How do i stop the rails sever?

I run this command to start my server

rails s -b 10.x.x.x

then I got this error

[1013] * Puma version: 5.2.2 (ruby 2.6.3-p62) ("Fettisdagsbulle")
[1013] *  Min threads: 2
[1013] *  Max threads: 2

Address already in use - bind(2) for "10.x.x.x" port 3000 (Errno::EADDRINUSE)

How do I stop this current running server 10.x.x.x:3000?

>Solution :

There are several utilities to get the PID of a proccess listening on a port.

lsof -i :3000

Will get you the PID and then you can kill it with kill [PID] or force it with kill -9 [PID]
