Answer 1

This directory /data/db is not present in your machine.

Create that one or pass --dbpath option while starting the mongo daemon.

{"error":"NonExistentPath: Data directory /data/db not found. Create the missing directory or specify another path using (1) the --dbpath command line option, or (2) by adding the 'storage.dbPath' option in the configuration file."}}
