Logstash 在连接 AWS Elasticservice 时抛出 401

问题描述

我设置了 AWS Elastic 服务域，我正在尝试通过 Logstash 将一些数据从 ec2 实例推送到 AWS elasticservice。

我已经使用 Open access policy - Allow all traffic 设置了 AWS ES 域。我还启用了 Fine Grained Control 并设置了 master user 帐户以访问 AWS ES 服务。

使用 Kibana 或常规 cURL 调用一切正常，但 logstash 失败，请求发送到 https://<my_es_hostname>/_license，响应为 401。

我无法弄清楚为什么会发生此呼叫。当我尝试在浏览器中点击这个时，我得到 {"Message":"Your request: '/_license' is not allowed."}

这是我从 logstash 得到的示例日志：

[INFO ] 2021-06-02 11:40:18.858 [[main]-pipeline-manager] elasticsearch - New Elasticsearch output {:class=>"LogStash::Outputs::ElasticSearch",:hosts=>["https://<host-name-partxxxx>.us-east-2.es.amazonaws.com:443"]}

这是我的logstash配置：

input {
  jdbc {
     jdbc_driver_class => "org.postgresql.Driver"
     jdbc_driver_library => "/usr/share/logstash/logstash-core/lib/jars/postgresql-42.2.20.jar"
     ...
     <other properties to fetch data>
 }
}
output {
  elasticsearch {
    hosts => ["https://<host-name-partxxxx>.us-east-2.es.amazonaws.com:443"]
    user => "username"
    password => "password"
    ilm_enabled => false
    index => "my_index"
    document_id => "%{id}"
    doc_as_upsert => true
 }
}

解决方法

问题在于 Logstash Elasticsearch 输出插件试图验证 URL <hostname>/_license 上的许可证。

有关报告的问题/修复，请参阅 LS should always perform ES license check · Issue #1004 · logstash-plugins/logstash-output-elasticsearch。

当该修复发布时，您可以按照以下步骤使其正常工作：

• 前往/usr/share/logstash/vendor/bundle/jruby/2.5.0/gems/logstash-output-elasticsearch-11.0.2-java/lib/logstash/outputs/elasticsearch
• 打开文件 license_checker.rb-> 根据上述 github 问题中建议的修复更改方法 appropriate_license。在 appropriate_license() 设置的情况下，使方法 OSS 返回 true。
