How to set Listen Port to 81?

[tomhirt]

I can't use the default port 80, as this is my second web server. And since I can't get a dedicated IP for this server, I think I should be able to set it up to use port 81....correct?

Where is this done? And please, give noob directions. Thanks!!

set Listen to 81 in httpd.conf and (if necessary) Servername from localhost:80 to localhost:81
