jhipster：elasticsearch节点不可用

Posted 2021-03-31

我正在使用jhipster（版本4.14.3）来生成一个Web应用程序。问题是在生产模式下，应用无法连接到端口9200上运行良好的弹性搜索服务。任何帮助都将不胜感激。

应用prod.yml：

data:
    elasticsearch:
        cluster-name: elasticsearch
        cluster-nodes: localhost:9300

elasticsearch.yml：

cluster.name: elasticsearch
path.data: C:Program Fileselasticsearch-6.2.4data
path.logs: C:Program Fileselasticsearch-6.2.4logs
network.host: 0.0.0.0
http.port: 9200
transport.tcp.port: 9300

例外细节：

org.elasticsearch.client.transport.NoNodeAvailableException: None of the configured nodes are avail
able: [{#transport#-1}{localhost}{127.0.0.1:9300}]
        at org.elasticsearch.client.transport.TransportClientNodesService.ensureNodesAreAvailable(T

        at org.elasticsearch.action.ActionRequestBuilder.execute(ActionRequestBuilder.java:86)
        at org.elasticsearch.action.ActionRequestBuilder.execute(ActionRequestBuilder.java:56)

答案

这通常是版本问题。编辑jhipster项目文件夹中的src / main / docker / elasticsearch.yml并安装相同版本的ElasticSearch服务器。
