Elasticsearch安装ik分词器

关于Docker安装Elasticsearch和Kibana请参考：https://www.jianshu.com/p/804fe0fa6702

ik分词器github地址：https://github.com/medcl/elasticsearch-analysis-ik/releases/，选择与Elasticsearch相同的版本，下载zip包。

进入到Docker挂载Elasticsearch的外部plugins文件夹，我的是

 cd /usr/local/app/elasticsearch/plugins

没有安装过lrzsz命令的请先安装lrzsz

yum -y install lrzsz

新建并进入ik文件夹，将.zip文件上传到ik文件夹下：

mkdir ik
cd ik

输入rz，然后回车，上传.zip文件

安装unzip命令：

yum install -y unzip

解压压缩包

unzip elasticsearch-analysis-ik-7.10.1.zip

退出ik文件夹，并修改ik文件夹权限可读可写：

[root@localhost ik]# cd ..
[root@localhost plugins]# chmod -R 777 ik/
[root@localhost plugins]# cd ik
[root@localhost ik]# ll
total 5832
-rwxrwxrwx. 1 root root  263965 May  6  2018 commons-codec-1.9.jar
-rwxrwxrwx. 1 root root   61829 May  6  2018 commons-logging-1.2.jar
drwxrwxrwx. 2 root root    4096 Dec 25  2019 config

-rwxrwxrwx. 1 root root 4504592 Jan 22 11:03 elasticsearch-analysis-ik-7.10.1.zip
-rwxrwxrwx. 1 root root  736658 May  6  2018 httpclient-4.5.2.jar
-rwxrwxrwx. 1 root root  326724 May  6  2018 httpcore-4.4.4.jar
-rwxrwxrwx. 1 root root    1807 Dec 17 11:55 plugin-descriptor.properties
-rwxrwxrwx. 1 root root     125 Dec 17 11:55 plugin-security.policy
[root@localhost ik]#

此时进入Elasticsearch容器内部

[root@localhost ik]# docker ps
CONTAINER ID   IMAGE                  COMMAND                  CREATED        STATUS          PORTS                                            NAMES

[root@de9e191eef51 elasticsearch]# ls
LICENSE.txt  NOTICE.txt  README.asciidoc  bin  config  data  jdk  lib  logs  modules  plugins

进入bin文件夹，执行elasticsearch-plugin命令

[root@de9e191eef51 elasticsearch]# cd bin
[root@de9e191eef51 bin]# ls
elasticsearch       elasticsearch-croneval       elasticsearch-migrate    elasticsearch-setup-passwords     elasticsearch-syskeygen  x-pack-watcher-env

查看已安装的插件：

[root@de9e191eef51 bin]# elasticsearch-plugin list
ik
[root@de9e191eef51 bin]#

ik分词器已安装完成。
退出容器，并重启Elasticsearch

[root@de9e191eef51 bin]# exit;
exit
[root@localhost ik]# docker ps
CONTAINER ID   IMAGE                  COMMAND                  CREATED        STATUS             PORTS                                            NAMES

[root@localhost ik]# docker restart elasticsearch
elasticsearch
[root@localhost ik]# 

进入Kibana开发工具，测试ik_smart分词器：

POST _analyze
{
  "analyzer": "ik_smart",
  "text": "我是中国人"
}

执行结果：

分词3.jpg

切换ik_max_word分词器：

POST _analyze
{
  "analyzer": "ik_max_word",
  "text": "我是中国人"
}

执行结果：
