Elasticsearch 7.1.1 安装 pinyin 分词器插件

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 -versionApache Maven 3.0.5 (Red Hat 3.0.5-17)
Maven home: /usr/share/maven
Java version: 1.8.0_222, vendor: Oracle Corporation
Java home: /usr/lib/jvm/java-1.8.0-openjdk-1.8.0.222.b10-0.el7_6.x86_64/jre
Default locale: en_US, platform encoding: UTF-8
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：

下载zip包，并解压

wget .zip
unzip elasticsearch-analysis-pinyin-master.zip

3、修改版本号

查看l文件中的版本号，需要修改和 es 的版本相同

cd elasticsearch-analysis-pinyin-master

l
<elasticsearch.version>7.1.1</elasticsearch.version>

4、编译

mvn clean install -st.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-7.1.1.zip /opt/elasticsearch/plugins/analysis-pinyin

#解压
cd /opt/elasticsearch/plugins/analysis-pinyin
unzip elasticsearch-analysis-pinyin-7.1.1.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" : 0,"end_offset" : 0,"type" : "word","position" : 0},{"token" : "de","start_offset" : 0,"end_offset" : 0,"type" : "word","position" : 1},{"token" : "hua","start_offset" : 0,"end_offset" : 0,"type" : "word","position" : 2},{"token" : "ldh","start_offset" : 0,"end_offset" : 0,"type" : "word","position" : 2}]
}
