How to find and kill a process using a specific port

14

I need to free up port 8000 but something is already using it. How can I find what process is using it and kill it?

Not confirmed since it was written, 9 months, 1 week ago This still works

Find process using port

# Using lsof
sudo lsof -i :8000

# Using netstat
sudo netstat -tlnp | grep :8000

# Using ss
sudo ss -tlnp | grep :8000

Kill the process

# Kill by PID
kill -9 PID_NUMBER

# Kill all processes on port (one-liner)
sudo fuser -k 8000/tcp
