Use the command:

Ps-aux | grep Tomcat

A tomcat process with no 8080 ports found.

Use command: NETSTAT–APN

View all process and port usage. Discover the following list of processes, where the last column is pid/program name

8080 ports were found to be occupied by the Java process with PID 9658.

Further use of the command: Ps-aux | grep Java, or directly: Ps-aux | grep PID View

You can clearly know that the 8080 port is a program occupied! Then decide if you want to kill with the KILL command!
