Win10 主机上的 Centos VM 来宾。尝试遵循x-pack 的安装指南（并从培训课程中逐步完成）。ES 和 K 运行良好，但是一旦安装了 x-pack 插件，kibana 将启动（并抱怨 ES 丢失 - 这很好），然后弹性搜索启动并立即失败。它看起来与3相同的错误，但在本地 VM 中，而不是在生产设置中。这是日志的尾部：

试试看：

  1. 打开 config/elasticsearch.yml 文件
  2. 更改 xpack 配置行

xpack.security.enabled: false xpack.graph.enabled: false xpack.watcher.enabled: false

好吧，因为日志包含

Caused by: java.nio.file.AccessDeniedException:

问题可能是用户权限。这个目录的所有者是谁？

/etc/elasticsearch/x-pack

什么ls -l /etc/elasticsearch/x-pack给你一个输出？

如果您具有 sudo 权限或具有 root 访问权限，您可能只是更改此目录的所有权。

问题在于您用于安装 elasitcsearch 和 x-pack 的用户帐户。确保您使用相同的帐户并拥有正确的权限！

您可能希望使用 chown 授予访问权限。
