LVS is completed separate from your cluster. Think of it as a router. It
directs traffic to your cluster whether it be master or slave so is
essentially outside of it. You *can* use real servers as directors but
it gets real messy so its much better to keep it simple.


 

So, this means that lvs set up is not necessary on cluster.....it has to be 
setup totally different(in terms of machines) and have traffic directing to 
cluster?  

 

If i want a  client to connect on the cluster director  which uses a least used 
node  and routes the incoming packets to that node that does whatever it has to 
and replies back to the client .  Where client of course is still thinking that 
it is communicating with the director.  (LETS SAY THIS IS THE TYPICAL SETUP) 
This is where I got confused that if the cluster director is same when we are 
trying to setup lvs director and if the real servers are considered to be nodes 
of the cluster....

 

because as far as I can understand...the client connects to the director and 
director calls upon a real server flagging help ...it does work and sends 
respond to the client...RIght?  

 

So, in these terms ...cluster master node = cluster director (lvs director) and 
cluster slave nodes that do the dirty work . i.e. real servers.....

 

I hope I am making sense....

 

thanks...
