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

You can access port 80 once you stop the service currently using it.

In your case, follow these steps:

1) Use systemctl to stop apache2:

sudo systemctl stop apache2

2) Check apache2 status:

sudo systemctl status apache2

Or just by entering http://localhost in your browser. If you get an error, you are good to go.

ERR_CONNECTION_REFUSED

3) Now start your NodeJS server on port 80.

4) You can access your server at http://localhost

UPDATE

If you are seeing errors on your console, try node preceding with sudo For eg. sudo node server.js

Here are the errors
