How to start node.js on port 80 on a linux server?

Question

When I try to start node on port 80, the error tells me that the port is in use. I imagine that\'s Apache.

What is the proper way to \"take over\" port 80, and keep

Answer 1

To take over port 80 when another process is listening on it, you must kill the process (or somehow tell it to stop listening). To ensure that Apache doesn't try to listen on port 80 again the next time it starts, you need to edit its configuration or prevent it from starting up.

To see which process is listening on port 80, run sudo netstat -ntap and look for the row with Local Address ending in port :80. The PID of the process (and the name) is in the far right column.
