Question

我正在开发一个grails web-app（目前在我的本地机器上），需要在我的网络上的服务器上查询elasticsearch。

我已采取以下步骤：

在BuildConfig.groovy

中添加以下行

plugins {
        ...
        runtime ":elasticsearch:0.0.3.4"
        ...
    }

我还在Config.groovy中添加了以下内容：

elasticSearch {
    client.mode = 'transport'
    client.hosts = [
        [host:'xxx.xxx.xxx.xxx', port:9200]
    ]
    disableAutoIndex = 'true'
}

为了消除防火墙问题等已经使用curl运行查询，它工作正常：

curl -XGET 'http://xxx.xxx.xxx.xxx:9200/_search?pretty' -d '{...}

但我得到以下内容：

我已经在这里阅读了许多其他类似错误的答案，但我尝试过的任何工作都没有。有什么想法吗？

Answer 1

传输在端口 9300 上完成（不在HTTP端口 9200 上）。同时检查此端口是否打开。

如果仍然失败，请检查右侧cluster.name。默认情况下为elasticsearch，因此如果您未在服务器/群集中更改它，则无需使用它。

否则请在您的问题上添加新的见解。
