【问题讨论】：

你好，马蒂。您应该直接查看 kibana 日志，从中可以找到更多信息。 elasticsearch 真的启动并运行了吗？

标签： elasticsearch kibana

【解决方案1】：

我想有很多因素需要检查，首先请到你安装 Kibana 的 config 目录，检查 kibana.yml by sudo vi kibana.yml 并检查 Kibana 尝试连接的弹性服务器的端口连接（默认为 9200）。 Here 是默认配置的示例。

在将此配置与您的需要匹配后，转到您为 Kibana 服务保存的脚本文件并检查 [unix] 部分是否需要先激活弹性服务，如果您没有添加“必需”部分在将 Kibana 作为服务运行之前，Elasticserver 确保弹性服务器已启动并运行，您还可以通过转到 Kibana 的 bin 主管并午餐 Kibana 来午餐 Kibana 作为 shell。

【解决方案2】：

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

【讨论】：

这可能不是这种情况，可能弹性服务器已经启动并运行，而 Kibana 还无法配置服务器。

【解决方案3】：

问题可能是由于kibana无法在本地访问elasticsearch。

我认为您已通过添加新行在 elasticsearch.yml 启用 xpack.security 插件以实现安全目的：

xpack.security.enabled : true

如果是这样，您需要取消注释 kibana.yml 上的两行：

#elasticsearch.username: "kibana"

#elasticsearch.password：“通过”

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

保存更改后，重启 kibana 服务：

sudo sservice kibana restart
