I'm a new when it comes to LVS. I recently set up a load balanced
cluster with 2 real web servers and 1 load balancer. I used ldirectord
to configure ipvsadm on the load balancer. To get the load balancer to
listen on the virtual port I went into the console and typed
"eth0:0 192.168.0.114 netmask 255.255.255.0 broadcast 192.168.0.114"

I would be surprised if ethernet aliases work anymore.

To then get the real servers to listen on this virtual IP i had to
type the same thing into their console also. Is this correct? My
problem comes in when a user sends a web request and it gets mapped to
one of the real servers and not to the load balancer.

that's how it's supposed to work.


If the request
does go to the load balancer the cluster works.

the director is just a router with funny rules. The request is routed through the director to the realservers




Did I do something
wrong? Half the time it goes straight to the load balancer and half
the time it goes straight to one of the real servers.

have you handled the arp problem?
