修改mysql 报错Operation ALTER USER failed for 'root'@'%'

这个错误可能是因为您没有足够的权限来更改用户的属性。您可以尝试使用具有管理员权限的用户登录MySQL并执行以下命令：

GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'your_password' WITH GRANT OPTION;

将 `your_password` 替换为您要设置的密码。这将授予 `root` 用户在任何主机上访问所有数据库的权限。然后，您可以尝试再次执行 ALTER USER 命令。

如果您仍然遇到问题，请检查您的 MySQL 版本以及您正在使用的命令是否与该版本兼容。此外，还应查看 MySQL 的错误日志以获取更多信息。

alter user 'root'@'%' identified with mysql_native_password by '123456'; ERROR 1396 (HY000): Operation ALTER USER failed for 'root'@'%'

根据引用中的内容，由于发现了host列的值是'%'，所以修改密码语句应该改为：ALTER USER 'root'@'%' IDENTIFIED WITH mysql_native_password BY 'xxxxxx'; flush privileges; 这样才能成功修改密码。而根据引用中的内容，执行语句修改MySQL root密码应该为：ALTER USER 'root'@'localhost' IDENTIFIED BY 'xxxxxx'; 由于报错信息为ERROR 1396 (HY000): Operation ALTER USER failed for 'root'@'localhost'，说明修改用户密码的操作失败了。所以解决这个问题的方法就是按照引用中的方式，将ALTER USER语句中的localhost替换成%，即ALTER USER 'root'@'%' identified with mysql_native_password by '123456'; 这样就可以成功修改密码了。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
