The setting to enable the usage of a virtual IP address.
If you select n (no), the configuration script does not configure the virtual IP address.
If you select y (yes), new configuration settings for the virtual IP address are displayed in the configuration menu. These settings are listed below in this table. If you are performing a silent installation you must also configure these parameters in the installation.properties file.
KA_ENABLED
Virtual IP address
The virtual IP address shared by all the cluster nodes.
KA_VIRTUAL_IP
Virtual IP interface
The network interface used for the virtual IP address. Unless you are using a configuration that has multiple Ethernet interfaces, you must set this value to eth0 (Ethernet-zero).
KA_INTERFACE
Virtual IP master node
Determines if the current node is the virtual IP master node. As the initial node of the cluster is usually designated the virtual IP master, set this value to y (yes), on the initial node. In addition, as the second node in a cluster is usually designated the virtual IP backup, set this value to n (no) on the second node.
KA_MASTER_YN
Virtual IP router ID
An integer with a value from 1 to 255. The value must be the same for both virtual IP master and backup. The default value is 71.
This value must be unique across Virtual Router Redundancy Protocol (VRRP) installations.
KA_ROUTER_ID
Virtual IP authentication password
The password that the backup node uses for authentication. This password must be the same as the virtual IP authentication password configured for the initial node.
