安装x-pack会停止运行弹性搜索

Win10主机上的Centos VM guest虚拟机。试图按照installation guide进行x-pack（并从training course开始逐步执行）。 ES和K运行良好，但是一旦安装了x-pack插件，kibana将启动（并且抱怨ES丢失 - 这很好），然后弹性搜索开始并立即失败。它看起来像3一样的错误，但在本地虚拟机中，而不是生产设置。这里的日志尾部：安装x-pack会停止运行弹性搜索

好因为日志包含

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

ls -l /etc/elasticsearch/x-pack给你什么输出？

如果您具有sudo权限或具有root用户访问权限，则可以更改此目录的所有权。

谢谢！这是肯定的一步。 system_key文件是：-rw -------。 1 root root 128 Dec 9 16:29 system_key' so chmod 604 on the file to get read rights for elastic，and the service was able to start。默认的用户帐户尚未登录，但生病进一步审查正确的权限。这当然有助于解决主要问题 –

由于这是一个关键，最好使用'sudo chown elastic：elastic system.key'将所有权更改为弹性。大多数安全程序检查权限集。我会建议不要给别人一个阅读权限。这应该适合你。 HTH – cinhtau

了解，并会验证。 chmod是为了证明问题所在......然而，现在有了'太多的本地重定向'，因此可能需要更改我的平台以允许更多节点进行故障排除。 –

尝试一下：

打开配置/ elasticsearch.yml文件
变化xpack配置行

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

问题在于您用来安装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来执行此操作！

您可能想要使用chown授予访问权限。
