neo4j_embedded_ha.groovy

/*

small groovy script to demo how to spawn a neo4j ha instance from own code *and* run a server on top of it

requirement for this script:
* a 3 member cluster is assumed, so either use this script 3 times with adopted config or run 2 Neo4j servers + this script
* have two files neo4j-server.properties and neo4.properties in the same directory with this script, having the following contents:

neo4j-server.properties:
========================
org.neo4j.server.database.location=/tmp/dummy
org.neo4j.server.webserver.port=7476
org.neo4j.server.webserver.https.enabled=false
org.neo4j.server.webadmin.rrdb.location=data/rrd
org.neo4j.server.webadmin.data.uri=/db/data/
org.neo4j.server.webadmin.management.uri=/db/manage/
org.neo4j.server.db.tuning.properties=neo4j.properties
org.neo4j.server.manage.console_engines=gremlin, shell
org.neo4j.server.database.mode=HA
org.neo4j.server.http.log.enabled=false
org.neo4j.server.http.log.config=conf/neo4j-http-logging.xml

neo4j.properties:
=================
keep_logical_logs=true
ha.server_id=3
ha.initial_hosts=:5000,:5001,:5002
ha.server = :6003
ha.cluster_server=:5002
