Hi,

I would to run two or more instances of ES on my server but on different ports.  
e.g. [http://localhost:9200](http://localhost:9200), [http://localhost:9201](http://localhost:9201) ...

I created two different "elasticsearch.1.yml & elasticsearch.2.yml" with respected port numbers (http.port:9200 & http.port:9101), logs and data paths. The mentioned config files located under "elasticsearch-5.1.2/config/" folder. I tried to run "bin/elasticsearch -d" but it shows me only the instance with port 9200.

Can you please tell me where i am wrong and what have to do?

kind regards

First of all don't do that. Unless you have more than 64Gb of RAM on your machine.

Then, only `config/elasticsearch.yml` is read.  
You can create multiple config dirs if you wish and then start elasticsearch with `-Epath.conf=config1`.

Read [https://www.elastic.co/guide/en/elasticsearch/reference/5.3/settings.html#\_config\_file\_location](https://www.elastic.co/guide/en/elasticsearch/reference/5.3/settings.html#_config_file_location)

Thanks a lot, it helps me 😉

I would like to add some other points to your suggested solution which may help others:

1. For older version of Elasticsearch the command looks a bit different  
e.g. ES version 1.6. `bin/elasticsearch -d -Des.path.conf=config1`

2. For each instance you need to create 'config, data, and logs' folders. e.g. create config1, config2, ...

3. You may change '[cluster.name](http://cluster.name), [node.name](http://node.name), path.data, path.logs and http.port' in config files "elasticsearch.yml" in config1 and config2 folders accordingly
