Linux Web Server Load Balancing and Failover
I'm new to Linux, but I do have some experience with web servers on my Windows XP Home computer. I've ordered four 350mhz Dell computers from eBay to use as Linux web servers (in a cluster or cluster like setup). Here's what I'd like to do:
1. Configure load balancing on the web servers (without having to buy more equipment, I've heard that this may be possible with iptables but I'm not sure).
2. Configure failover, so that if one server goes down, it's detected, and browser's requests are directed to the other working servers.
3. Configure mirrored content so that the 3-4 servers grab content from another web server every 10 seconds.
Of course, since I'm new to Linux, I'd opt for the easiest and most efficient solution. Thanks in advance for your help.
