I suspect you have another instance of mongod running.

Run ps -aef | grep [m]ongod and share the output.

OK! Thank you ! This is the output.

You have to terminate this current instance first. You may visit for more information on how to terminate mongod.

Hi @lin_32912,

I hope you found the response form @steevej-1495 helpful. As I can see, you have completed the lab so I’m closing this thread. Please feel free to create another thread if you have any other issue.
