Hi, I am new in ES, I want to use multiple clusters to store data.  
My OS is windows 10.  
How could I set up the multiple cluster?Tune the config ? or doing something?

this is the Elasticsearch.yml:

thank you in advance!

Hi,

Just mention your requirement that how many nodes you have for configuration of ES cluster.  
for ES cluster best approach to use more than 2 nodes and then do configuration settings according to that.

I need two nodes to store data.  
But I don't know how to set up it \>\<

with two nodes set up, you should follow the steps:  
1: make sure cluster name in elasticsearch.yml file is same.  
2: both VM ip (both nodes IP) should be mentioned in "discovery.zen.unicast.hosts" parameter as:  
discovery.zen.unicast.hosts: ["host1 IP", "host2 IP"]  
3: both nodes should be reachable i.e. both are able to communicate . for this make sure both host IP in /etc/host file on each node.  
4: network.host parameter should be set as "localhost"  
5: port 9200 and 9300 should be open on both nodes.

thanks for your reply 🙂 .this is my config:  
Is it set up correct ?

# ======================== Elasticsearch Configuration =========================

# ---------------------------------- Cluster -----------------------------------

# 

# Use a descriptive name for your cluster:

# 

#[cluster.name](http://cluster.name): my-application

# 

# ------------------------------------ Node ------------------------------------

# 

# Use a descriptive name for the node:

# 

#[node.name](http://node.name): node-1

# 

# Add custom attributes to the node:

# 

#node.attr.rack: r1

# 

# ----------------------------------- Paths ------------------------------------

# 

# Path to directory where to store the data (separate multiple locations by comma):

# 

path.data: /path/to/data

# 

# Path to log files:

# 

#path.logs: /path/to/logs

# 

# ----------------------------------- Memory -----------------------------------

# 

# Lock the memory on startup:

#bootstrap.memory\_lock: true

# 

# Make sure that the heap size is set to about half the memory available

# on the system and that the owner of the process is allowed to use this

# limit.

# 

# Elasticsearch performs poorly when the system is swapping the memory.

# 

# ---------------------------------- Network -----------------------------------

# 

# For more information, consult the network module documentation.

# For more information, consult the zen discovery module documentation.

all configuration settings is correct except only one thing.  
make sure network.host value should be node specific ip for both nodes.  
both value should be different as per node ip.

try out with correct syntax for cluster name and node name parameter as:  
cluster.name : clustername  
(parametername space then colon again space then value)

node.name : node name

@poojagupta thank you!  
I have two nodes now.  
"nodes" : {  
"CjNQHxfNTcaJ5jsDfNsx9w" : {  
"name" : "howard",  
"ephemeral\_id" : "Y1rP56oARwuZvVJM\_ZEQvQ",

"transport\_address" : "192.168.0.159:9300",  
"attributes" : { }  
}  
},

but on howard ES command line it shows me the warnning.

As seeing logs it seems there is duplicacy in indices. you have created some indexes with that node that is overlapping now while starting cluster.  
for it you can try out with changing node name and again restart the ES cluster.

I change one of the node name howard-\>Howard  
the situation is the same . Or should I delete all the same indices?  
thank you ！

or because I didn't set the data path separately?

yes there is some issue with your created indices . for resolving it clear all data (old indices) and also change the cluster name for all nodes and again try to join it i.e. start the elasticsearch on both nodes after changing cluster name and deleting indices. Doing so, it will create new cluster with new data.

Now I have two nodes in the same cluster , one node.name is howard another is test1  
but on node.name:howard host I query the node state:  
[http://192.168.0.116:9200/\_cluster/state?pretty](http://192.168.0.116:9200/_cluster/state?pretty)

on node.name:test1  
[http://192.168.0.159:9200/\_cluster/state?pretty](http://192.168.0.159:9200/_cluster/state?pretty)  
 ![image](https://us1.discourse-cdn.com/elastic/original/3X/1/f/1f5d688dbf9e9b48e66b74dad98c16ffc89da9eb.png)  
there's only one node  
I don't know how to explain it, I think it should display both nodes on each host.

thank you very much!
