I'm a student researching on elastic search and i am trying to configure my elastic nodes to work with each other which are hosted in digital ocean droplets. Can anyone help me? thanks in advance. ---

I actually could not find any resource regarding my problem. i Could only find resources on configuring ES on aws. im very much new to ES and I tried it in my local network but in digital ocean there are public IPs. and sorry if the question feels dumb. 😃 thank you very much Mark for the quick reply ---

Basically it's [this](https://www.elastic.co/guide/en/elasticsearch/guide/current/_add_failover.html#_add_failover). Your `cluster.name` needs to be the same on each node, you need to set `discovery.zen.ping.unicast.hosts` and `discovery.zen.minimum_master_nodes` as well. Have a read of [https://www.elastic.co/guide/en/elasticsearch/guide/current/\_important\_configuration\_changes.html](https://www.elastic.co/guide/en/elasticsearch/guide/current/_important_configuration_changes.html) ---

Thanks for the information. i went through the documentation and changed the config files of the 2 nodes. the settings are both have the same cluster name and diffarant node names both have network.host and transport.host set to 0.0.0.0 both have minimum\_master\_nodes set to 1 and multicast disabled unicast host are set to each other eg node 1 unicast.hosts [node 2 ip] but when i check for the cluster health it only shows that there is only one node. ---

You make several mistakes. - in order to make ES failsafe in a distributed manner, you need at least 3 nodes, and an odd number of master nodes. 2 master nodes are prone to a split brain situation. - therefore `minimum_master_nodes` must be set to greater as 1 - the setting `0.0.0.0` is mostly not working in cloud environments. You have to enable a private sub net and use the IP you get assigned from your cloud provider. ---

Thnank you very much for the help jPrante. I thought of carrying out my research in my local network so i could avoid the complications. Thank you again for the help. 😃 ---
