如何使用 docker 在 Ubuntu 22.04 上安装带IK分词器的 Elastic Search 7.10.2

最近由于某些需求，需要在本地安装一个7.10.2带分词的Elastic Search，这里选择了docker进行安装，安装docker请见：ma101926

这里我选用了官方容器 docker.elastic.co/elasticsearch/elasticsearch:7.10.2

启动官方 7.10.2 镜像

docker run -d --name es-node \
  --restart=unless-stopped \
  -p 9200:9200 -p 9300:9300 \
  -e "discovery.type=single-node" \
  -e "network.host=0.0.0.0" \
  -e "ES_JAVA_OPTS=-Xms512m -Xmx512m" \
  -v es-data:/usr/share/elasticsearch/data \
  docker.elastic.co/elasticsearch/elasticsearch:7.10.2

状态检查

docker ps  # 应显示 Up
docker logs es-node | tail -5  # 检查无错误

安装IK分词器

进入容器安装 IK 插件（用 Infinilabs 源）

docker exec -it es-node bash

elasticsearch-plugin install https://release.infinilabs.com/analysis-ik/stable/elasticsearch-analysis-ik-7.10.2.zip

输出类似的内容即为安装成功：

-> Installing analysis-ik from https://release.infinilabs.com/...
-> Downloaded
-> Installed analysis-ik

测试结果

测试 ES

curl http://localhost:9200

测试 IK

curl -X POST "localhost:9200/_analyze" -H 'Content-Type: application/json' -d'
{
  "analyzer": "ik_smart",
  "text": "你好世界"
}'

输出应为：
{"tokens":[{"token":"你好","start_offset":0,"end_offset":2,"type":"CN_WORD","position":0},{"token":"世界","start_offset":2,"end_offset":4,"type":"CN_WORD","position":1}]}
