grails - 在grails中安装elasticsearch插件时出现NoNodeAvailableException

Question

我正在开发一个grails Web应用程序(当前在本地计算机上)，该应用程序需要查询网络上服务器上的elasticsearch。

我已采取以下步骤:

在BuildConfig.groovy中添加了以下行

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

我还向Config.groovy添加了以下内容:

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

为了消除防火墙等问题，可以使用curl运行查询，它可以正常工作:

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

但是我得到以下信息:

对于类似的错误，我在这里已经阅读了许多其他答案，但我尝试过的任何方法都没有用。有任何想法吗？

Answer 1

传输在端口9300上完成(不在HTTP端口9200上完成)。还要检查该端口是否打开。

如果仍然失败，请检查是否也使用正确的cluster.name。默认情况下，它是elasticsearch，因此如果您没有在服务器/集群中对其进行更改，则不需要它。

否则，请在您的问题上添加新的见解。
