Kill what ever is running on port 8080

I am trying to run a GAE app on localhost:8080, but it was apparently occupied, even after shutting down and restarting my computer. I ran sudo lsof -i :8080. Lo and behold there is something sill running with PID 66. What can I do to kill that process and free up 8080 again?

1. Find out what Process ID (pid) is using the required port (e.g port 5434).

   ps aux | grep 5434

2. Kill that process:

   kill -9 <pid>

2

lsof -i @localhost:8080

kill -9 <<PID>>

Turns out it's just kill -9 PID, you might need sudo. Found the answer on maclife.com in the article Terminal 101: Track and Kill Processes.

Merging answers from above in one line: kill $(lsof -t -i:8080)

lsof -t returns the PID and passes that to kill.

Use the following command to find the process ID of the process running on the desired port:

$ netstat -ano | findstr :8080

The result will be displayed as:

$ netstat -ano | findstr :5000 TCP 0.0.0.0:5000 0.0.0.0:0 LISTENING 18024

Here, 18024 is the PID or Process ID.

Then use the following command to kill the process on the post 8080:

$ taskkill /PID 18024 /F

or:

$ taskkill //PID 18024 //F

Result will be displayed as:

$ taskkill //PID 18024 //F
SUCCESS: The process with PID 18024 has been terminated.
