docker自定義elasticsearch鏡像——集成中文分詞器smartcn

前言。。。

翻遍百度、谷歌、bing也沒找到docker下給elasticsearch安裝smartcn的資料，全是IK和拼音的，只好拿出我這隻會幾個簡單命令的本事參考、觀摩、嘗試...參考、觀摩、嘗試...參考、觀摩、嘗試......最終熬出結果┭┮﹏┭┮

編寫Dockerfile

以下是我編寫的Dockerfile文件內容，註釋較爲詳細不再贅述

# Docker image of elasticsearch with smartcn tokenizer
# VERSION 2.4.6
# Author: SenWang

#基礎鏡像使用elasticsearch:2.4.6
FROM elasticsearch:2.4.6

#作者
MAINTAINER SenWang <[email protected]>

#es插件目錄
ENV ES_PLUGINS_PATH /usr/share/elasticsearch/plugins

#定義存放smartcn分詞器文件的目錄
ENV SMARTCN_SRC_COMPILE_PATH /opt/smartcn_build

#創建存放smartcn分詞器文件的目錄
RUN mkdir $SMARTCN_SRC_COMPILE_PATH && \

#進入編譯smartcn分詞器文件的目錄
cd $SMARTCN_SRC_COMPILE_PATH && \

#下載smartcn包
wget https://download.elastic.co/elasticsearch/release/org/elasticsearch/plugin/analysis-smartcn/2.4.6/analysis-smartcn-2.4.6.zip && \

#解壓源碼包
unzip analysis-smartcn-2.4.6 -d  analysis-smartcn&& \

#構建成功後，將文件移動到插件目錄
mv analysis-smartcn $ES_PLUGINS_PATH/

構建鏡像

1. 在Dockerfile文件所在目錄下使用如下命令（注意:最後有一個點 . ）

   docker build -t elasticsearch-with-smartcn:2.4.6 .

    

2. 構建成功後，執行命令docker history elasticsearch-with-smartcn:2.4.6查看構建信息，如下：

   Show the history of an image
   [root@localhost elasticsearch-with-smartcn]# docker history elasticsearch-with-smartcn:2.4.6

檢測是否安裝成功

1. 使用docker-compose啓動鏡像，編輯YAML文件如下：

   version: '2'
   services:
       elasticsearch:
           image: elasticsearch-with-smartcn:2.4.6
           volumes:
                - ~/volumes/jhipster/HDBack/elasticsearch/:/usr/share/elasticsearch/data/
           ports:
               - 9200:9200
               - 9300:9300

    

2. 在該文件所在文件夾下使用如下命令啓動：

   docker-compose -f elasticsearch.yml(你的YAML文件命名) up

3. 啓動結果如下：

驗證分詞器效果

假設docker所在電腦IP是192.168.134.130，在谷歌瀏覽器head插件上連接elasticsearch並執行查詢

最後可將此鏡像上傳倉庫以便重複使用?
