I am working on elasticsearch 6.5 and i don't know much about it , so my task is to add cluster node , i guess initially number of node is 1 right? if i am right then please tell me how can i make it up to 6, i already read the documentation but i can't get it, one more suggestion i got to install elasticsearch multiple time and give different node name or something like that but what i feel is there must be some simple way to do it actually this is the exact requirement that i want:- **Cluster Nodes** : 6 **Master Eligible Nodes** : 2 (both the micro instances). These are Master only nodes. **Data Only Nodes** : 4 (2 regular nad 2 preemptible instances) **Number of shards** : 8 **Number of replica sets** : 2 ---

- Start a new machine - Install elasticsearch - Configure elasticsearch as per documentation - Start elasticsearch And repeat that again. ---

Well thank you , but i want to do it in same machine , is it possible or i am going wrong ? ---

It is. Specifically if you have more than 64gb of RAM available, then I'd start 2 nodes with 30gb heap each and one tie breaker master only node with 4 or 8gb. Is it the case? If not, I don't see a lot of value of doing so. Why do you want to do this? ---

ohh well i don't have 64gb of RAM , let me explain you whole scenario i am using google cloud platform and my senior ask me to configure elasticsearch with the above requirement , requirement as i mentioned above with cluster node 6 and all. so i thought first i should practice to add the node in my own machine then i will shift to google cloud but as you tell we need 64gb of RAM to do this, but i don't have 64GB of RAM. also tried steps of this link but it not worked or may be i did something wrong, can you please go through this link and tell is this the right way to complete my task.

The easiest thing to do is to create a cluster on [cloud.elastic.co](http://cloud.elastic.co) on GCP platform in the same region you have your other services running and just set the memory size that you need. Why 6 nodes are needed in your case? Do you know? ---

Ok so you are asking me to set the size of GCP instance i mean system memory size ? Sorry i don't know about that. But i will ask. or is there any way to allocate memory to nodes like each node will take 1GB or something , i know i am asking very silly question. ---

I did not mean anything like that. Again: > Why 6 nodes are needed in your case? Do you know? What is the output of: ```auto GET / GET /_cat/nodes?v GET /_cat/health?v GET /_cat/indices?v ``` If some outputs are too big, please share them on [gist.github.com](http://gist.github.com) and link them here. ---

Please don't post images of text as they are hardly readable and not searchable. Instead paste the text and format it with `` icon. Check the preview window. You don't have any data? While you are asking questions, could you also ask why you are starting with a 6.5 version instead of 7.2? ---

output of the command that you asked for : [https://gist.github.com/ayush-ashu/4db540b956a33a5cb170fd422e703b55](https://gist.github.com/ayush-ashu/4db540b956a33a5cb170fd422e703b55) and i asked about nodes , he simply replied that we are handling very large data that's why need 6 node(Although he was also not sure). ---
