   == Start the Neo4j Servers in HA mode ==
   
  -In your 'conf/neo4j.properties' file, enable HA by setting the necessary parameters for all 3 installations, adjusting the +ha.server_id+ for all instances.
  +In your 'conf/neo4j.properties' file, enable HA by setting the necessary parameters for all 3 installations.
   Neo4j HA uses two ports, one for transmitting data and one for cluster coordination.
   The cluster coordination port is by default set to a range, and Neo4j will try to bind in this range on startup, so there is no need to specify port number for that.
   The config files should include the following:
   
  -[source,properties]
  -----
  -#$NEO4J_HOME1/conf/neo4j.properties
  -#unique server id for this graph database
  -#can not be negative id and must be unique
  +[TIP]
  +The amount of necessary configuration increases for a cluster where many instances lives on the same physical machine, due to port clashes. 
  +This will be reduced further as HA develops.
