Hello, I have set up a 1 node elasticsearch cluster. I have pushed my data and set up security (xpack)

now, that I know it runs OK, I want to add 2 nodes to it to reach a 3 node cluster.

How can I proceed? is there a best practice? If I do it with 2 steps: add the 2nd node then the 3rd, I may have the split brain issue, right?

Hi Dao,

Go through this : [https://www.elastic.co/guide/en/elasticsearch/guide/current/deploy.html](https://www.elastic.co/guide/en/elasticsearch/guide/current/deploy.html)

You will get the fair idea on how to set up a cluster with different configuration changes

Thanks  
Omkar
