Elasticsearch基本客户端连接 [英] Elasticsearch basic client connection

问题描述

我已经在端口9300上建立了到我的远程Elasticsearch服务器的SSH隧道.

I have setup a SSH tunnel on port 9300 to my remote elasticsearch server.

在运行此基本示例时，获取示例数据从elasticsearch实例中，我得到一个" org.elasticsearch.client.transport.NoNodeAvailableException:无可用节点"

When running this basic example to get the example data from the elasticsearch instance I get a "org.elasticsearch.client.transport.NoNodeAvailableException: No node available"

Settings settings = ImmutableSettings.settingsBuilder()
            .build();

    Client client = new TransportClient(settings).addTransportAddress(
            new InetSocketTransportAddress(InetAddress.getLocalHost().getHostName(), 9300));


    GetResponse getResponse = client.prepareGet("bank", "account", "25").execute().actionGet();

推荐答案

我的设置是我从本地主机连接到在docker-container中运行elasticsearch的远程计算机，并且使用transportclient在9300端口上遇到了相同的问题与netty4.连接到隧道端口9200没问题

my setup is that i connect from my localhost to a remote machine where elasticsearch is running in a docker-container and i got the same problem on port 9300 using transportclient with netty4. connecting to the tunneled port 9200 was no problem

transport.publish_host: localhost

已修复

所以我的es.yml现在有:

so my es.yml has now:

http.host: 0.0.0.0
transport.host: 172.18.0.33
transport.publish_host: localhost

我通过以下方法来建立隧道:

and i do the tunnel via:

ssh -N -L 9300:172.18.0.33:9300 [e-mail]
