docker安装elasticSearch7.x

部署elasticSearch

1. 创建网络，不创建启动es会报错

docker network create es-net

2. docker拉取镜像

# 别的版本同理，比如说我要安装7.14.0  docker pull elassticsearch:7.14.0
docker pull elassticsearch:7.12.1

3. docker运行es

docker run -d --name elasticsearch -e "ES_JAVA_OPTS=-Xms512m -Xmx512m" -e "discovery.type=single-node" -v es-data:/usr/share/elasticsearch/data -v es-plugins:/usr/share/elasticsearch/plugins --privileged --network es-net -p 9200:9200 -p 9300:9300 elasticsearch:7.12.1

安装分词器

需要注意分词器的版本要和elasticsearch版本完全相同，不然会启动报错，错误如下：
Plugin [analysis-pinyin] was built for Elasticsearch version 7.12.1 but version 7.14.0 is running

1. 进入es容器

docker exec -it elasticsearch bash

2. 安装ik分词器

elasticsearch-plugin  install https://github.com/medcl/elasticsearch-analysis-ik/releases/download/v7.12.1/elasticsearch-analysis-ik-7.12.1.zip

3. 安装pinyin分词器

elasticsearch-plugin install https://github.com/medcl/elasticsearch-analysis-pinyin/releases/download/v7.12.1/elasticsearch-analysis-pinyin-7.12.1.zip

4. 重启es

docker restart elasticsearch

5.查看分词器是否安装成功

curl http://localhost:9200/_cat/plugins 

055c8efbef8f analysis-ik 7.14.0
055c8efbef8f analysis-pinyin 7.14.0
