Ask Slashdot: High-Availability/Mirroring for Linux?

marcm submitted this question: "Is there software available that will let me take two Linux boxes and have them act as one server - so that if one fails the other will still be there to fill the need. I think Sun calls this 'high availability'."

LJ article on HA linux

[jed_reynolds]

Well, I read an article in LinuxJournal on HA Linux. It basically consisted of N linux boxes connected to a common router. The router, of course, was the link to the outside. However, the router was also the most important part; it was configured such that if one of the servers went down it would forward all requests to the remaining N-1 servers. There was also some nifty tricks with DNS with this setup which I don't remember. Goto the LinuxJournal website and search thru their articles. Possibly you gould get more info from the author!
