Answer 1

我猜有很多因素需要检查，首先请进入您安装Kibana的配置目录，通过sudo vi kibana.yml检查kibana.yml，并检查Kibana尝试连接的elastic服务器的端口(默认为9200)。Here是默认配置的一个示例。

将此配置与您的需求相匹配后，转到为Kibana服务保存的脚本文件，并检查[unix]部分，如果它需要首先激活弹性服务，如果您没有为Elasticserver添加“必需”部分，请在运行Kibana作为服务之前确保弹性服务器已启动并运行，您也可以通过转到Kibana的bin控制器并运行Kibana来将Kibana作为shell。

Answer 2

检查$systemctl status elasticsearch。我猜你的elasticsearch服务还没有启动。

Answer 3

也许这个问题是由于kibana无法在本地访问elasticsearch造成的。

我认为您已经在elasticsearch.yml上为安全目的启用了xpack.security插件，添加了新的一行：

xpack.security.enabled : true

如果是这样，您需要在kibana.yml上取消注释这两行：

#elasticsearch.username："kibana“

#elasticsearch.password：“通过”

elasticsearch.username = "kibana_system" 
elasticsearch.password = "your-password"

保存更改后，重新启动kibana服务：

sudo sservice kibana restart
