1.更新yum等资源
sudo yum update -y
sudo rpm -ivh http://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
sudo rpm -ivh https://kojipkgs.fedoraproject.org//packages/http-parser/2.7.1/3.el7/x86_64/http-parser-2.7.1-3.el7.x86_64.rpm
sudo yum install npm sudo yum install -y git sudo yum install -y bzip2 git clone git://github.com/mobz/elasticsearch-head.git
2.将源码包下载后剪切到/bigdata目录，并改所属用户和组
sudo chown -R wang:123465 /bigdata/elasticsearch-head
3.进入到elasticsearch-head中
cd elasticsearch-head
4.编译安装
npm install
5.打开elasticsearch-head-master/Gruntfile.js，找到下面connect属性，新增hostname: '0.0.0.0',
connect: { server: { options: { hostname: '0.0.0.0', port: 9100, base: '.', keepalive: true } } }
6.编辑elasticsearch-5.4.3/config/elasticsearch.yml,加入以下内容：
http.cors.enabled: true
http.cors.allow-origin: "*"
7.运行服务
自己写一个脚本后台运行 监控页面
[......head] vi start-head.sh
8.!/bin/sh
npm run start >> .logs 2>&1 &
chmod +x start-head.sh
./start-head.sh
二、安装IK分词器
1.下载对应版本的插件 5.4.3
https://github.com/medcl/elasticsearch-analysis-ik/releases
2.首先下载es对应版本的ik分词器的zip包，上传到es服务器上，在es的安装目录下有一个plugins的目录，在这个目录下创建一个叫ik的目录然后将解压好的内容，拷贝到ik目录将ik目录拷贝到其他的es节点
yum install unzip mkdir ik cp elas...zip ik/ unzip elastic... rm -rf elas...zip mv ik /bigdata/ela.../plugins/ scp -r ik/ hadoop7:$PWD
3.重新启动所有的es
4.测试插件
创建索引名字叫news
curl -XPUT http://192.168.52.206:9200/news
创建mapping（相当于数据中的schema信息，表名和字段名以及字段的类型）
curl -XPOST http://192.168.52.206:9200/news/fulltext/_mapping -d' { "properties": { "content": { "type": "text", "analyzer": "ik_max_word", "search_analyzer": "ik_max_word" } } }'
//查询
curl -XPOST http://192.168.52.206:9200/news/fulltext/_search -d' { "query" : { "match" : { "content" : "中国" }}, "highlight" : { "pre_tags" : ["<font color='red'>", "<tag2>"], "post_tags" : ["</font>", "</tag2>"], "fields" : { "content" : {} } } }'
curl -XGET 'http://192.168.52.206:9200/_analyze?pretty&analyzer=ik_max_word' -d '联想是全球最大的笔记本厂商'
curl -XGET 'http://192.168.52.206:9200/_analyze?pretty&analyzer=ik_smart' -d '联想是全球最大的笔记本厂商'
curl -XPUT 'http://192.168.52.206:9200/iktest?pretty' -d '{ "settings" : { "analysis" : { "analyzer" : { "ik" : { "tokenizer" : "ik_max_word" } } } }, "mappings" : { "article" : { "dynamic" : true, "properties" : { "subject" : { "type" : "string", "analyzer" : "ik_max_word" } } } } }' curl -XPUT 'http://192.168.52.206:9200/iktest?pretty' -d '{ "settings" : { "analysis" : { "analyzer" : { "ik" : { "tokenizer" : "ik_max_word" } } } }, "mappings" : { "article" : { "dynamic" : true, "properties" : { "subject" : { "type" : "string", "analyzer" : "ik_max_word" } } } } }'
curl -XGET 'http://192.168.52.206:9200/_analyze?pretty&analyzer=ik_max_word' -d ‘中华人民共和国’
