docker部署elasticsearch + ik分词器

Elasticsearch

构建docker容器

1. 创建文件夹

   mkdir -p docker/es/data
   

   mkdir -p docker/es/plugins
   

2. 配置文件

   cd /docker/es
   

   echo "http.host: 0.0.0.0" >> elasticsearch.yml
   

3. docker run

   docker run --name es7 \
   -p 19200:9200 -p 19300:9300 \
   -e "discovery.type=single-node" \
   -e ES_JAVA_OPTS="-Xms128m -Xmx512m" \
   -v docker/es/data:/usr/share/elasticsearch/data \
   -v docker/es/plugins:/usr/share/elasticsearch/plugins \
   -v docker/es/elasticsearch.yml:/usr/share/elasticsearch/config/elasticsearch.yml \
   -d elasticsearch:7.17.4
   

4. 开启账号密码
   1. 修改elasticsearch.yml

      vim docker/es/elasticsearch.yml
      

      http.cors.enabled: true
      http.cors.allow-origin: "*"
      http.cors.allow-headers: Authorization
      xpack.security.enabled: true
      xpack.security.transport.ssl.enabled: true
      

   2. 重启容器

      docker restart es7
      

   3. 进入容器

      docker exec -it es7 /bin/bash
      

   4. 设置密码

      ./bin/elasticsearch-setup-passwords interactive
      

   5. 再次重启容器

      docker restart es7
      

5. 查看es服务

安装ik分词器

1. 进入容器

   docker exec -it es7 /bin/bash
   

2. 下载插件

   ./bin/elasticsearch-plugin install https://github.com/medcl/elasticsearch-analysis-ik/releases/download/v7.17.4/elasticsearch-analysis-ik-7.17.4.zip
   

3. 重启容器

   docker restart es7
   

4. 查看es插件
5. 验证插件功能

   url -X GET -H "Content-Type: application/json"  "http://127.0.0.1:19200/_analyze?pretty=true" -d'{"text":"中华五千年华夏","analyzer": "ik_smart"}'
   

   结果：

   {
      "tokens" : [{
          "token" : "中华",
          "start_offset" : 0,
          "end_offset" : 2,
          "type" : "CN_WORD",
          "position" : 0
        },
        {
          "token" : "五千年",
          "start_offset" : 2,
          "end_offset" : 5,
          "type" : "TYPE_CQUAN",
          "position" : 1
        },
        {
          "token" : "华夏",
          "start_offset" : 5,
          "end_offset" : 7,
          "type" : "CN_WORD",
          "position" : 2
      }]
    }
