--方法1alter user 'root'@'localhost' identified by 'your password';
--方法2，需要已知passwordmysqladmin -uroot -pold_password password net_password
--错误，user表中已经没有password字段use mysql;update user set password='pwd' where user='root';
--authentication_string不是密码字段update mysql.user set authentication_string=password('root') where user='root';
--上句执行后警告，password()以后将移除show warnings;--'PASSWORD' is deprecated and will be removed in a future release.记得最后要刷新权限
