Kill process by used port Ubuntu

Kill process by used port Ubuntu

Using fuser

The best way to kill a port is 

fuser -k 8080/tcp

Using kill

Find what application/process is using the port: 

sudo netstat -lpn |grep :8080

You will get an output similar to this one 

tcp6       0      0 :::8080                 :::*                    LISTEN      21994/java

You got the process Id, which is 21994, now this is the process that is using port 8080

Kill the process

kill 21994
