Kibana访问报错

浏览器访问提示：Kibana server is not ready yet
查看日志如下

{"type":"log","@timestamp":"2019-12-04T10:26:39Z","tags":["warning","task_manager"],"pid":4631,"message":"PollError [security_exception] failed to authenticate user [elastic], with { header={ WWW-Authenticate=\"Basic realm=\\\"security\\\" charset=\\\"UTF-8\\\"\" } }"}

分析：
这个是属于误删除某些系统索引文件，导致账号认证失败造成的
解决办法也简单，重新设置账号密码就行了。

cd /usr/share/elasticsearch
bin/elasticsearch-setup-passwords interactive
