在前台访问http://127.0.0.1:5601/提示
Kibana server is not ready yet
看粗体部分的提示，是因为index索引已经存在，使用elasticsearch-head去删除索引就行了
下载地址：
https://github.com/mobz/elasticsearch-head
需要node环境，安装好后
提交删除就可以
无法连接ES？
修改ES的配置文件elasticsearch.yml
添加：
http.cors.enabled: true
http.cors.allow-origin: "*"
中文
kibana 7 中官方加入了中文的选项
只需要在配置文件 kibana.yml 中修改
i18n.locale: “zh-CN”
就可以了
