Hello, I am trying to set up a binding to a Virtual IP in order to use master and slave HAProxy load balancers. I am following each of the two following guides:
http://www.highscalable.org/haproxy-and-keepalived-for-highly-performance-load-balancing-web-technique http://www.howtoforge.com/setting-up-a-high-availability-load-balancer-with-haproxy-heartbeat-on-debian-lenny-p2 But the majority of the guides are not relevant to my problem. as far as I understand, in order for a frontend to use a different IP than the machine's IP (in an internal network), all is needed is: 1. In HAProxy.cfg set, under a listen or frontend node: bind <some-nonexistent-ip>:<someport> 2. In /etc/sysctl.conf add net.ipv4.ip_nonlocal_bind=1 and run sysctl -p At this point the <some-nonexistent-ip> should be reachable from the network? in my case, it simply doesn't happen. should I see it under ifconfig on the machine? I realize this may not be the best place to ask the question, but it's very relevant to HAProxy for redundancy purposes. I am running RHEL 5.5 Thanks
