how to run multiple elastic search (2.2) nodes as processes on the same server

i was wondering if you help me out here; am trying to run multiple elasticsearch processes on the same (CentOS) server, but i have been un-successful so far. and i have not enabled the service wrapper. and Elasticsearch has been installed using the .rpm package

the requirements are:

  1. every instance belongs to a different cluster (cluster.name)
  2. every instance uses a different port, 9201, 9202, 9203, etc.
  3. every instance should be parameterised with different ES_HEAP_SIZE

the elasticsearch.yml file is attached where all parameters are described.

and the questions are:

  1. how to set a different configuration file per instance when Des.config seems to be deprecated in 2.2
  2. how to set a custom ES_HEAP_SIZE (-Xmx=24G -Xms=24G) when

# bin/elasticsearch -Des.config=config/IP-spotlight.RRv4/elasticsearch.yml [2016-02-14 19:44:02,858][INFO ][bootstrap ] es.config is no longer supported. elasticsearch.yml must be placed in the config directory and cannot be renamed.

please help ..

You have two solutions:

  1. download elasticsearch archive from the site and run it from different paths with different configs. You can monitor each running instance with a method like supervisor. The main page for Elasticsearch downloads is here
  2. run each instance inside a docker container. This is the right way to do, because it is easier to deploy and manage. You can find a Elasticsearch docker image here
