Example-Registering Scalable Sun Cluster HA for Apache
For scalable services, you create two resource groups: a failover resource group that contains the network resources and a scalable resource group that contains the application resources. The following example shows how to register a scalable Apache service on a two-node cluster.
Cluster Information Node names: phys-schost-1, phys-schost-2 Shared address: schost-1 Resource groups: sa-schost-1 (for shared addresses), ap-schost-1 (for scalable Apache application resources) Resources: schost-1 (shared address), apache-1 (Apache application resource) (Add a failover resource group to contain shared addresses.) # scrgadm -a -g sa-schost-1 (Add the shared address resource to the failover resource group.) # scrgadm -a -S -g sa-schost-1 -l schost-1 (Register the Apache resource type.) # scrgadm -a -t SUNW.apache (Add a scalable resource group.) # scrgadm -a -g ap-schost-1 -y Maximum_primaries=2 \ -y Desired_primaries=2 -y RG_dependencies=sa-schost-1 (Add Apache application resources to the scalable resource group.) # scrgadm -a -j apache-1 -g ap-schost-1 \ -t SUNW.apache -y Network_resources_used=schost-1 \ -y Scalable=True -y Port_list=80/tcp \ -x Bin_dir=/opt/apache/bin -x Confdir_list=/opt/apache/conf (Bring the failover resource group online.) # scswitch -Z -g sa-schost-1 (Bring the scalable resource group online on both nodes.) # scswitch -Z -g ap-schost-1 |
