10.2. Configuring Multicast for Load Balancing
mod_cluster can use multicast signals to inform nodes which proxy servers are available. This allows nodes to register themselves automatically to the domain.
As a subset of the registration process, nodes can be directed to a specific domain or load balancer.
Note
Multicast is configured by default.
- Click the Inventory tab in the top menu.
- Select Servers - Top Level Imports in the Resources menu table on the left. Then select the JBoss EAP 6 server which hosts the
mod_clusterservice (the master node). - Navigate to the
mod_clusterservice resource.
- Click the Configuration tab on the resource entry.
- Go to the Advertise Options section.
- Change the multicast settings.To use a specific load balancer for the
mod_clusternodes, set the Balancer field to the load balancer name and, optionally, the Domain field to the load balancer group, which is one of the groups configured on the balancer itself.Important
The Balancer and Domain values must match the configuration for the corresponding Apache server. - Click the button at the top of the page.
