我正在尝试在我的 ubuntu 服务器上访问弹性搜索，但在浏览器中出现 502 错误。/var/log/elasticsearch/elasticsearch.log里面的东西看起来没什么用。xpack.security.enabled: true设置后开始出现错误/etc/elasticsearch/elasticsearch.yml。删除该行后，它仍然不接受连接。

来自 Elasticsearc 官方指南

启用 Elasticsearch 安全功能会启用基本身份验证，以便您可以使用用户名和密码身份验证运行本地集群。

由于您已启用 xpack.security，您必须创建一个 elasticsearch 密码并使用此通行证连接到它：https://www.elastic.co/guide/en/elasticsearch/reference/current/security-minimal-setup。 html#security-create-builtin-users

使用上面链接中的步骤创建一个密码，然后尝试使用用户名“elastic”和创建的密码再次连接

检查启动日志文件的上部。可能还打印了其他错误。在我的情况下，最后一行也是关于尝试加载 geoip-databases。实际根本原因是托管数据目录的路径上的磁盘空间不足。ElasticSearch 版本：7.14.0
