Your log.txt doesn't look right. Only a host controller is started - no server running your idbt-ha profile is started at all.

There should be entries in the log looking like:

[Server:configuration-server-demosetup] 15:58:05,712 INFO  [org.jboss.modules] (main) JBoss Modules version 1.4.3.Final
[Server:configuration-server-demosetup] 15:58:06,017 INFO  [org.jboss.msc] (main) JBoss MSC version 1.2.6.Final
[Server:configuration-server-demosetup] 15:58:06,118 INFO  [org.jboss.as] (MSC service thread 1-6) WFLYSRV0049: WildFly Full 9.0.1.Final (WildFly Core 1.0.1.Final) starting
...


There must be a problem with your host.xml file. You should have a server definition there referring to one of your server groups, for example:

<servers>
        <server name="configuration-server-demosetup" group="group-authentication"/>
        ...
</servers>

Also, in domain-idbt.xml your Infinispan cache is configured to be local. For distributed setup you should be using distributed Infinispan cache:

              <cache-container name="keycloak" jndi-name="infinispan/Keycloak">
                    <transport lock-timeout="60000"/>
                    <invalidation-cache name="realms" mode="SYNC"/>
                    <invalidation-cache name="users" mode="SYNC"/>
                    <distributed-cache name="sessions" mode="SYNC" owners="1"/>
                    <distributed-cache name="loginFailures" mode="SYNC" owners="1"/>
              </cache-container>

Hi Marko,

thanks for your hints, I went through but still w/o positive result.
I will write my comments inside your hints.
I attached 2 files: domain-idbt.xml - with added sections for keycloak
                          log.txt - log after start wildfly in command line

Br,
Andrej.

From your descriptions of the problem it sounds like your server-one which binds to port 8080 doesn't have keycloak-server configured at all - it's using a server group, that uses a different profile than the one you configured.
    Our group/server/profile setup looks like:
   
  GROUP SERVER PROFILE
  configuration configuration-server-demosetup idbt-ha
  authentication authentication-server-demosetup idbt-ha
     

There are four profiles in the default domain.xml - default, ha, full, and full-ha
    In our domain-idbt.xml are only 2 profiles:idbt-ha and idbt-security and I modified inifinispan for idbt-ha (but ha is only in name not used inside configuration) 

If you want your multiple Keycloak instances to run in high availability mode, using a shared Infinispan cache, and a shared database, then that's the most complex of all configurations - you have to setup a standalone database, use "full-ha" profile to configure the datasource with proper database connection url, and configure the distributed Infinispan cache. Also add <subsystem xmlns="urn:jboss:domain:keycloak-server:1.1"> declaration.

    I created Keycloak_DS, which was before missing.
    I add : extension; inifinispan and subsystem section for Keycloak inside my domain-idbt.xml (I attached finally modified domain-idbt.xml) Pls you can check it inside. 
 

In server-groups section define a new group or reuse existing one, and set its profile to "full-ha", and use "full-ha-sockets" binding group.
In host.xml make sure that server definitions have the proper group set.

Then you also have to copy some configurations.

Assuming you have two servers defined in host.xml - called server-one, and server-two, create a directory:

$WILDFLY_HOME/domain/servers/server-one/configuration
$WILDFLY_HOME/domain/servers/server-two/configuration

Then copy the following configurations from standalone/configuration:

cp $WILDFLY_HOME/standalone/configuration/keycloak-server.json $WILDFLY_HOME/domain/servers/server-one/configuration/
cp -r $WILDFLY_HOME/standalone/configuration/themes $WILDFLY_HOME/domain/servers/server-one/configuration/
cp -r $WILDFLY_HOME/standalone/configuration/providers $WILDFLY_HOME/domain/servers/server-one/configuration/

cp $WILDFLY_HOME/standalone/configuration/keycloak-server.json $WILDFLY_HOME/domain/servers/server-two/configuration/
cp -r $WILDFLY_HOME/standalone/configuration/themes $WILDFLY_HOME/domain/servers/server-two/configuration/
cp -r $WILDFLY_HOME/standalone/configuration/providers $WILDFLY_HOME/domain/servers/server-two/configuration/

  Done all creation and copying steps.
