解決方法：

修改es配置檔案（elasticsearch-2.3.3\config\elasticsearch.yml），

修改network.host

network.host：伺服器IP地址

補充說明：

如果你的java程式碼連線方式為下面的程式碼，要在配置檔案中存在此結點。

            Settings settings = Settings.settingsBuilder().put("cluster.name","my-application").put("client.transport.sniff", true).build();
            client = TransportClient.builder().settings(settings).build().addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName(ipAddress1), iPort1));

注意一下，cluster.name在es配置檔案（elasticsearch\config\elasticsearch.yml）存在。

然後,特別注意  

java埠9300，http埠9200  

 不要把 9200 埠放程式碼中去連線...
