Hello everyone! I am using ES 5.6.2 and I created two nodes within a cluster. I simply want to have one master node and one slave node. Here are the configuration files for both of them: ``` cluster.name: nomad-cluster node.name: nomad-node-fnico-test node.master: true node.data: true path.data: /var/data/elasticsearch path.logs: /var/log/elasticsearch network.host: 0.0.0.0 network.bind_host: _global_ http.port: 9200 # transport.host: 130.183.198.7 # transport.tcp.port: 9300-9400 discovery.zen.ping.unicast.hosts: ["130.183.198.7:9200","130.183.198.71:9200"] discovery.zen.minimum_master_nodes: 1 ``` and ``` cluster.name: nomad-cluster node.name: nomad-node-fnico-test2 node.master: false node.data: true path.data: /var/data/elasticsearch path.logs: /var/log/elasticsearch # network.host: 130.183.198.7 # network.bind_ cluster.name: nomad-cluster node.name: nomad-node-fnico-test2 node.master: false node.data: true path.data: /var/data/elasticsearch path.logs: /var/log/elasticsearch # network.host: 130.183.198.7 # network.bind_host: 130.183.198.7 network.host: 0.0.0.0 network.bind_host: _global_ http.port: 9200 # transport.host: _global_ # transport.tcp.port: 9300-9400 # discovery.zen.ping.unicast.enabled: true discovery.zen.ping.unicast.hosts: ["130.183.198.7:9200","130.183.198.71:9200"] discovery.zen.minimum_master_nodes: 1 host: 130.183.198.7 network.host: 0.0.0.0 network.bind_host: _global_ http.port: 9200 # discovery.zen.ping.multicast.enabled: false -- not in ES5 ! # transport.host: _global_ # transport.tcp.port: 9300-9400 # discovery.zen.ping.unicast.enabled: true discovery.zen.ping.unicast.hosts: ["130.183.198.7:9200","130.183.198.71:9200"] discovery.zen.minimum_master_nodes: 1 ``` The nodes are on two different machines connected with an ssh connection with forwarding on the port 9200. ES on the master node works fine, but not on the slave node. This happens: ``` [2017-10-12T14:01:17,912][INFO][o.e.n.Node] [nomad-node-fnico-test2] initializing ...

The problem is that you are using port 9200 where 9300 should be used instead. Instead of ``` discovery.zen.ping.unicast.hosts: ["130.183.198.7:9200","130.183.198.71:9200"] ``` Write: ``` discovery.zen.ping.unicast.hosts: ["130.183.198.7:9300","130.183.198.71:9300"] ``` Or even easier: ``` discovery.zen.ping.unicast.hosts: ["130.183.198.7","130.183.198.71"] ``` But what do you mean by "master/slave". We don't have that notion in elasticsearch. What kind of problem do you want to solve or do you think you need to solve? ---

Yes, I changed the port to 9300 but the issue is the same. I have two virtual machines with one instance of Elasticsearch 5.6.2 on each of them. I would like a cluster with two nodes in it. One master mode on one machine and one data node on another. The idea is that my indices would furst be put on the master node and the other data node would be synced to the master node in order to have the same indices. ---

You are misunderstanding how elasticsearch works. There is no master/slave nodes. But there are primary shards and replica shards which can be allocated on any data node in the cluster. On a 2 nodes cluster (well you need at least 3 to avoid split brain), you don't need to change any setting like this. ---

I would start with explicit `network.host` not 0.0.0.0. Someone else might be able to tell you if that should work... Can you `curl` or `telnet` to port 9200 and 9300 from one VM to the other? (Also, setting one node to master does not automatically mean that the indices are first created there and then replicated to other nodes. Dedicate master nodes don't even store data.) ... Too slow 😛 ---

I will try the curl and telnet tests. I think then that I would like my primary shards on one machine and my replica shards on another. ---

For telnet, should I do telnet 130.183.198.7 9200 ? Because nothing happens when I do that. The port is probably not open. ---

This is what I get when using `telnet` and `curl` > ~ # telnet 192.168.1.110 9200 > Trying 192.168.1.110... > Connected to 192.168.1.110. > Escape character is '^]'. > > Connection closed by foreign host. > ~ # telnet 192.168.1.110 9300 > Trying 192.168.1.110... > Connected to 192.168.1.110. > Escape character is '^]'. > > Connection closed by foreign host. > ~ # curl [http://192.168.1.110:9200](http://192.168.1.110:9200) > { > "name" : "node\_name", > "cluster\_name" : "logs", > "cluster\_uuid" : "NydKtj3QSdqoiPjd189avQ", > "version" : { > "number" : "5.5.2", > "build\_hash" : "b2f0c09", > "build\_date" : "2017-08-14T12:33:14.154Z", > "build\_snapshot" : false, > "lucene\_version" : "6.6.0" > }, > "tagline" : "You Know, for Search" > } > ~ # curl [http://192.168.1.110:9300](http://192.168.1.110:9300) > This is not a HTTP port If these ports are not accessible between the VMs, Elasticsearch clustering will definitely not work.

Forgot to ask, what hypervisor are you using? If the services are running on your VMs then check network security settings. Although, as the VMs are in the same subnet, it really should work without anything. ---

I am working on a cloud computing service of my institute. I think I will just contact some collegues who manage that. I need to thoroughly check about all these network settings and make sure all the necessary ports are open. As I said, my plan was just to mirror the index I have on one machine to another machine. ---

Hello again! I found a way to make a snapshot of my index and copy the backup directory to the other server. Nonetheless, I would really like to find out how is it possible to make nodes finding each other. All my curl and telnet commands are working, the ssh connections are working too. ---

I think i will go for the Logstash solution with ES as input and output. I will open a new topic in the appropriate category. If no-one is able to answer my previous question, then I guess we can close this topic. ---

The issue is not http communication here, it's the communication between the nodes. It uses port 9300 contrarily to HTTP which uses port 9200. My curls work when I connect with SSH and port forwarding like ssh -L 9200:localhost:9200 root@ If i do this for port 9300, then my nodes still don't talk to each other. ---
