Logstash 在连接 AWS Elasticservice 时抛出 401

Question

我有 AWS Elastic 服务域设置，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 并设置了一个 master user 帐户来访问 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 并返回 401。

我不明白为什么会发生此呼叫。当我尝试在浏览器中点击它时，我得到 {"Message":"Your request: '/_license' is not allowed."}

这是我从 logstash 获得的示例日志：

[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
 }
}

Answer 1

问题出在 Logstash Elasticsearch 输出插件试图验证 URL <hostname>/_license.

上的许可证

参考 LS should always perform ES license check · Issue #1004 · logstash-plugins/logstash-output-elasticsearch 报告 issue/fix。

在该修复程序发布后，您可以按照以下步骤使其正常运行：

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 问题中建议的修复方法更改方法 appropriate_license。在 OSS 设置的情况下，使方法 appropriate_license() return 为真。

Answer 2

logstash 有一个 Opensearch plugin 可以解决这个问题。

cd /usr/share/logstash
bin/logstash-plugin install logstash-output-opensearch

更新 Logstash 输出插件，将 elasticsearch 替换为 opensearch

output {
    opensearch {
        hosts => "<Your ES Host>"
        ... <OTHER CONFIG>
    }
}
