How do I kill a process running on port 3000?

To do that, you can use lsof . If you want a way to remember lsof, it is that it means 'list of'. Now there will be nothing running on port :3000. This will also work for any other port you're having issues with, i.e. :8080, :1337, or any other number.

Why is port already in use?

How do I kill all processes on a port?

The fuser command combined with the -k (kill) option will end all associated processes that are listening on a TCP or UDP port. Simply provide the port number and type (TCP or UDP) in the fuser command. You can use the lsof command to verify that processes are no longer running on the target port.

How do I stop a process on port 8080?

Why is port 3000 default?

3000 is a somewhat arbitrary port number chosen because it allows you to experiment with express without root access (elevated privilege). Ports 80 and 443 are the default HTTP and HTTPS ports but they require elevated privilege in most environments.

Why does my printer always say port in use?

These errors are typically caused by incorrect printer port settings, for example when a computer specifies an incorrect printer port number or type in the printer driver. To fix this type of problem, configure the printer port settings on the computer.

What is port 27217 already in use?

Edit: Port 27217 is used for MongoDB. To address the problem, you may also check if there are other applications/processes occupying this port. If port 27217 is already occupied by some other applications/processes, the MongoDB cannot be initialed, and thus it will lead to the failure of the Controller.
