Hi all, I have setup a test environment for determining if VLS would be a good solution for balancing our multiple webservers. Currently we are using an old-fashioned DNS Round Robin setup, so anything should be an upgrade here! However, I am having a few key problems that I cannot determine the fix to, which is where I hope you can help :)
The setup: CentOS 5 server setup [weblb.domain.com] as primary VLS router (no backup in the lab yet) with one external IP address (no internal) using Direct routing with IPTables marking port 80/443 traffic with "80" 2 CentOS 5 webservers setup [web01 and web02] with one external IP each and IPTables setup for PREROUTING information. The problem: When I create my intial connection to the VIP, it passes me correctly to one of the machines. However, if I shutdown apache on that box, or poweroff the machine entirely, I am never redirected to the online box, nor do any alarms go off. I am using the default monitoring script included, and I can see it opening port 80 on both web01 and web02 (by looking at apache access logs), but it doesn't seem to want to fail over. Furthermore, if I manually go in and deactivate a Real Server, it still continues to try to send traffic to it. I have looked around on Redhat's site and the web for general debugging and troubleshooting guides, but I am at a bit of a loss. Does anyone have any suggestions on where to start looking? Is this potentially an ipvsadm or nanny issue? Thanks so much! PS - I have intentionally been a bit vague regarding some of the setup so as to not hit the list with a 3 page email. If you ask I will gladly produce more information to help in the process.
