中文分词器下载地址 https://github.com/medcl/elasticsearch-analysis-ik

elasticsearch-analysis-ik-master.zip

安装配置apache-maven

http://mirror.bit.edu.cn/apache/maven/maven-3/3.5.4/binaries/apache-maven-3.5.4-bin.tar.gz
tar -zxvf apache-maven-3.5.4-bin.tar.gz 
mv apache-maven-3.5.4 /usr/local
cd /usr/local
ln -s  apache-maven-3.5.4 apache-maven
vim /etc/profile
export PATH=/usr/local/apache-maven/bin:$PATH

使用mvn 对elasticsearch-analysis-ik-master 进行编译

unzip elasticsearch-analysis-ik-master.zip
mv elasticsearch-analysis-ik-master /usr/local
cd /usr/local/elasticsearch-analysis-ik-master
mvn clean install -Dmaven.test.skip=true

会生成elasticsearch-analysis-ik-master/target/releases/elasticsearch-analysis-ik-6.5.0.zip

将其拷贝到es的插件目录下

mkdir /usr/local/elasticsearch/plugins/ik/
cp elasticsearch-analysis-ik-master/target/releases/elasticsearch-analysis-ik-6.5.0.zip /usr/local/elasticsearch/plugins/ik/

unzip /usr/local/elasticsearch/plugins/ik/elasticsearch-analysis-ik-6.5.0.zip

编译后会是最新版的中文分词包，对应es的6.2.4 可以去下载编译好的
