Just reading over your ideas, I'm not sure Apache is what you want in this case. I think it will be a lot of overhead and could be done more simply another way. I'll comment below, and then give my thoughts. > Details: > ----------- > It is my understanding that Apache can have multiple instances on a > computer.

Possible? Yes. You can provide both MySQL and Apache with config files when you start up that will point them to the correct directories. But knowing what those directories are might prove to be a challenge. You need to write a front end program to figure out which drive is the CD-ROM drive, and then point Apache and MySQL to the config files on that drive. You may even have to generate some config files on the fly since you will need full path names in a few places. > 2) If so, please provide a hint of where to look for the answer or what to > do. (I am new to Apache.) Start reading Apache and MySQL documenation. Especially the parts about running as non-root (or non-admin users), and the parts about multiple instances on a machine. > 3a) Can I have multiple instances of PHP 4.3 and higher on a > laptop/desktop?

You just give it different parameters. MySQL can listen on any port, and since you are going to be using this locally, I would recommend you tell it to --skip-networking and connect via a local socket (this might not work on windows, though). Comments. I understand you want to use a web server because it handles a lot of the client/server processing for you. But an Apache server plus a MySQL server is going to be way to much overhead for a project like this. I would wager that Apache + MySQL is going to be larger than your dataset. If you *insist* on going with a web server, I would check out <http://www.lighttpd.net/> (heresy to suggest that here, I know). Much smaller, and would do what you want. Suggestion (and in my opinion a much better idea). Since all you want is a light program to access data (and print out some things), you really need a front end to a bunch of data. For embedded databases, there is a mysqllib that lets you read and write mysql data files without running a server. There is also sqlite <http://www.sqlite.org/> which would probably be more than sufficient for your needs. Then, once you have the data in place, you can write a lighter front end program to read the write the data. Using Macromedia Director or Flash comes to mind. Personally, I would write it in Qt <http://www.trolltech.com/products/qt/>, then you can compile it to run on Windows, Mac, and Unix. And Qt has built in drivers for Sqlite. That way, you don't need to run a server and don't need to worry about existing installation. Much simpler in my mind. If you have any more questions, reply off list, as I'm sure this will get quickly off-topic. j----- k----- -- Joshua Kugler CDE System Administrator http://distance.uaf.edu/ --------------------------------------------------------------------- The official User-To-User support forum of the Apache HTTP Server Project.
