Pacemaker - Set Virtual IP Address2011/07/15 |
|
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.
