I'm pondering about the possibility of having multiple sort-of servers on one actual server.
My goal is to separate development environments. Have 1 for testing, 1 live, 1 for a mail system.
The 2 environments (testing & live) should have individual wamp setups and (of course) separate directories, and the mail just postfix and other mail related server applications. The main goal - each of them to have different outside IP addresses, so that there would be no access to the testing environment for users that use the live one. I don't want to have an actual VPS system, such as having separate installations of the OS.
Does anyone have any idea how to create such a setup? I'll be using Debian for this project.
That said, I'd strongly consider just fully virtualizing your environment if you've never done this before. If you can get around your reservation of not having separate OS installations, VMWare ESXi is free, fast, and good at what it does.
