Answer 1

Either your mongod is not running (check using "ps" command) or it is listening on some outside IP address and not on localhost. So first check the process list if 'mongod' is running. If yes, check with "netstat -nap" for the related port.

Of course you can start mongod on the console manually or even look into the mongod logfile (if there is one configured...depending on how you installed mongod).
