elasticsearch - 为什么 Kibana Node 服务器无法启动？

Question

我刚刚从 5.6.4 升级到 Elasticsearch 和 Kibana 6.0.1，但无法让 Kibana 服务器运行。该服务似乎正在运行，但没有任何东西绑定(bind)到端口，我在日志中看不到任何错误。

验证我正在运行的版本:

root@my-server:/var/log# /usr/share/kibana/bin/kibana --version
6.0.1

检查服务状态:

root@my-server:/var/log# sudo service kibana start
root@my-server:/var/log# sudo service kibana status
● kibana.service - Kibana

确认 ES 已启动并运行:

root@my-server:/var/log# curl -u elastic:"mypassword" http://my-
server:9200/
{
  "name" : "vf9xM-O",
  "cluster_name" : "my-server",
  "cluster_uuid" : "pdwwLfCOTgehc_5B8oB-8g",
  "version" : {
    "number" : "6.0.1",
    "build_hash" : "601be4a",
    "build_date" : "2017-12-04T09:29:09.525Z",
    "build_snapshot" : false,
    "lucene_version" : "7.0.1",
    "minimum_wire_compatibility_version" : "5.6.0",
    "minimum_index_compatibility_version" : "5.0.0"
  },
  "tagline" : "You Know, for Search"
}

当我尝试对 Kibana 节点服务器进行 CURL 时(根据配置，它应该在 5601 上运行):

root@my-server:/var/log# curl 'localhost:5601'
curl: (7) Failed to connect to localhost port 5601: Connection refused 

事实上，当我列出开放端口时，我看到了很多东西，但在 5601 上什么也没有:

我不确定还有什么可以尝试对 Kibana 进行故障排除，任何想法都非常感谢!

好吧，我不太确定为什么，但是在我重新启动机器后这似乎起作用了:

root@my-server:~# sudo reboot

一分钟后，我通过 SSH 重新登录，瞧:

root@my-server:~# netstat -ntlp | grep LISTEN

¯_(ツ)_/¯
