Hi, Let me specifying the problem, in details.
I want to serving a website with two machines (A,B), in loadbalancing-failover enviroment. I have two IP-s, assuming 10.0.2.40 and 10.0.2.39. The dynamic part of the site will be served by apache+php, listening on 10.0.2.40:80, and the static part of the site (css,images) will be served by a lighttpd, listening on 10.0.2.39:80 If apache runs on the box A, and lighttpd runs on the box B, both of the machines are SPOF, so I have to think up something. I plan to use IPs as VIP addresses, and I want to use 4 more IPs as realservers. Like this, one box can serve the whole page, and the other box is not idle. haresources: deb1 \ ldirectord::ldirectord.cf \ LVSSyncDaemonSwap::master \ IPaddr::10.0.2.40/24/eth0/10.0.2.255 \ IPaddr::10.0.2.39/24/eth0/10.0.2.255 \ My ldirectord.cf look like: virtual = 10.0.2.40:80 real = 10.0.2.10:80 gate 10 real = 10.0.2.11:80 gate 10 service = http scheduler = rr protocol = tcp request = "test.html" receive = "OK" checktype = negotiate virtual = 10.0.2.39:80 real = 10.0.2.20:80 gate 10 real = 10.0.2.21:80 gate 10 service = http scheduler = rr protocol = tcp request = "test.html" receive = "OK" checktype = negotiate The IPs 10.0.2.10 and 10.0.2.20 are on the box A, and the IPs 10.0.2.11 and 10.0.2.21 are on the box B. I need setting up dummy0 and dummy0:0 interfaces on both of the machines with 10.0.2.39 and 10.0.2.40, thus apache and lighttpd can bind on this IPs. Now comes the problem: If the heartbeat starts, it drops the dummy0:0 interface with IP 10.0.2.39, but the 10.0.2.40 on the dummy0 remains untouched. This reason the lighttpd can't serve request on this IP. If I call ifdown dummy0:0 and ifup dummy0:0, the system works perfectly. How can I make it reboot-safe, and failover safe?
