Make a test server not accessible to any networks

Question

I need to make a test lamp server that runs php files on localhost for anyone with direct access to the computer but isn't accessible from any networks. How does one do this?

Answer 1

In Apache conf (httpd.conf) you can configure it so it only listens on your local ip (127.0.0.1). I can't remember where in the conf, but I think it's the same place you configure the port, i.e. it's normally something like:

*:80

Change it to:

127.0.0.1:80

Answer 2

If you are using Apache, you can simply make it listen only to 127.0.0.1 using the following directive:

 Listen 127.0.0.1:80
