akkacluster

demo java app implementing Akka cluster sharding

installation

  • compile and generate the tarballs

mvn clean install

  • extract the tarballs in suitable directories

mkdir -p ~/backend; cd ~/backend; tar xzvf $PATH_TO_REPO/akkacluster/backend/target/backend/target/akkacluster-$APP_VERSION.tar.gz mkdir -p ~/frontend; cd ~/frontend; tar xzvf $PATH_TO_REPO/akkacluster/frontend/target/frontend/target/akkacluster-$APP_VERSION.tar.gz

Startup

  • start 2 backend nodes and 1 frontend node as separate JVM processes

  • First backend to run on default port 2551 (this is also the cluster seed, so it must run first) cd ~/backend; java -cp "config:lib/*" demo.akka.backend.BackendApp

  • Second backend to run on port 2552 java -cp "config:lib/*" -Dakka.remote.netty.tcp.port=2552 demo.akka.backend.BackendApp

  • Frontend to run on default port 2550 cd ~/frontend; java -cp "config:lib/*" demo.akka.frontend.FrontendApp
