环境配置

操作系统:Cent OS 6.5ElasticSearch:2.4.3JDK:1.7maven:3.3.9elasticsearch-analysis-ik:1.4.1

1、首先要把jdk安装好,然后下载elasticsearch-2.3.4.tar.gz

wget https://download.elastic.co/elasticsearch/release/org/elasticsearch/distribution/tar/elasticsearch/2.3.4/elasticsearch-2.3.4.tar.gz

2、解压下载好的elasticsearch-2.3.4.tar.gz

[root@localhost opt]# cd /opt/[root@localhost opt]# lselasticsearch-2.3.4.tar.gz  git-1.8.3.2.tar.gz[root@localhost opt]# tar zxvf elasticsearch-2.3.4.tar.gz

3、创建用户和用户组(elasticsearch 2.0.0版本后不能以root用户启动。)

[root@localhost opt]# groupadd elsearch[root@localhost opt]# useradd elsearch -g elsearch -p elasticsearch

4、把解压好的目录移动到/usr/local/elasticsearch

[root@localhost opt]# mv elasticsearch-2.3.4 /usr/local/elasticsearch

5、设置权限

chown -R elsearch:elsearch  /usr/local/elasticsearch

6、安装es-head插件

[root@localhost plugins]# cd /usr/local/elasticsearch/bin/[root@localhost plugins]# ./plugin –install mobz/elasticsearch-head

7、在浏览器中输入如下图所示则ES启动成功。

8、若要停止服务,则输入sh elasticsearch stop

[root@localhost opt]# cd /usr/local/elasticsearch/bin[root@localhost opt]# sh elasticsearch stop

9、安装ik中文分词首先要安装java 和 elasticsearch

(1)安装maven

[root@localhost opt]# tar zxvf apache-maven-3.3.9-bin.tar.gz [root@localhost opt]# mv apache-maven-3.3.9 /usr/local/maven[root@localhost opt]# vim /etc/profile
export PATH=$PATH:$JAVA_HOME/binexport M2_HOME=/usr/local/mavenPATH=$PATH:$JAVA_HOME/bin:$M2_HOME/bin
[root@localhost opt]# source /etc/profile

(2)安装elasticsearch-analysis-ik

[root@localhost opt]# wget -c [root@localhost opt]# unzip master.zip[root@localhost opt]# cd elasticsearch-analysis-ik-master/  [root@localhost elasticsearch-analysis-ik-master]# cp -Rf config/* ik /usr/local/elasticsearch/config/[root@localhost elasticsearch-analysis-ik-master]# mvn package[root@localhost elasticsearch-analysis-ik-master]# /usr/local/elasticsearch/bin/plugin --install analysis-ik --url file:///alidata/download/elasticsearch-analysis-ik-master/target/releases/elasticsearch-analysis-ik-1.4.1.zip

(3)修改elasticsearch.yml,在该文件后面添加下面的内容:

[root@localhost ~]# cd /usr/local/elasticsearch/config[root@localhost config]# vim elasticsearch.ymlindex:  analysis:                       analyzer:            ik:          alias: [ik_analyzer]          type: org.elasticsearch.index.analysis.IkAnalyzerProvider      ik_max_word:          type: ik          use_smart: false      ik_smart:          type: ik          use_smart: trueindex.analysis.analyzer.default.type: ik

(4)重新启动elasticsearch

[root@localhost config]# /usr/local/elasticsearch/bin/elasticsearch -d

(5) ik分词测试,创建一个索引,名为index

[root@localhost config]# curl -XPUT http://localhost:9200/index

为索引index创建mapping

[root@localhost config]# curl -XPOST http://localhost:9200/index/fulltext/_mapping -d'{    "fulltext": {             "_all": {            "analyzer": "ik"        },        "properties": {            "content": {                "type" : "string",                "boost" : 8.0,                "term_vector" : "with_positions_offsets",                "analyzer" : "ik",                "include_in_all" : true            }        }    }}'

测试

[root@localhost config]# curl 'http://localhost:9200/index/_analyze?analyzer=ik&pretty=true' -d '{"text":"www.acp.com"}'

显示结果如下:

{  "tokens" : [ {    "token" : "text",    "start_offset" : 4,    "end_offset" : 8,    "type" : "ENGLISH",    "position" : 1  }, {    "token" : "www.acp.com",    "start_offset" : 11,    "end_offset" : 24,    "type" : "LETTER",    "position" : 2  }, {    "token" : "www",    "start_offset" : 11,    "end_offset" : 14,    "type" : "acp",    "position" : 3  }, {    "token" : "acp",    "start_offset" : 15,    "end_offset" : 20,    "type" : "ENGLISH",    "position" : 4  }, {    "token" : "com",    "start_offset" : 21,    "end_offset" : 24,    "type" : "ENGLISH",    "position" : 5  }, {
