title: Setting multi node on Elasticsearch 2.0
body: <p>I started to use Elasticsearch 2.0. When I want to use multiple node on one cluster, it seems it's not not working. </p>
  
  <p>I tried two different methods to create multi node. </p>
  
  <p>First, I used my localhost and created two instances of Elasticsearch. </p>
  
  <p>Second, I used two different computers (one instance on my local computer and one instance in server and I used <code>discovery.zen.ping.unicast.hosts</code> to bind them) for this multi node. </p>
  
  <p>It's different from Elasticsearch 1.x version. And I read that multicast has already removed. So how to setting the config file for multi node on a cluster in Elasticsearch 2.0??</p>
  
  <p>Here is my config setting for different server</p>
  
  <pre><code>cluster.name: "cluster_node_1"
  node.name: "test1_node1_ES2"
  http.cors.enabled: true
  index.number_of_shards: 5
  index.number_of_replicas: 1
  transport.tcp.port: 9300
  http.port: 9200
  http.cors.enable: true
  network.bind_host: 10.21.126.151
  network.publish_host: 10.21.126.151
  network.host: 10.21.126.151
  discovery.zen.ping.timeout: 3s
  discovery.zen.ping.unicast.hosts: ["10.21.126.151", "10.21.126.145"]
  </code></pre>
  
  <p>Thanks</p>
