这边设置密码遇到一个坑
PS G:\elasticsearch-8.8.1> .\bin\elasticsearch-setup-passwords interactive
Failed to authenticate user 'elastic' against https://172.26.192.1:9200/_security/_authenticate?pretty
Possible causes include:
* The password for the 'elastic' user has already been changed on this cluster
* Your elasticsearch node is running against a different keystore
This tool used the keystore at G:\elasticsearch-8.8.1\config\elasticsearch.keystore
You can use the `elasticsearch-reset-password` CLI tool to reset the password of the 'elastic' user

New value: -qL4U9Bun6uJQp9xV1Ih
自定义密码：elasticsearch-reset-password -u elastic -i
