Answer 1

Failed to start mongod.service: Unit mongod.service not found

If you are following the official doc and are coming across with the error above that means mongod.service is not enabled yet on you machine (I am talking about Ubuntu 16.04). You need to do that using following command

sudo systemctl enable mongod.service

Now you can start mongodb using the following command

sudo service mongod start
