Kibana 停止工作，现在服务器没有准备好，尽管 kibana.service 启动良好

Question

我的 Ubuntu (4.4.0-142-generic #168-Ubuntu SMP) 没有任何重大系统更新，Kibana 7.2.0 停止工作。我仍然可以使用 sudo systemctl start kibana.service 启动服务，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."}

然而，当我在我的客户端机器上访问 http://srv003:5601/ 时，我一直只看到（甚至在等待 20 分钟后）：

Kibana server is not ready yet

在服务器 srv003 本身，我看到

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 似乎真的在那个端口上侦听并且出于测试目的禁用了防火墙：

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 的日志中也没有任何可疑的：

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 还在运行运行。相应的日志文件中没有关于 Kibana 的有趣内容：

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]

现在我运行有点没办法了，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

看起来如果 Kibana 进入描述的未定义状态，则需要简单地重新启动计算机。对于其他服务运行.

的（虚拟或物理）机器来说，这当然是不可接受的
