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
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

exception: connect failed


What I've tried:
1. Changing the port:
mongo --port 4332
but it doesn't connect still:  

MongoDB shell version v3.6.3

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.
As it turns out, Fedora treats mongo and mongod as two separate packages. While on most distributions you can install both services in a single bundle, on Fedora you have to install them separately.
sudo dnf install mongodb mongodb-server
Then you can start the service with mongod.
