedora 28

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

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

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
