HA-OSCAR: Five Steps to a High-Availability Linux Cluster

Creating Virtual Network Interface for HA-OSCAR Primary Server
First select Detection channel configuration shown in Figure 10, and navigate
into the corresponding screen shown in Figure 11. Initially, there should be
three network interfaces: eth0, eth1, and lo, all created during OSCAR and
HA-OSCAR installation. Add virtual network interfaces for eth0 and eth1 by
clicking on the Add a new interface button in Figure 12. Sample screens
(Figures 13 and 14) show how to add virtual network interfaces for eth0 and
eth1.

Building Detection Channel Information
After you create the virtual network interfaces, the next step is to define the previously created network interfaces for HA-OSCAR (health) detection channels. Access the detection channel configuration from the HA-OSCAR Webmin screen shown in Figure 15. When you've made your selection, enter the network interface information in the form shown in Figure 15.

When you complete the channel setup and primary server configuration, make sure to click the Save button in Figure 17 and then click the Apply configuration button in Figure 18.

Optional Steps for Managing Services Configuration
HA-OSCAR provides a useful default set of monitoring policies. However, users can add new services and change monitoring parameters. We do recommend this option for advanced users.

Return to the index page, and apply all of the configurations to HA-OSCAR.

Make sure to apply the change to the new configuration.
