1、官方文档：[https://www.elastic.co/guide/cn/elasticsearch/guide/current/foreword\_id.html][https_www.elastic.co_guide_cn_elasticsearch_guide_current_foreword_id.html]

下载ElasticSearch：[https://www.elastic.co/downloads/elasticsearch][https_www.elastic.co_downloads_elasticsearch]

2、elasticsearch的启动和配置：[https://blog.csdn.net/u014073556/article/details/80666393][https_blog.csdn.net_u014073556_article_details_80666393]

3、著名的开源爬虫程序SolrNutchGrubAperture

4、启动程序是哪个？讲真的bin目录下太多文件，作为新手的我还真不知道点哪一个 elasticsearch.bat

5、如何修改端口：和大多数apache项目一样 elasticsearch 的配置文件和日志文件在config文件夹中elasticsearch.yml

默认端口 9200

#设置本机端口
    network.host: localhost
    http.port: 9200
    
    #磁盘不足警告
    cluster.routing.allocation.disk.threshold_enabled: false
    #cluster.routing.allocation.disk.watermark.low: 30gb
    #cluster.routing.allocation.disk.watermark.high: 20gb
    
    #跨域
    http.cors.enabled: true
    http.cors.allow-origin: "*"

6、最终效果：

# **elasticsearch-head** #

**7、elasticsearch-head安装**

elasticsearch-head是一个用于管理Elasticsearch的web前端插件

https://github.com/mobz/elasticsearch-head

运行环境准备NodeJS,Grunt

**npm install -g grunt-cli**

**git clone git://github.com/mobz/elasticsearch-head.git**

**cd elasticsearch-head**

**npm install**

修改elasticsearch.yml，增加跨域的配置(需要重启es才能生效)

http.cors.enabled: true

http.cors.allow-origin: "\*"

编辑elasticsearch-head/Gruntfile.js，修改服务器监听地址，connect节点增加hostname属性，将其值设置为\*

connect: \{

server: \{

options: \{

hostname:'\*',

port: 9100,

base: '.',

keepalive: true

编辑elasticsearch-head/\_site/app.js, 修改默认es地址为http://[http://localhost][http_localhost]:9200/, 也可以不修改。

启动

**npm run start**

**浏览器打开**[**http://**][http][localhost][http_localhost][**:9100/**][http]

** **

**注意下列信息需要在****Logstash****连接ES上后才可以展现。**

ES数据默认存储位置：D:\\xxxxxxx\\elasticsearch-5.4.3\\data

ElasticSearch可视化工具kibana（可以监听nginx等日志）
