localhost on WAMP returns 404, changing port numbers doesn't help

Question

When I try and access my WAMP server over a connection to localhost through Firefox I get a 404 error.

I checked the firewall and changed it to off. Then I changed the listening port from 80 to 81 but I didn't change the port for localhost (port 80). The error changed and it says:

#2005 - Unknown MySQL server host 'localhost:81' (11001)

When I ping port 80 it says "this port is not used" so I'm really confused.

Answer 1

It looks like a configuration problem. MySQL does not run on port 80 or port 81.

Can you give some more details about your install. Where did you get the software? What OS are you installing it on? Is there any other software installed prior to the "WAMP" install?

Answer 2

1) The default MySQL port is 3306. Port 80 is the HTTP port, and is the port used by Apache.

2) A 404 error is not caused by firewalls. 404 HTTP status code means that the server (Apache) received the request but can't find the asked for file (bad url or missing file).

A firewall issue would simply block the request and you would get nothing back (no status codes).

3) Apache does not respond to "pings".

Try a different wamp package such as XAMPP, WampDeveloper Pro (not free), easyPHP, etc.
