How to kill a process running on particular port in Linux?

Question

I tried to close the tomcat using `./shutdown.sh` from tomcat `/bin` directory. But found that the server was not closed properly. And thus I was unable to restartMy tomcat is running on port `8080`. I want to kill the tomcat process running on `8080`. I first want to have the list of processes running on a specific port (8080) in order to select which process to kill.

Answer 1

I would recommend shutting down all tomcat processes. Because it's a server, it's likely spinning up multiple processes that respawn whenever one is killed. You can try the following command to kill all tomcat processes:

killall -9 tomcat

The -9 flag forces the process to terminate immediately.
