You should create a jk-enabled listener with system properties
${AJP_PORT} and ${AJP_INSTANCE_NAME} for each instance.
For example,
asadmin create-network-listener --jkenabled true --target cluster1
--protocol http-listener-1 --listenerport ${AJP_PORT} jk-listener
asadmin create-jvm-options --target cluster1
"-DjvmRoute=\${AJP_INSTANCE_NAME}"
Configure the above system properties for each instance in the cluster.
For example, for a cluster instance named "instance1", run these commands:
asadmin create-system-properties --target instance1 AJP_INSTANCE_NAME=instance1
asadmin create-system-properties --target instance1 AJP_PORT=8009
asadmin create-system-properties --target instance2 AJP_INSTANCE_NAME=instance2
asadmin create-system-properties --target instance2 AJP_PORT=8010
