Elasticsearch 7.1.1 安装 pinyin 分词器插件

1、安装maven

安装插件前，需要用 maven 进行编译生成插件包，第一步先安装 maven

yum install -y maven

mvn -version

Apache Maven 3.0. (Red Hat 3.0.-)

Maven home: /usr/share/maven

Java version: 1.8.0_222, vendor: Oracle Corporation

Java home: /usr/lib/jvm/java-1.8.-openjdk-1.8.0.222.b10-.el7_6.x86_64/jre

Default locale: en_US, platform encoding: UTF-

OS name: "linux", version: "3.10.0-957.27.2.el7.x86_64", arch: "amd64", family: "unix"

2、下载插件包

github地址：https://github.com/medcl/elasticsearch-analysis-pinyin

下载zip包，并解压

wget https://codeload.github.com/medcl/elasticsearch-analysis-pinyin/zip/elasticsearch-analysis-pinyin-master.zip

unzip elasticsearch-analysis-pinyin-master.zip

3、修改版本号

查看pom.xml文件中的版本号，需要修改和 es 的版本相同

cd elasticsearch-analysis-pinyin-master

vim pom.xml

<elasticsearch.version>7.1.</elasticsearch.version>

4、编译

mvn clean install -Dmaven.test.skip

在当前 target/releases 目录下生成了 elasticsearch-analysis-pinyin-7.1.1.zip 包

5、安装插件

安装插件很简单，只需要解压到 es 的 plugins 目录下即可

#新建目录
mkdir /opt/elasticsearch/plugins/analysis-pinyin

#复制插件包
cd target/releases
cp elasticsearch-analysis-pinyin-7.1..zip /opt/elasticsearch/plugins/analysis-pinyin


#解压
cd /opt/elasticsearch/plugins/analysis-pinyin

unzip elasticsearch-analysis-pinyin-7.1..zip

6、重启es

../../bin/elasticsearch-plugin list

service elasticsearch restart

7、验证

登入 kibana 执行如下命令：

GET /_analyze

{

  "text": ["刘德华"],

  "analyzer": "pinyin"

}

返回结果：

{

  "tokens" : [

    {

      "token" : "liu",

      "start_offset" : ,

      "end_offset" : ,

      "type" : "word",

      "position" :

    },

    {

      "token" : "de",

      "start_offset" : ,

      "end_offset" : ,

      "type" : "word",

      "position" :

    },

    {

      "token" : "hua",

      "start_offset" : ,

      "end_offset" : ,

      "type" : "word",

      "position" :

    },

    {

      "token" : "ldh",

      "start_offset" : ,

      "end_offset" : ,

      "type" : "word",

      "position" :

    }

  ]

}
