How to Find and Kill a Process that is Using a Particular Port in Ubuntu


I had a problem with tomcat, it says that port 8080 is already in use so I can not use it …

What I did ?

1- Find what application/process is using the pro, type:

sudo netstat -lpn |grep :8080

and press Enter.

You will get an output similar to this one

tcp6       0      0 :::8080                 :::*                    LISTEN      6782/java

2- I have got the process Id, which is 6782, now this is the process that is using port 8080.

3- Kill the process, type:kill 6782

kill 6782

and now port 8080 is free.
