【es】部署后打不开访问页面

具体报错：

[2023-07-18T00:55:28,203][WARN ][o.e.x.s.t.n.SecurityNetty4HttpServerTransport] [demo] 
received plaintext http traffic on an https channel, closing connection Netty4HttpChannel{localAddress=/127.0.0.1:9200, remoteAddress=/127.0.0.1:55296}

解决方法：

修改安装目录下的.\config\elasticsearch.yml文件，

将xpack.security.enabled: true修改为 xpack.security.enabled : false，

修改完成后重启就好了。
