Kibana将无法连接到Elasticsearch在亚马逊的Elasticsearch服务 [英] Kibana won't connect to Elasticsearch on Amazon's Elasticsearch Service

问题描述

从主办我自己Elastiscsearch集群亚马逊Elasticsearch服务切换后，  我Kibana仪表板（版本4.0.2和4.1.2）将不会加载和我收到的kibana.log以下错误：

After switching from hosting my own Elastiscsearch cluster to Amazon's Elasticsearch Service, my Kibana dashboards (versions 4.0.2 and 4.1.2) won't load and I'm receiving the following error in kibana.log:

{
  "name": "Kibana",
  "hostname": "logs.example.co",
  "pid": 8037,
  "level": 60,
  "err": {
    "message": "Not Found",
    "name": "Error",
    "stack": "Error: Not Found\n    at respond (\/srv\/kibana\/kibana-4.1.2-linux-x64\/src\/node_modules\/elasticsearch\/src\/lib\/transport.js:235:15)\n    at checkRespForFailure (\/srv\/kibana\/kibana-4.1.2-linux-x64\/src\/node_modules\/elasticsearch\/src\/lib\/transport.js:203:7)\n    at HttpConnector.<anonymous> (\/srv\/kibana\/kibana-4.1.2-linux-x64\/src\/node_modules\/elasticsearch\/src\/lib\/connectors\/http.js:156:7)\n    at IncomingMessage.bound (\/srv\/kibana\/kibana-4.1.2-linux-x64\/src\/node_modules\/elasticsearch\/node_modules\/lodash-node\/modern\/internals\/baseBind.js:56:17)\n    at IncomingMessage.emit (events.js:117:20)\n    at _stream_readable.js:944:16\n    at process._tickCallback (node.js:442:13)"
  },
  "msg": "",
  "time": "2015-10-14T20:48:40.169Z",

}

不幸的是，这个错误是不是非常有帮助。我认为这是一个包裹HTTP 404，但对于的什么的？

我如何可以连接Kibana安装到亚马逊的Elasticsearch服务？

How can I connect a Kibana install to Amazon's Elasticsearch Service?

推荐答案

这里有一些事情使用亚马逊的Elasticsearch服务时，要记住：

Here are a some things to keep in mind when using Amazon's Elasticsearch Service:

1. 修改的访问策略采取的时间非确定性量。我发现它的好，至少等待15分钟后，状态不再是处理，使政策变化之后。

1. Modifications to the access policies take a non-deterministic amount of time. I've found that it's good to wait at least 15 minutes after the status is no longer "processing" after making policy changes.

它监听80端口的HTTP请求，而不是标准的端口9200。请确保您的 elasticsearch_url 配置指令反映了这一点，如：

It listens on port 80 for HTTP requests and not the standard port 9200. Be sure that your elasticsearch_url configuration directive reflects this, e.g.:

elasticsearch_url： http://es.example.co:80

elasticsearch_url: "http://es.example.co:80"

这很可能是你的Kibana实例将不会有必要的权限，以创建，它需要向您展示一个仪表板的指数 - 这是对问题的根源。退房指标上Elasticsearch域和寻找一个匹配 kibana_index config伪线（例如，通过的 http://es.example.co/_cat/indices ）。

It's very likely that your Kibana instance will not have the necessary permissions to create the index that it needs to show you a dashboard -- this is towards the root of the issue. Check out the indexes on the Elasticsearch domain and look for a line that matches the kibana_index config directive (e.g. via http://es.example.co/_cat/indices).

例如，如果你的 kibana_index 指令是值 .kibana-4 ，如果你不看到如下一行：

for instance, if your kibana_index directive is the value is .kibana-4, if you don't see a line like the following:

green open .kibana-4           1 1      3 2  30.3kb  17.2kb

那么你的Kibana指数无法创建它所需要的指数。如果你去到仪表板的Elasticsearch服务于亚马逊和点击Kibana链接，它可能会创建一个 .kibana-4 索引你。

您可以在现有Kibana的配置指定该索引，你应该看到下一个点。

You can specify this index in your existing Kibana's configuration and you should see the next point.

您现有的Kibana安装可能会需要通过头认证：

1. Your existing Kibana install will likely require authentication via the header:

Kibana：Authorization头需要'凭证'参数。 Authorization头需要签名的参数。 Authorization头需要SignedHeaders'参数。 Authorization头要求的存在无论是X-AMZ-日期或日期标题。

Kibana: Authorization header requires 'Credential' parameter. Authorization header requires 'Signature' parameter. Authorization header requires 'SignedHeaders' parameter. Authorization header requires existence of either a 'X-Amz-Date' or a 'Date' header.

您可以在Kibana配置这一点，可以看到href="http://docs.aws.amazon.com/general/latest/gr/signing_aws_api_requests.html" rel="nofollow">签署API请求一般。

You can configure this in Kibana and can see the general signing API request documentation for more help.

值得一提的是，该错误消息是reportably更好Kibana 4.2，但因为这是在测试阶段，亚马逊的Elasticsearch服务很是最近发布的，上面应该是在调试有帮助的。

It's worth noting that the error messaging is reportably better in Kibana 4.2, but as that's in beta and Amazon's Elasticsearch Service was very recently released, the above should be helpful in debugging.
