centos7系统下elasticsearch7.5.1集群安装elasticsearch-jieba-plugin 7.4.2 和analysis-kuromoji 日语分词器

elasticsearch7.5.1集群安装elasticsearch-jieba-plugin 7.4.2 和analysis-kuromoji 日语分词器

安装插件需要在集群的其中一个节点安装后重启es程序，没有问题后拷贝到其他节点重启后生效

1.elasticsearch-jieba需要使用gradle进行编译
# 安装gradle
下载gradle的二进制文件

wget https://services.gradle.org/distributions/gradle-6.3-bin.zip
cd /usr/local/elk

# 修改环境变量将gradle加入环境变量中
# vim /etc/profile

export GRADLE_HOME=/usr/local/elk/gradle-6.3/
export PATH=$GRADLE_HOME/bin:$PATH

screen -S gradle

# 编译生成jieba分词插件
[elasticsearch@sz_ms_influenex_es_dev01_17_19 elasticsearch-jieba-plugin-7.4.2]$ gradle pz

Welcome to Gradle 6.3!

Here are the highlights of this release:
 - Java 14 support
 - Improved error messages for unexpected failures

For more details see https://docs.gradle.org/6.3/release-notes.html

Starting a Gradle Daemon (subsequent builds will be faster)

Deprecated Gradle features were used in this build, making it incompatible with Gradle 7.0.
Use '--warning-mode all' to show the individual deprecation warnings.
See https://docs.gradle.org/6.3/userguide/command_line_interface.html#sec:command_line_warnings

# 将最终编译生成的elasticsearch-jieba-plugin-7.4.2.zip拷贝到es插件目录中
cp /usr/local/elk/elasticsearch-7.5.1/plugins/elasticsearch-jieba-plugin-7.4.2/build/distributions/elasticsearch-jieba-plugin-7.4.2.zip /usr/local/elk/elasticsearch-7.5.1/plugins/
cd /usr/local/elk/elasticsearch-7.5.1/plugins/
unzip -d jieba elasticsearch-jieba-plugin-7.4.2.zip


# 修改jieba配置，因为没有最新的 jieba 7.5.1 插件，直接修改配置即可
# cat /usr/local/elk/elasticsearch-7.5.1/plugins/jieba/plugin-descriptor.properties

# 重新启动elasticsearch

[root@sz_ms_influenex_es_dev01_17_19 ~]# /usr/local/elk/elasticsearch-7.5.1/bin/elasticsearch-plugin list
jieba


# 测试
[root@sz_ms_influenex_es_dev02_17_20 elasticsearch-7.5.1]# curl -H "Content-Type: application/json" -u elastic:pass -XPOST http://10.10.17.19:9200/_analyze -d '{"analyzer" : "jieba_index", "text" : "你好，世界，很高兴认识你！"}'

# 将jieba这个插件拷贝到其他节点

scp -P 2016 -r jieba 10.10.17.21:/usr/local/elk/elasticsearch-7.5.1/plugins/

# 注意修改文件权限
chown -R elasticsearch.elasticsearch /usr/local/elk/elasticsearch-7.5.1/

# 在elasticsearch用户下重启es
su elasticsearch

curl -H "Content-Type: application/json" -u elastic:pass -XPOST http://10.10.17.20:9200/_analyze -d '{"analyzer" : "jieba_index", "text" : "你好，世界，很高兴认识你！"}'
curl -H "Content-Type: application/json" -u elastic:pass -XPOST http://10.10.17.21:9200/_analyze -d '{"analyzer" : "jieba_index", "text" : "你好，世界，很高兴认识你！"}'



二、analysis-kuromoji 日语分词器的安装
# 下载分词器
cd /usr/local/elk/elasticsearch-7.5.1/plugins
wget https://artifacts.elastic.co/downloads/elasticsearch-plugins/analysis-kuromoji/analysis-kuromoji-7.5.1.zip
unzip -d kuromoji analysis-kuromoji-7.5.1.zip
rm -f analysis-kuromoji-7.5.1.zip

# 切换到elasticsearch用户，重启es程序
su elasticsearch

# 分别拷贝到其他节点并且重启
# 注意修改文件权限
chown -R elasticsearch.elasticsearch /usr/local/elk/elasticsearch-7.5.1/
