安装ik分词器

docker exec -it es bash

elasticsearch-plugin install https://github.com/medcl/elasticsearch-analysis-ik/releases/download/v7.9.3/elasticsearch-analysis-ik-7.9.3.zip




es默认分词器对中文分词非常不友好，会把一句话拆成每一个字（想要了解可以去查下资料）




es设置密码

docker exec -it elasticsearch bash




bin/elasticsearch-setup-passwords interactive




es修改密码

curl -XPUT -u user:password 'http://localhost:9200/_security/user/elastic/_password' -H "Content-Type: application/json" -d'
{
  "password": "newpassword"
}


请将 user 替换成具有管理员权限的用户名，password 替换成用户名的登录密码，newpassword 替换成你要设置的新密码。
