Virtual Server
 

Hi guys,

I was wondering three things actually:

1. How do you determine a server's virtual ip address? Or is it something that has to be created? If yes, then does anyone know a good how-to that would help with the setup? I have googled around but didn't find anything i liked.

2. how do u set up cluster or more like one master ie. director and second slave ie. node simplest way possible?


--thanks in advance
--p

what kind of "virtual" is this? there are many many forms of resilience available through redundant system... if you want a floating IP across multiple systems, you'd start with "heartbeat" http://linux-ha.org/

Here is what I am trying to set up and I need to setup VIP. The part where I am getting confused is if the vip is set up or its just another word for localhost....VIp : it is where the ip clients connect to....
