java - Multiple akka system in a single pc -

how can run multiple akka nodes in single pc? currently, i've following in application.conf file. each system, added different port numbers, but, can't start more 1 instance. error says, address in use failed bind.

application.conf file

remotelookup {   include "common"    akka {     remote.server.port = 2500     cluster.nodename = "n1"   } } 

update : multiple akka nodes means, have different different stand alone server application, communicate remote master node using akka.

the approach using is:

create different settings in application.conf each of systems:

systemone {   akka {     remote {       enabled-transports = ["akka.remote.netty.tcp"]       netty.tcp {         hostname = ${public-hostname}         port = 2552       }     }   } }  systemtwo {   akka {     remote {       enabled-transports = ["akka.remote.netty.tcp"]       netty.tcp {         hostname = ${public-hostname}         port = 2553       }     }   } } 

application.conf default config file, in settings module add configs systems:

object configs {   private val root = configfactory.load()   val 1          = root.getconfig("systemone")   val 2          = root.getconfig("systemtwo") } 

and create systems configs:

val 1 = actorsystem("systemname", one) val 2 = actorsystem("anothersystemname", two) 

don't forget system names must differ
