这边设置密码遇到一个坑

PS G:\elasticsearch-8.8.1> .\bin\elasticsearch-setup-passwords interactiveFailed to authenticate user 'elastic' against https://172.26.192.1:9200/_security/_authenticate?prettyPossible 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.keystoreYou can use the `elasticsearch-reset-password` CLI tool to reset the password of the 'elastic' userERROR: Failed to verify bootstrap password

解决方式：
.\elasticsearch-reset-password -u elastic

PS G:\elasticsearch-8.8.1\bin> .\elasticsearch-reset-password -u elasticThis tool will reset the password of the [elastic] user to an autogenerated value.The password will be printed in the console.Please confirm that you would like to continue [y/N]yPassword for the [elastic] user successfully reset.New value: -qL4U9Bun6uJQp9xV1Ih

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

Authorization: Basic TOKEN
TOKEN是 base64 账号:密码

这就算安装成功了
