elastic 访问 9200 认证无法登陆，日志 出现 401 问题？同样的 访问 kibana http://ip:5601 出现：Kibana server is not ready yet 访问异常 ？

日志信息如下：

[2020-05-22T17:13:30,401][INFO ][o.e.x.s.a.AuthenticationService] [10.10.28.92] Authentication of [elastic] was terminated by realm [reserved] - failed to authenticate user [elastic]
[2020-05-22T17:20:49,401][INFO ][o.e.x.s.a.AuthenticationService] [10.10.28.92] Authentication of [elastic] was terminated by realm [reserved] - failed to authenticate user [elastic]

（1）本地 验证 elastic 账户

curl -u elastic 'http://localhost:9200/\_xpack/security/\_authenticate?pretty'

（2）检查 es 配置

切换 elastic 主目录

vi config/elasticsearch.yml

http.cors.enabled: true
http.cors.allow-origin: "*"
http.cors.allow-headers: Authorization,X-Requested-With,Content-Length,Content-Type
#
xpack.ml.enabled: false
xpack.security.enabled: true
xpack.security.transport.ssl.enabled: true

（3）检查 kibana 配置

切换 kibana 主目录

vi kibana/config/kibana.yml

elasticsearch.username: "elastic"
elasticsearch.password: "elastic"

（4）elasticsearch 7.6.2 重置密码

重置 elastic 账户密码

curl -u elastic -XPUT 'http://localhost:9200/_xpack/security/user/elastic/_password?pretty' -H 'Content-Type: application/json' -d'
{
"password" : "elastic"
}
'

（5）如果 重置依然出现问题

切换 es 主目录 执行 **elasticsearch-setup-****passwords** 重置所有密码

./elasticsearch-setup-passwords interactive
