Hello i want to create multiple nodes in single cluster in the single server what steps i need to follow i try many but not success yet i am using elasticsearch 5.4 ---

At minimum, each node needs to be configured to have the same cluster name, and the unicast discovery list must include the addresses of the other nodes. See the important settings docs here: [https://www.elastic.co/guide/en/elasticsearch/reference/current/important-settings.html](https://www.elastic.co/guide/en/elasticsearch/reference/current/important-settings.html) Once those are configured, you can just turn on the nodes and they will find each other and cluster. ---

If you want to start multiple nodes on the same machine (for tests purposes) just run: ```auto bin/elasticsearch -Epath.data=data1 -Epath.logs=log1 bin/elasticsearch -Epath.data=data2 -Epath.logs=log2 bin/elasticsearch -Epath.data=data3 -Epath.logs=log3 ``` Without changing anything in the default `elasticsearch.yml` and you should be done. ---

Hello when you run bin/elasticsearch then there are some errors if you solve all errors then it's working fine to add new node in the cluster thanks jayram ---

I am able to run 3 nodes on same server with same setup and with 3 different config files/folders sharing common cluster name node-0: default node, config file path: `${ES_HOME}/config` (no changes in elasticsearch.yml file) node-1: 1st extra node, config file path: `${ES_HOME}/config/config_node1` node-2: 2nd extra node, config file path: `${ES_HOME}/config/config_node2` Below are the changes I made in elasticsearch.yml node1 and node2 elasticsearch.yml for node-1 > node.name: node-1 > path.data: ${ES\_HOME}/data\_node1 > path.logs: ${ES\_HOME}/logs/logs\_node1 > http.port: 9201 elasticsearch.yml for node-2 > node.name: node-2 > path.data: ${ES\_HOME}/data\_node2 > path.logs: ${ES\_HOME}/logs/logs\_node2 > http.port: 9202 command for starting all 3 nodes node-0 (it will take default config folder,no need to specify) > elasticsearch.bat node-1 > elasticsearch.bat -Epath.conf=${ES\_HOME}/config/config\_node1 node-2 > elasticsearch.bat -Epath.conf=${ES\_HOME}/config/config\_node2 All 3 nodes are running fine verified in [ElasticHQ](http://www.elastichq.org/) too ---

which version on elasticsearch you are using i am on 5.4 and that's not working for me ---

I am also running 5.4.0 Try to start all instances by opening the new cmd prompt and before starting each node set `ES_JVM_OPTIONS` in `path`, and also pass for `path.conf` excluding for master node which doesn't require `ES_JVM_OPTIONS` and `path.conf` to be set/passed for starting node1 > set ES\_JVM\_OPTIONS=d:/uat/elasticsearch540/config\_node1/jvm.options > elasticsearch.bat -Epath.conf=${ES\_HOME}/config\_node1 for starting node2 > set ES\_JVM\_OPTIONS=d:/uat/elasticsearch540/config\_node2/jvm.options > elasticsearch.bat -Epath.conf=${ES\_HOME}/config\_node2 `ES_JVM_OPTIONS` is used by `elasticsearch.bat` and the path specified in `path.conf` will be used for reading `elasticsearch.yml` and `log4j properties` file. I am running 3 nodes perfectly fine. ---
