Pacemaker - Set Virtual IP Address
2011/07/15
 
Set Virtual IP Address.
This example shows to configure on the environment like follows. 
(1)  www01.srv.world  ( eth0 [192.168.1.60],  eth1 [10.0.0.60] )
(2)  www02.srv.world  ( eth0 [192.168.1.61],  eth1 [10.0.0.61] )
This example uses eth0 for inter-connection and uses eth1 for service provider. And set [10.0.0.100] for Virtual IP Address as an example.
[1] Configure Virtual IP Address on a Host.
