Hey @Venkata_Nagendra_45790

Do you have a running mongod? To check this run the following:

ps -ef | grep mongod

If you see the follow then you do not yet have a mongod process running and therefore will not be able to connect.

Like natac13 wrote you may have a mongod already listening to port 27017. But it may also be any other server. You can run ss -tnlup to find out which ports are taken.
