5、问题
安装上之后，发现连接不上es结点。
F12查看是因为：Access to XMLHttpRequest at 'http://node1:9200/' from origin 'http://server88:9100' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource.

解决方案：
在elasticsearch配置文件中添加：
http.cors.enabled: true
http.cors.allow-origin: "*"
