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
and now port 8080 is free.
