You can kill the previous mongod instance and start the new one.

To kill the previous mongod instance, first search for a list of tasks running on your machine by typing,

sudo lsof -iTCP -sTCP:LISTEN -n -P 

Search for mongod COMMAND and its PID and type,

sudo kill <mongo_command_pid> 

Now start your mongod instance by typing,

mongod 

You can see MongoDB running successfully.
