kibana页面报错：Config: Request failed with status code

前提：

kibana 6.2.4 升级 6.4.2 完成升级后首次打开kibana页面。

升级过程详见： https://blog.51cto.com/michaelkang/2298677

报错内容：

浏览器打开kibana页面后:

左上角提示：
Help us improve the Elastic Stack by providing basic feature usage statistics? We will never share this data outside of Elastic. Read more

点击 yes or no  报错如下：

Config: Request failed with status code: 503

详细报错内容：
Error: Request failed with status code: 503

排查步骤：

打开浏览器工程模式查看浏览器返回错误信息：

{statusCode: 503, error: "Service Unavailable",

 message: "Automatic index creation failed",…} 《== 核心报错内容

code: "ES_AUTO_CREATE_INDEX_ERROR"
error: "Service Unavailable"
message: "Automatic index creation failed"
statusCode: 503

以上报错信息基本可以确定是集群不能自动创建索引导致的，先临时打开试一下。

临时开启允许es集群允许创建索引

PUT _cluster/settings
{
    "transient" : 
        {
      "action.auto_create_index": "true"
        }
}

然后点击 yes or no都将不会再报错 ! 问题解决。
