es 版本使用 7.0.0 设置了 xpack.security.enabled: true xpack.security.transport.ssl.enabled: true 启动 es之后执行 ./elasticsearch-setup-passwords interactive ERROR: X-Pack Security is not available.

作者回复: ES下载有多个版本。我不记得7.0是否默认已经带了x-pack了。7.1肯定是默认带了xpack。如果你下载的oss版本，默认也是不带xpack的。你可以通过安装plugin的方式，将x-pack安装后，再启动集群

老师如何用python的request 请求 http://172.168.1.2:9200 带用户名和密码

作者回复: 如果是用标准http request 那就是在http header上加上用户名和密码的信息。如果是用了python库，可以具体查看api文档 https://www.cnblogs.com/xiao987334176/p/10130712.html

不知道是版本的问题还是老师本身就用的付费版，我这里在只设定了 xpack.security.enabled=true 之后会报错提示还需要设置 xpack.security.transport.ssl.enabled=true 才可以

作者回复: 下面这个配置是保护9300端口的。在我课程7.1中不设置也是可以运行的。不知道是不是在新版本中做了更加严格的要求

作者回复: 没碰到这样的情况，要确保这个时候es是正常工作的。从日志看是timeout了。你可以登录到kibana界面中，通过amin账户去重设这个apm用户的密码

你好，老师：我配置x-pack之后，每次生成密码都会报错，请问是什么原因呢？ [@es-master1 ~]# /usr/local/elasticsearch/bin/elasticsearch-setup-passwords interactive --verbose Trying user password change call http://10.13.65.162:9200/_security/user/apm_system/_password?pretty { "error" : { "root_cause" : [ { "type" : "status_exception", "reason" : "Cluster state has not been recovered yet, cannot write to the [null] index" } ], "type" : "status_exception", "reason" : "Cluster state has not been recovered yet, cannot write to the [null] index" }, "status" : 503 } Unexpected response code [503] from calling PUT http://10.13.65.162:9200/_security/user/apm_system/_password?pretty Cause: Cluster state has not been recovered yet, cannot write to the [null] index Possible next steps: * Try running this tool again. * Try running with the --verbose parameter for additional messages. * Check the elasticsearch logs for additional error details. * Use the change password API manually. ERROR: Failed to set password for user [apm_system]. [@es-master1 ~]#

作者回复: es启动了吗？

老师你好，我想请教一下，X-pack只在7.0上免费吗？6.0可以用吗？如果不可以，数据从6.0迁移到7.0简单吗？

作者回复: 6.x貌埃不支持basic版。先升级到6.8 就只是做滚动升级至7.x 否则需要full restart

老师辛苦了，谢谢您辛苦录制的课程，让一个刚做运维工作不久的我,深深喜欢上了Elasticsearch这个开源产品，每天都能学习,并且有新的收获，在这里也写几点自己个人的观点,首先是对日志收集展示方面的内容没有看到,其次是检测报警这个方面希望老师有时间能讲解下.

作者回复: alerting属于收费功能，有简单的介绍。xpack相关的章节。日志也会有一节做相关的介绍

集群开启xpack后，Https是不是必须开启?

作者回复: 建议要做全链路加密，否则有安全风险
