I have configured a Wildfly (teiid) cluster with a master and slave node where master and slave resides in two different hosts. so far I have used IP addresses of the hosts for 'management IP', 'public IP', 'unsecure IP' and in the slave host controller to resolve the master from the slave. This is working fine. But I need to use load balancers in front of my hosts. So I have configured a load balancer infront of each host and mapped load balancer 8080, 9990,9999 ports to my hosts port so that cluster can communicate using load balancer URLs. Then I go ahead and gave my load balancer URLs in the 'management IP', 'public IP', 'unsecure IP' and in the slave host controller to resolve the master from the slave. But slave is unable to connect to master using the master load balancer URL. It logs the following msgs on the console. WARN [org.jboss.as.host.controller] (Controller Boot Thread) WFLYHC0001: Could not connect to remote domain controller remote://internal-***********************************.us-east-1.elb.amazonaws.com:9999 -- java.net.ConnectException: WFLYPRT0023: Could not connect to remote://internal--***********************************.us-east-1.elb.amazonaws.com:9999. The connection timed out My slave configuration looks like following <domain-controller> <!-- Alternative remote domain controller configuration with a host and port --> <remote protocol="remote" host="internal-**************master elb*****************.us-east-1.elb.amazonaws.com" port="${jboss.domain.master.port:9999}" security-realm="ManagementRealm" /></domain-controller><interfaces> <interface name="management"> <inet-address value="${jboss.bind.address.management:internal-*****************slave elb*************.us-east-1.elb.amazonaws.com}" /> </interface> <interface name="public"> <inet-address value="${jboss.bind.address:internal-********************slave elb************.us-east-1.elb.amazonaws.com}" /> </interface> <interface name="unsecured"> <inet-address value="internal-*********************slave elb**********.us-east-1.elb.amazonaws.com" /> </interface></interfaces> I can successfully telnet to load balancer ports using load balancer URLs. so they are configured properly. Any ideas on how to use load balancer URLs for clustering in Wildfly.
