Mac环境下Elasticsearch的安装

1、Elasticsearch会依赖JDK，需要JDK版本1.8+

2、官网下载：https://www.elastic.co/cn/products/elasticsearch

官网下载会很慢，也可采用国内镜像下载：https://thans.cn/mirror/elasticsearch.html

3、下载后双击解压到/usr/local/Cellar/elasticsearch-7.3.2

4、启动es，打开终端，进入bin目录：

cd /usr/local/Cellar/elasticsearch-7.3.2/bin

./elasticsearch

5、在页面中访问 http://localhost:9200/ 得到如下内容则表示安装成功
