我通过 logstash:7.9.1 图像使用 logstash，当我启动 docker-compose 时出现此错误，我不知道该怎么办（我尝试使我的 logstash 配置错误并将其连接到错误的弹性端口但是我的 docker 仍然连接到 9200，所以我认为它不会从我的 logstash 配置中读取它的数据）请帮助 meeeee ！！！我的错误：

[logstash.licensechecker.licensereader] Attempted to resurrect connection to dead ES instance, but got an error. {:url=>"http://elasticsearch:9200/", :error_type=>LogStash::Outputs::ElasticSearch::HttpClient::Pool::BadResponseCodeError, :error=>"Got response code '401' contacting Elasticsearch at URL 'http://elasticsearch:9200/'"}

【解决方案1】：

您在 7.9 中使用了错误的 elastic 用户密码，该密码从 changeme 更改为 password，如 ES contribution doc 所示，但我尝试过，这似乎只有在您从源代码运行 ES 时才有效代码。

无论如何你得到 401 意味着未经授权的访问，你可以阅读更多关于它here，

由于您不是从源代码运行 ES 代码，建议您按照this 线程中提到的步骤更改密码，并且当您在 docker 中运行它时，您需要通过@987654327 进入 docker 容器@ 然后运行线程中提到的命令来设置你自己的密码。
