Re: ipvsadm

Hi Zhou,

No need to configure the real servers and LVS on same box. I have my 
real servers on different linux machines. What I meant was that I am 
not using same machine for LVS and backup instead have 2 different 
machines.

On the LVS, I have 2 NIC cards, one for private(LAN) and one for 
public(hits come here)  and have aliases for both of them.

On Backup too, I have 2 NIC cards but no aliasing is done as it has 
to take the LVS aliases when LVS is down.

The lvs.cf file is same on both and am using NAT for routing.Tested 
for 2 real servers in the cluster which are on 2 different linux 
boxes.

Hope this clears your doubt.

-P
