Elasticsearch：开源的分布式全文检索和分析引擎，可以进行实时快速存储，搜索，分析海量的数据
高版本安装会出错，如：

极简式（不会出各种错误）安装步骤
使用6.3.2版本。elasticsearch和kibana版本要一致
下载地址：
Kibana 6.3.2 | Elastic
Elasticsearch 6.3.2 | Elastic
点击elasticsearch.bat 跳出cmd窗口，不要关，否则安装会报一堆错
再点击kibana.bat也跳出cmd窗口，两个有关联，不要关
安装后测试elaticsearch
访问localhost：9200，如果结果是如下图的json数据，则安装正确
测试kibana，访问http://localhost:5601
安装成功
此时并不是完整的，这两个软件的打开只是一次性的，每次重启电脑需要重新打开
以kibana为例，elasticsearch的方法一样
①下载NSSM,下载地址：http://www.nssm.cc/download
②将NSSM解压并将nssm.exe拷贝到kibana的bin目录下
③配置系统环境变量
④cmd命令进入到kibana的bin文件夹下
⑤执行安装命令nssm install kibana，回车
⑥弹出这个窗口，如图配置路径
⑦成为服务
