elasticsearch - 尽管kibana.service正常启动，但Kibana停止工作，现在服务器未准备就绪

Question

没有对我的Ubuntu(4.4.0-142-generic #168-Ubuntu SMP)进行任何重大系统更新，Kibana 7.2.0停止工作。我仍然可以使用sudo systemctl start kibana.service启动该服务，并且相应的状态看起来很好。只有警告，没有错误，这似乎不是问题所在:

# sudo systemctl status kibana.service 
● kibana.service - Kibana
   Loaded: loaded (/etc/systemd/system/kibana.service; enabled; vendor preset: enabled)

Jul 10 09:56:36 srv003 kibana[14856]: {"type":"log","@timestamp":"2019-07-10T07:56:36Z","tags":["warning","task_manager"],"pid":14856,"message":"The task maps_telemetry \"Maps-maps_telemetry\" is not cancellable."}

但是，当我在客户端计算机上访问 http://srv003:5601/时，我仍然只能看到(即使在等待20分钟之后):

Kibana server is not ready yet

在服务器 srv003本身上，我看到了

me@srv003:# curl -XGET http://localhost:5601/status -I
curl: (7) Failed to connect to localhost port 5601: Connection refused

这很奇怪，因为Kibana似乎真的在该端口上监听，并且防火墙出于测试目的而被禁用:

root@srv003# sudo lsof -nP -i | grep 5601
node      14856        kibana   18u  IPv4 115911041      0t0  TCP 10.0.0.72:5601 (LISTEN)
root@srv003# sudo ufw status verbose
Status: inactive

kibana.service的日志中也没有可疑的东西:

root@srv003:/var/log# journalctl -u kibana.service | grep -A 99 "Jul 10 10:09:14"
Jul 10 10:09:14 srv003 systemd[1]: Started Kibana.
Jul 10 10:09:38 srv003 kibana[14856]: {"type":"log","@timestamp":"2019-07-10T08:09:38Z","tags":["warning","task_manager"],"pid":14856,"message":"The task maps_telemetry \"Maps-maps_telemetry\" is not cancellable."}

我的Elasticsearch仍在运行。在有关Kibana的相应日志文件中没有有趣的事情:

root@srv003:/var/log# cat elasticsearch/elasticsearch.log  |grep kibana
[2019-07-10T09:46:25,158][INFO ][o.e.c.m.MetaDataIndexTemplateService] [srv003] adding template [.kibana_task_manager] for index patterns [.kibana_task_manager]

现在我的选项已经用光了，希望有人能给我另一个提示。

编辑:我没有安装任何Kibana插件。

Answer 1

如果Kibana进入描述的未定义状态，则需要简单地重新启动计算机。对于运行其他服务的(虚拟或物理)机器，这当然是 Not Acceptable 。
