Hello i am using PHP API to write data into 2 nodes of the master node in single cluster how i can save the specific data into specific node via PHP REST API is there any setting to define in the REST API that Data will save in particular node ---

Not clear what you want to do but basically when you write data, you write it within an index. The index by default can be allocated anywhere on your cluster. If you want to allocate your index only on a specific set of machines, then you can tag them and use then shard allocation filtering. See [https://www.elastic.co/guide/en/elasticsearch/reference/5.4/shard-allocation-filtering.html](https://www.elastic.co/guide/en/elasticsearch/reference/5.4/shard-allocation-filtering.html) But I'm curious on the reason you think that might be a good idea in a 2 nodes context. (BTW 3 nodes should be the minimal for production to avoid split brain issues) ---

hello here is my structure Master Node = 1 data node = 2 Index = 2 i want to write the first index only in first data node and second only in second data node but the post of the node is 9301 and 9302 that not allowed to access via REST API REST API only accept 9200- 9300 hope you understand now ---

Yes. Still I don't understand why you want to do that and not let elasticsearch distribute the indices on the cluster. Anyway look at [https://www.elastic.co/guide/en/elasticsearch/reference/5.4/shard-allocation-filtering.html](https://www.elastic.co/guide/en/elasticsearch/reference/5.4/shard-allocation-filtering.html) ---

Hum... I think I understand your question. So you have 2 nodes running on the same machine? Then you want to send index requests to one of the node and other index requests to the other node. Is that right? If so, just send requests either to: - [http://127.0.0.1:9200](http://127.0.0.1:9200) or - [http://127.0.0.1:9201](http://127.0.0.1:9201) ---

you are right boss now you understand me i read your document to create the index and assign that to node via attributes of shard allocation filters that i am trying now so do you think i am on the right track ? ---

Yes. May be. I mean that you did not tell **WHY** you want to do that. What problem you think you are trying to solve here? ---

Just create one index per use case in the same node. You don't need multiple nodes and complicate things IMO. ---

May be you removed one node and you don't have replicas so no replica has been promoted. Hard to say without knowing what you are doing. But again you should really take advices that we are giving on this list seriously. Specifically I think that you have little experience with elasticsearch and you don't know yet all the internals. If I'm right with this statement I'd encourage you reading [https://www.elastic.co/guide/en/elasticsearch/guide/current/getting-started.html](https://www.elastic.co/guide/en/elasticsearch/guide/current/getting-started.html) to get a better understanding of what is happening behind the scene. Specifically this chapter: [https://www.elastic.co/guide/en/elasticsearch/guide/current/distributed-docs.html](https://www.elastic.co/guide/en/elasticsearch/guide/current/distributed-docs.html) ---

thanks to support me so far

i used code from your document and if that is useless then i think you have to update your document as well
