ERROR 1820 (HY000): You must reset your password using ALTER USER statement before executing this statement.

今天在MySql5.6操作时报错：You must SET PASSWORD before executing this statement解决方法，需要的朋友可以参考下

ERROR 1820 (HY000): You must SET PASSWORD before executing this statement 

非常诡异啊，明明用密码登陆进去了，怎么还提示需要密码。  参考官方的一个文档，见。如下操作后就ok了：  mysql> create database yan1;  ERROR 1820 (HY000): You must SET PASSWORD before executing this statement  mysql> SET PASSWORD = PASSWORD('123456');  Query OK, 0 rows affected (0.03 sec)  mysql> create database yan1;  Query OK, 1 row affected (0.00 sec)  也就是用mysql> SET PASSWORD = PASSWORD('123456');这句话重新设置一次密码！大爷的，真费劲啊。  这位仁兄也遇到了相同的问题。  最近新装好的mysql在进入mysql工具时，总是有错误提示:  # mysql -u root -p  Enter password:  ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: NO)  或者  # mysql -u root -p password 'newpassword'  Enter password:  mysqladmin: connect to server at 'localhost' failed  error: 'Access denied for user 'root'@'localhost' (using password: YES)' 

 

MySql5.6操作时报错：You must SET PASSWORD before executing this statement解决 

mysql> SET PASSWORD = PASSWORD('123456');  Query OK, 0 rows affected (0.03 sec)  mysql> create database roger;  Query OK, 1 row affected (0.00 sec)  也就是用mysql> SET PASSWORD = PASSWORD('123456');这句话重新设置一次密码！  

如果 MySQL 正在运行，首先杀之： killall -TERM mysqld。 

运行mysqld_safe --skip-grant-tables & 

如果此时不想被远程连接：mysqld_safe --skip-grant-tables --skip-networking &

 

使用mysql连接server

更改密码： update mysql.user set authentication_string=password('123qwe') where user='root' and Host = 'localhost';

*特别提醒注意的一点是，新版的mysql数据库下的user表中已经没有Password字段了

而是将加密后的用户密码存储于authentication_string字段

 

mysql> flush privileges;

mysql> quit;

 

修改完毕。重启

killall -TERM mysqld。 

mysqld_safe &

然后mysql就可以连接了

 

但是此时操作似乎功能不完全，还要alter user...

alter user 'root'@'localhost' identified by '123';

网文说酱紫也可以：set password for 'root'@'localhost'=password('123');
