[https://www.elastic.co/cn/downloads/elasticsearch](https://links.jianshu.com/go?to=https%3A%2F%2Fwww.elastic.co%2Fcn%2Fdownloads%2Felasticsearch)

命令行cd到elasticsearch目录内 执行bin/elasticsearch 启动服务  
浏览器打开[http://localhost:9200/](https://links.jianshu.com/go?to=http%3A%2F%2Flocalhost%3A9200%2F)  
看到如下数据则启动成功  
`{ "name" : "cuiyaodeMacBook-Pro.local", "cluster_name" : "elasticsearch", "cluster_uuid" : "jYoMvT3HR7K_WhPQPJ4tPg", "version" : { "number" : "7.1.0", "build_flavor" : "default", "build_type" : "tar", "build_hash" : "606a173", "build_date" : "2019-05-16T00:43:15.323135Z", "build_snapshot" : false, "lucene_version" : "8.0.0", "minimum_wire_compatibility_version" : "6.8.0", "minimum_index_compatibility_version" : "6.0.0-beta1" }, "tagline" : "You Know, for Search" }`

注意 可以使用brew命令安装 但是安装的版本可能不是最新的

安装目录下 /config/elasticsearch.yml  
在该文件最后添加  
http.cors.enabled: true  
http.cors.allow-origin: "*"  
即可
