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" :
    }
  ]
}
