Kibana 3 无法连接到 elasticsearch

Question

我尝试使用 elasticsearch 和 logstash 设置 kibana 3。

当我转到 127.0.0.1/kibana 时，出现以下错误： Error Could not contact Elasticsearch at http://127.0.0.1:9200. Please ensure that Elasticsearch is reachable from your system.

当我检查控制台日志时，我得到以下信息： Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at http://127.0.0.1:9200/_nodes. (Reason: CORS header 'Access-Control-Allow-Origin' missing).

当我转到 url http://127.0.0.1:9200 时，我得到以下 JSON 文本

{
  "name" : "Meteor Man",
  "cluster_name" : "elasticsearch",
  "version" : {
    "number" : "2.1.1",
    "build_hash" : "40e2c53a6b6c2972b3d13846e450e66f4375bd71",
    "build_timestamp" : "2015-12-15T13:05:55Z",
    "build_snapshot" : false,
    "lucene_version" : "5.3.1"
  },
  "tagline" : "You Know, for Search"
}

在http://127.0.0.1:9200/_nodes 我得到以下信息：

Answer 1

你只需要在你的elasticsearch.yml配置文件中enable CORS然后重启ES，这个设置默认是禁用的。

http.cors.enabled: true

但是，我不确定 Kibana 3 是否可以与 ES 2.1.1 一起使用。您可能需要升级 Kibana 才能完成这项工作。尝试更改上述设置并查看它是否有帮助。如果没有，请将 Kibana 升级到最新版本。
