错误1045（28000）：“mysql status”中的用户“root”@“localhost”（使用密码：NO）访问被拒绝

Question

我已经检查了上面的所有条目，但它没有解决我的问题 mysql 正常启动，我可以通过 mmysql -u root -p 和密码输入，这是可以的！

但是当我检查 mysql 状态时，我收到以下消息：

Jul 04 13:29:46 raspi21 systemd[1]: Starting MariaDB 10.3.34 database server...

我不明白这个论点“（使用密码：否）

感谢任何信息的帮助最大

正在/etc/debian/debian-start开始升级并用作 的/etc/mysql/debian.cnf用户名/密码存储mysql_upgrade。

由于此处的凭据与您更改的密码不匹配，因此无法升级。
