Hi,
If I'm not mistaken, this has been done and is in constant use on big sites like SourceForge and the like. I'm not sure of the details of the operation, but I seem to remember reading an overview about it on the site somewhere. They do, however, have lots of money to burn on load balancers. While there are free solutions to do this sort of thing, I don't know about them.
I suggest reading up on the MySQL docs to find out how to set up the MySQL side of things. As for Apache, it might be harder without a dedicated piece of kit to decide which server to send packets to. If the only problem you're having is Apache / MySQL crashing, you chould have a look at monit, which does a great job of restarting services that fall over and can notify you of what's happening by email.
HTH, Chris

Hi,
I am running apache/php and Mysql on my gentoo server. I just backup tar copies everyday. When the system is down, it is very difficult to recover it. So I'd like to make automatic backup(or load ballancing) system for my site.
How can I implement this on gentoo machine. One is main web&db server. and there is second server sync data in real time. When main server is down, second server should do the job of main server. And data needs to be backuped in realtime(or everyday... real time syncing is much better~)
Is anybody implemeted this? Give me some ideas...
Thanks.
