lagom-java-ec2 with jdbc or cassandra, custom deploy (no conductR)

JDBC

I Used PGAdmin to do the following

* Install postgres
* Create a db called "playdb"
* Create a login/role called "playuser" with passwword "playuser"
* Grant this role permissions to playdb


In hello-impl/application.conf the following is used for db connection:

db.default {
  driver = "org.postgresql.Driver"

  #jdbc:postgresql://localhost/playdb is fine... mine runs on 5433, so I put it there, usually its 5432
  url = "jdbc:postgresql://localhost:5433/playdb"

  username = playuser
  password = playuser
}

Cluster

The recommendation is to have an akka cluster per service (NOT leveraging cluster for service discovery, ie. multiple
services in one cluster).


The following in hello-impl/application.conf set this up:

akka{
  remote {
    netty.tcp {
      hostname = "127.0.0.1"
    }
  }
}

and in hello-impl/start.sh

CONFIG="-Dhttps.port=9443 -Dplay.crypto.secret=$PLAY_SECRET  -Dakka.cluster.seed-nodes.0=akka.tcp://application@127.0.0.1:2552 -Dakka.remote.netty.tcp.port=2552"

java -cp "target/hello-v1/hello/lib/*" $JAVA_OPTS $CONFIG play.core.server.ProdServerStart

Maven package and run

start first node:

hello-impl/start.sh (zip, unzip, and run).

start second node:

hello-impl/start2.sh
