Answer 1

To solve this exception you already have a process running in the port 27017 which is used by mongodb. So either you need to stop the process in that port or try with a different port number.

You should try:  mongod --port 27018

You can change the port number of your choice.

Tried this but didn't work for me, what other option do I have?

Answer 2

The first thing that you have to do is destroy the previous mongod instance and start the new one. To remove the previous mongod instance, first search for a file of tasks running on your machine by typing:

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

Search for mongod COMMAND and its PID and type the following command:

sudo kill <mongo_command_pid>

Now just start your mongod instance by typing the following:

mongod
