Elasticsearch Kibana Beats Logstash X-Pack - hello world

首先es系列虽然是开源的，但是有些组件并不是免费的，相应的价格请参照如下：
https://www.elastic.co/subscriptions
另外es也提供云端的服务，价格参照如下：
Elastic Cloud Standard Pricing Calculator：https://www.elastic.co/cloud/as-a-service/pricing

本文旨在搭建一个初始版本的elastic search栈，包括Elasticsearch Kibana （Beats,可能暂时不会包括） Logstash（可能暂时不搭建，因为暂时采用从mongoDB用mongo-connector自动同步数据） X-Pack, Angular4

Angular4+es例子工程参考：

https://github.com/junglestory/elasticsearch-angular

https://github.com/junglestory/elasticsearch-sample-books

（注，ES官网安装es，xpack等提供msi安装版的安装文件，安装过程应该相对简单些，但是因后续生产环境不是windows，是类linux，所以此处采用类linux方式）

1，Download Elasticsearch and install

下载zip包，找个安装目录解压完即安装完毕：https://www.elastic.co/cn/downloads/elasticsearch

这篇文章讲解操作es的简单的基本命令，比如idex增删改查，filter，聚合查询等
Elasticsearch基础教程：http://blog.csdn.net/cnweike/article/details/33736429
《注：本文当执行curl -XPUT 'localhost:9200/customer?pretty'在powershell时报错，请参考另一篇文章《Powershell原生支持的cURL - Invoke-WebRequest 及与 cURL的使用区别》，改成相应的Invoke-WebRequest命令执行即可》，或者在Chrome下扩展插件，Postman Rest是个不错的选择

2，Download Kibana and install

Install Kibana on Windows
Kibana can be installed on Windows using the .zip package：https://www.elastic.co/guide/en/kibana/current/windows.html

Download Kibana，Installation Steps and Open config/kibana.yml in an editor：https://www.elastic.co/downloads/kibana

3，Install X-Pack

Security, monitoring, and more for Elasticsearch and Kibana

Install X-Pack：https://www.elastic.co/cn/downloads/x-pack#ga-release

Installing X-Pack：https://www.elastic.co/guide/en/x-pack/current/installing-xpack.html#xpack-package-installation

按照官网，执行如下命令提示connection timed out，可能是内网原因要设置proxy，各种设置后也没好用，浪费时间暂时不捣鼓了，看官网资料还可以采用offline方式安装，即下载x-pack安装文件包后本地安装

bin/elasticsearch-plugin install x-pack

bin/kibana-plugin install x-pack

https://www.elastic.co/guide/en/x-pack/current/installing-xpack.html#xpack-package-installation

The X-Pack installation scripts require direct internet access to download and install X-Pack. If your servers don’t have internet access, 

you can manually download the X-Pack zip file and transfer it to a temporary directory on the offline machines. The plugins for Elasticsearch, 

Kibana and Logstash are all included in a single zip file. 

For more information about installing X-Pack on offline machines, see the product-specific X-Pack installation instructions

https://artifacts.elastic.co/downloads/packs/x-pack/x-pack-5.6.2.zip

offline: 

elasticsearch-plugin install file:///path/to/file/x-pack-5.6.0.zip

kibana-plugin install file:///path/to/file/x-pack-5.6.0.zip

C:\newsavedata\kibana-5.6.0-windows-x86\bin>kibana-plugin install file:///newsavedata/x-pack-5.6.0.zip

//安装完x-pack后，浏览器访问es或者代码访问es，可能会出现权限认证的问题，需要配置权限在es，因是hello world，所以采用匿名认证方式：

How To: Configure Elasticsearch Security With X-Pack

4, You’re "go" for launch

#enable automatically create index, elasticsearch增加自动创建索引功能
#action.auto_create_index: .security,.monitoring*,.watches,.triggered_watches,.watcher-history*

//本来要配置es和x-pack的自动创建索引功能，按照官网或者网上资料配置后，启动es时抛异常，根本起不来，暂时没找到原因,fuck了

org.elasticsearch.bootstrap.StartupException: ElasticsearchException[Failed to load plugin class [org.elasticsearch.xpack.XPackPlugin]]; 

nested: InvocationTargetException; nested: IllegalArgumentException[the [action.auto_create_index] setting value 

[.security,.monitoring*,.watches,.triggered_watches,.watcher-history*] is too restrictive. disable [action.auto_create_index] or set it to [.security,.security-6]];at org.elasticsearch.bootstrap.Elasticsearch.init(Elasticsearch.java:136) ~[elasticsearch-5.6.0.jar:5.6.0]

Start Elasticsearch…
bin/elasticsearch
Start Kibana…
bin/kibana
//启动kibana后，提示[license][xpack] Imported license information from Elasticsearch for [data] cluster: mode: trial | status: active | expiry date: 2017-10-27T08:53:04+08:00

因为是收费的组件，试用3个月

5, Open Kibana

#安装Kibana时出现：
#default index Error: Please specify a default index pattern 
#http://localhost:5601/
#解决的方法：
#将配置文件kibana.yml中下面一项的配置放开（#注释符去掉）即可：
#kibana.index: ".kibana"
kibana.index: ".kibana"

books

//当在Index pattern advanced options下面的文本框里填上之前create过的某一个index，即可出现【create】按钮

本地测试时，在angular里用js访问es，提示跨域访问失败，解决方案如下：https://segmentfault.com/q/1010000002590652

in elasticsearch.yml file

http.cors.allow-origin: "/.*/"
http.cors.enabled: true
