Hi
I trying to replace your Apache Httpd with mod_cluster load balancer with Undertow
frontend modcluster as part of Wildfly 9.0.1.
It works fine when I define a 'real' IP address defined in /etc/hosts:
127.0.0.1 localhost
10.22.62.40 mdzhrnesir01.standard.six-group.net mdzhrnesir01
But this IP address 10.22.62.117 is not taken by untertow:
ip addr
.
8: bond0: <BROADCAST,MULTICAST,MASTER,UP,LOWER_UP> mtu 1500 qdisc noqueue state
UP
link/ether 00:17:a4:77:f0:b6 brd ff:ff:ff:ff:ff:ff
inet 10.22.62.40/24 brd 10.22.62.255 scope global bond0
inet 10.22.62.117/24 scope global secondary bond0
I also faced to problem, that running the example presented by Stuart Douglas doesn't
work inside a docker container. Even I execute step by step.
Without digging into the source code, what are the criteria under which Undertow frontend
modcluster accepts IP address(es)?
Do you also have a proposal for configuring Undertow modcluster to listen to two
interfaces? Say an internal IP address and an virtual external IP address?
I think with Apache, we defined 0.0.0.0 and then Apache with mod_cluster was listening on
all interfaces, if I remember correctly.
Thanks a lot in advance

Are you using Wildfly or standalone Undertow? The procedure for configuring a listener is
different for each. For Wildfly just add a socket binding to the interface you want to
listen on then add a http-listener in the Undertow subsystem that references that
binding.
For standalone Undertow simply call addListener() multiple times for each interface you
want to listen on.

New subject: Frontent Load Balancer with Mod-Cluster using a virtual IP address
Thanks a lot Stuart, you pointed me to the right direction. We are using Wildfly. I added
a new interface and added a second socketBinding as you have described. That works nicely.
Really cool, the interface can be configured to listen on a nic name too. This is exactly
what I am looking for.
What I didn't manage is only to open the management console. What is the path for
accessing the management console? I saw in some tests "/mod_cluster_manager" but
I was not able to access the console with this path.
I think, it would make sense to update the official wildfly undertow load balancer
documentation:
https://docs.jboss.org/author/display/WFLY9/Using+Wildfly+as+a+Load+Balancer
Thanks again
Ralf

Dear Ralf,
there is no such page as /mod_cluster_manager with
Undertow mod_cluster proxy.
One uses JBoss CLI to retrieve runtime information
such as registered workers, their load and deployed contexts.
For instance:
/subsystem=undertow/configuration=filter/mod-cluster=modcluster:read-resource(include-runtime=true,
recursive=true, recursive-depth=10)
{
"outcome" => "success",
"result" => {
"advertise-frequency" => 10000,
"advertise-path" => "/",
"advertise-protocol" => "httpd",
"advertise-socket-binding" => "mod-cluster-adv",
"broken-node-timeout" => 10,
"cached-connections-per-thread" => 5,
"connection-idle-timeout" => 60,
"connections-per-thread" => 10,
"health-check-interval" => 10000,
"management-access-predicate" => undefined,
"management-socket-binding" => "http",
"max-request-time" => -1,
"request-queue-size" => 10,
"security-key" => undefined,
"security-realm" => undefined,
"worker" => "default",
"balancer" => {
"qa_balancer" => {"node" => {"worker-2"
=> {
"load" => 89,
"status" => "NODE_UP",
"context" => {"/clusterbench" => {
"requests" => 0,
"status" => "enabled"
}}
}}},
"mycluster" => {"node" => {"worker-1"
=> {
"load" => 87,
"status" => "NODE_UP",
"context" => {"/clusterbench" => {
"requests" => 0,
"status" => "enabled"
}}
}}}
}
}
}
Cheers
