Elasticsearch安裝配置

環境配置

操做系統：Cent OS 6.5
ElasticSearch：2.4.3
JDK：1.7
maven:3.3.9
elasticsearch-analysis-ik:1.4.1

一、首先要把jdk安裝好，而後下載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

二、解壓下載好的elasticsearch-2.3.4.tar.gz

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

三、建立用戶和用戶組(elasticsearch 2.0.0版本後不能以root用戶啓動。)

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

四、把解壓好的目錄移動到/usr/local/elasticsearch

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

五、設置權限

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

六、安裝es-head插件

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

七、在瀏覽器中輸入http://localhost:9200，http://localhost:9200/_plugin/head/以下圖所示則ES啓動成功。

八、若要中止服務，則輸入sh elasticsearch stop

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

九、安裝ik中文分詞，首先要安裝java 和 elasticsearch

(1)安裝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/bin
export M2_HOME=/usr/local/maven
PATH=$PATH:$JAVA_HOME/bin:$M2_HOME/bin

[root@localhost opt]# source /etc/profile

(2)安裝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，在該文件後面添加下面的內容：

[root@localhost ~]# cd /usr/local/elasticsearch/config
[root@localhost config]# vim elasticsearch.yml
index:
  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: true
index.analysis.analyzer.default.type: ik

(4)從新啓動elasticsearch

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

(5) ik分詞測試，建立一個索引，名爲index

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

爲索引index建立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
            }
        }
    }
}'

測試

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

顯示結果以下：

{
  "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
  }, {
