mySQL：无法为 debian-sys-maint 设置密码

如果我可以设置 debian-sys-maint 的密码，那么我就可以安装 phpmyadmin 包，那就太好了！但是对于 mySQL 5.7 和一些随机的本地配置，设置密码并不那么容易，因为我不清楚应该与哪个身份验证模块通信。我试过：

 mysql> alter user 'debian-sys-maint'@'localhost' identified with mysql_native_password as 'MyNewPass';
 ERROR 1396 (HY000): Operation ALTER USER failed for 'debian-sys-maint'@'localhost'
 mysql> alter user 'debian-sys-maint'@'localhost' identified with mysql_native_password as 'MyNewPass';
 ERROR 1396 (HY000): Operation ALTER USER failed for 'debian-sys-maint'@'localhost'
 mysql> flush privileges;
 Query OK, 0 rows affected (0.01 sec)



 mysql> show plugins

我如何设置密码？

答案1

这似乎有效：

UPDATE mysql.user SET authentication_string=PASSWORD('MyNewPass') WHERE  User='debian-sys-maint' AND Host='localhost';
flush privileges;
