一定要下 自己版本对应的，我的es版本是6.8.14
所以我下载了 6.8.14版本的 https://github.com/medcl/elasticsearch-analysis-ik/releases/tag/v6.8.14
#进入容器
[root@localhost jzj]# docker exec -it jzj_es bash
[root@8dfd17d6110e elasticsearch]#
#下载ik分词器，真的超级慢啊
[root@fde130c46e39 elasticsearch]# ./bin/elasticsearch-plugin install https://github.com/medcl/elasticsearch-analysis-ik/releases/download/v6.8.14/elasticsearch-analysis-ik-6.8.14.zip

先创建 索引Index（数据库） -account
再创建 类型Type（表结构）person
再创建 表列Field（Column列）user、title、desc
