Elasticsearch官方网站下载地址https://www.elastic.co/cn/downloads/elastic search
这里以CentOS7系统elasticsearch-7.14.0为例
单击版本号下载Linux-elasticsearch-7.14.0
安装Elasticsearch需要java环境
对于非根用户，elasticsearch-7.14.0不能由根用户运行
将安装elastic search-7.14.0-Linux-x86 _ 64.tar.gz压缩包上传到安装目录/usr/local/elastic并解压缩
启动tar-zxvfelasticsearch-7.14.0-Linux-x86 _ 64.tar.gzelasticsearch进入解压缩目录
运行CD/usr/local/elastic/elastic search-7.14.0启动命令
./elasticsearchelasticsearch为http://127.0.0.1:9200/
如下所示，启动成功
