[Linux-HA] 3 Nodes with 2 Frontend and 1 Backup

[Joe P.H. Chiang]

Hi Thank you for your reply
this video may show the better idea with configuration and video of the 3
nodes and the problem i have..
http://www.youtube.com/watch?v=jCCqRGF90RE

When lb1 was suspended via vmware
immediately the lb2 and lb3 start to listen to
lb1's virtual ip address

what i want is that only lb3 listens to lb1's virtual ip

and then when lb3 is goes down(suspended via vmware) the lb2 to listen lb1's
virtual ip which is 192.168.19.101

and how do i do that?

Problem:
When load balancer 1 is down then the load balancer 2 and load balancer 3
automatically listen to virtual IP of load balancer 1

Setup: 3 Nodes, 2 Active 1 Backup
Load Balancer 1= Front end
Load Balancer 2= Front end
Load Balanccr 3= Backup

lb1 Virtual IP = 192.168.19.101
lb2 Virtual IP = 192.168.19.102

lb1 Physical IP = 192.168.19.128
lb2 Physical IP = 192.168.19.135
lb3 Physical IP = 192.168.19.132

I hope you guys can understand my poor English this time
Thanks

Joe
