Answer 1

问题可能是由于 kibana 无法在本地访问 elasticsearch 导致的。

我认为您已通过添加新行在elasticsearch.yml中出于安全目的启用了xpack.security插件：

xpack.security.enabled : true

如果是这样，您需要取消注释 kibana.yml 上的两行：

#elasticsearch.用户名：“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

Answer 2

检查

$systemctl status elasticsearch

。我猜你的elasticsearch服务还没有启动。

Answer 3

我想有很多因素需要检查，首先请进入您安装 Kibana 的 config 目录并检查

kibana.yml

旁边的

sudo vi kibana.yml

并检查 Kibana 尝试连接的弹性服务器端口（默认值为 9200）。 这里是默认配置的示例。

将此配置与您的需求匹配后，转到您为 Kibana 服务保存的脚本文件，并检查

[unix]

部分是否需要首先激活弹性服务，以及是否未添加 Elasticserver make 的“必需”部分确保弹性服务器在运行 Kibana 作为服务之前已启动并运行，您还可以通过转到 Kibana 的 bin 目录并为 Kibana 提供午餐来将 Kibana 作为 shell 提供午餐。

Answer 4

你可以检查一下

systemctl 状态 kibana -l 猫 /var/log/elasticsearch/elasticsearch.log | grep -i -E“错误|警告”

之后

systemctl 重新启动elasticsearch

你可以再试一次。
