    How to start Multiple servers (instances) in JBoss

    Mohan Mohan Newbie

      Hi,
      I want to deploy multiple applications seperately, not in a single server/deploy.
      I made copies of default servers and deployed different applications seperately when I start 2nd server it was throwing exception of already bind in use. So I modified the ports which are throwing expections for 2nd server startup so finally I end up with total 9 ports in different xml files.
      So i came to conclusion that we need to change all the ports for seperate servers. so For 3rd server again 9 different ports are required. Please any one guide me what is the solution for this?

      How to start multiple server instances (for each application one server) in JBoss with out changing the server ports.

      I chose this different server per application becuase I want some control on applications on individual basis. If I deploy all my applications at one server and when I start server all the applications will start and when I shutdown all the applications will be down, I don't want this to happen.

      If any one guide me how to start a particular ear from server/deploy that may also solve my problem.

      with regards
      Mohan

          Use the binding-manager-service.

            You know, sometimes a one-line answer is less helpfull than no answer at all.

            Mohan - I'm working on the same problem you are. First, read this:

            http://jboss.com/index.html?module=bb&op=viewtopic&t=63969

            Now, in my case, each Jboss instance is serving a domain that has it's own ip address, and therefore I can use the configuration options to set the "--host=$JBOSS_HOST" option for each instance. This allows for the RMI, JNDI, UIL2, and other ports that a JBoss server config can use to bind to that IP or Host name instead of all vying for the same IP address, which is what I think is happening to you.

            As far as I'm concerned the binding-manager-service is a programmer's solution to multiple instances, which is to say it's over-complicated and just not very helpful to 90% of the people using JBoss. For just throwing up a second server, it should have been much simpler.

            If you're going to run multiple instances of JBoss on the same IP and you don't want to have to take the time to learn the binding-manager-service, then you need to change the ports the services use for each instance. I'm working on the script referenced in the post linked above to make all this multiple instance stuff easier. I'm just getting around to taking care of ports for shared host instances, but until I do, you'll have to go into the Tomcat SAR server.xml, the jboss-service.xml, and any other assorted xml configuration files for what services you are deploying and change the ports there for each instance so no ports conflict with any others.

            I hope this helps, and as I said, I'm still working on simplifying all of this. I'll check back here if you have any other questions...

              JBoss is distributed with a configuration file for the binding service that already contains four different valid configurations that work with the default server instance.

              The only steps required are: -

              1 - Clone the default server
              2 - Edit the conf/jboss-service.xml
              a - Uncomment the binding service
              b - Specify the name of the binding configuration to use
              3 - Start the new server

                using jboss-4.0.2

                cloned the all configuration and my new configuration jboss-service.xml has this


                <mbean code="org.jboss.services.binding.ServiceBindingManager"
                name="jboss.system:service=ServiceBindingManager">
                <attribute name="ServerName">ports-01</attribute>
                <attribute name="StoreURL">${jboss.home.url}/docs/examples/binding-manager/sample-bindings.xml</attribute>
                <attribute name="StoreFactoryClassName">
                org.jboss.services.binding.XMLServicesStoreFactory
                </attribute>
                </mbean>


                And i receive this exception

                Wasnt this supposed to be working?

                  There was a service missed from the service-binding.xml for the all configuration.

                  http://jira.jboss.com/jira/browse/JBAS-1788
                  http://jira.jboss.com/jira/browse/JBAS-1819

                  You need to add: -

                  <service-config name="jboss:service=invoker,type=pooledha"
                   delegateClass="org.jboss.services.binding.AttributeMappingDelegate"
                   >
                   <delegate-config portName="ServerBindPort"/>
                   <binding port="4546"/>
                  </service-config>


                  To the ports-01 section.

                    I applied the patch found in jira, and successfully loaded two nodes on my local machine with no ports collisions however the two nodes (that share the cluster) are not talking to each other... :/ (deploying an ear to the farm directory does not deploy to the other farm directory and other issues as well that works fine while i worked with different machines...)

                    Anyone knows why?
