I configured two-node cluster with one master node. It's Red Hat servers. Unfortunately second node cannot join to the master node. Here is configuration of master node: # Use a descriptive name for the node: # [node.name](http://node.name): "nodetwo" node.master: true node.data: false #network.host: 192.168.10.100 #transport.host: 192.168.10.1 # # Add custom attributes to the node: # #node.attr.rack: r1 discovery.zen.ping.unicast.hosts: ["192.168.10.100", "192.168.10.150"] # # ----------------------------------- Paths ------------------------------------ ---

It looks like you're setting the transport address to a different address than the you set in `discovery.zen.ping.unicast.hosts` (I say look like because you did not show both sides). Elasticsearch uses the transport address for internode communication, so you need to ensure the transport addresses and the addresses that you use in `discovery.zen.ping.unicast.hosts` are the same. ---

Right, so as I mentioned, the problem is that you have specified a different transport address than you specified in `discovery.zen.ping.unicast.hosts`. ---

Then what should I do? Is what I add transport.host: 192.168.10.150 ---

As I've explained, you set the transport address to 192.168.10.1 on your master. This is the address that you must use for internode communication. This means that your `discovery.zen.ping.unicast.hosts` should include 192.168.10.1 instead of 192.168.10.100 as there is no node listening for transport requests on 192.168.10.100. ---

I have two machines the master has the address 192.168.10.150 and the slave 192.168.10.100 I do not use the address 192.168.10.1 elasticsearch.yml > cluster.name: prod > node.name: "nodeone" > node.master: false > node.data: true > discovery.zen.ping.unicast.hosts: ["192.168.10.100", "192.168.10.150"] > transport.host: 192.168.10.150 //master Address > #[//transport.host](https://transport.host): 192.168.10.1 elasticsearch.yml //master > // cluster.name: prod > // # > //# ------------------------------------ Node ------------------------------------ > //# > // # Use a descriptive name for the node: > // # > // node.name: "nodetwo" > [//node.master](https://node.master): true > // node.data: false > //#network.host: 192.168.10.150 > // transport.host: 192.168.10.150 > // # > // # Add custom attributes to the node: > // # > // #node.attr.rack: r1 > // discovery.zen.ping.unicast.hosts: ["192.168.10.100", "192.168.10.150"] ---

From your first post: > [@karim](#): > > transport.host: 192.168.10.1 Now you've changed the configuration, but you only changed the cluster name on one of the nodes (you have `cluster.name: prod` commented versus uncommented in the two configuration files. The nodes will not join if their cluster names do not match. I think that you're making this harder than it is. Let's start two nodes, one that is master eligible, the other that is not. The master will bind to 192.168.1.232, the non-master node will bind to 192.168.1.218. Let's start with the simplest configuration that achieves this: master node (on 192.168.1.232): ```bash $ cat ~/elasticsearch/elasticsearch-5.3.0/config/elasticsearch.yml node.master: true network.host: 192.168.1.232 ``` non-master node (on 192.168.1.218): ```bash $ cat ~/elasticsearch/elasticsearch-5.3.0/config/elasticsearch.yml node.master: false network.host: 192.168.1.218 discovery.zen.ping.unicast.hosts: ["192.168.1.232"] ``` These nodes start fine, and the non-master node joins the master. From the non-master node: ```auto [2017-04-18T08:30:36,829][INFO][o.e.c.s.ClusterService] [j52qxt4] detected_master {IZnpRfC}{IZnpRfCWR-y9Fsz8HnOOxw}{iEUhEOSmTyKEfCe5EpTAuA}{192.168.1.232}{192.168.1.232:9300}, added {{IZnpRfC}{IZnpRfCWR-y9Fsz8HnOOxw}{iEUhEOSmTyKEfCe5EpTAuA}{192.168.1.232}{192.168.1.232:9300},}, reason: zen-disco-receive(from master [master {IZnpRfC}{IZnpRfCWR-y9Fsz8HnOOxw}{iEUhEOSmTyKEfCe5EpTAuA}{192.168.1.232}{192.168.1.232:9300} committed version [3]]) ``` From the master node: ```auto [2017-04-18T08:30:36,823][INFO][o.e.c.s.ClusterService] [IZnpRfC] added {{j52qxt4}{j52qxt45R4SBYnlg1g_cIQ}{RGYLtoWWR7q-TT0RH9ddsA}{192.168.1.218}{192.168.1.218:9300},}, reason: zen-disco-node-join[{j52qxt4}{j52qxt45R4SBYnlg1g_cIQ}{RGYLtoWWR7q-TT0RH9ddsA}{192.168.1.218}{192.168.1.218:9300}] ``` From `/_cat/nodes`: ```bash $ curl -XGET 192.168.1.232:9200/_cat/nodes 192.168.1.232 22 95 1 0.21 0.14 0.05 mdi * IZnpRfC 192.168.1.218 21 100 8 2.85 di - j52qxt4 ``` From here, you can add more configuration, taking one step at a time. ---

Please run `jps`, and `lsof -p 4438 -P -n` (or whatever the current pid is the next time that you execute `service elasticsearch status`) and share the output here and also show the logs from `/var/log/elasticsearch`. ---

Typically that is not enough. You often have to make a change in `/etc/security/limits.conf` or `/etc/security/limits.conf.d` (and then there are obnoxious things like some OS that ship with defaults that override your attempts (look for a file like `/etc/security/limits.d/90-nproc.conf` or the sort to see if you're going to run into this)). ---

Where did you get stuck after reading the log messages, looking at the docs for the bootstrap checks, and taking the appropriate action to address? ---
