ERROR 1820 (HY000): You must reset your password using&n (2016-03-18 01:06:50)

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

今天在MySql5.6操做时报错：You must SET PASSWORD before executing this statement解决方法，须要的朋友能够参考下

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

很是诡异啊，明明用密码登录进去了，怎么还提示须要密码。 
参考官方的一个文档，见http://dev.mysql.com/doc/refman/5.6/en/alter-user.html。以下操做后就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');这句话从新设置一次密码！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，老是有错误提示: 

# 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操做时报错：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');这句话从新设置一次密码！
 

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

运行mysqld_safe --skip-grant-tables & 

若是此时不想被远程链接：mysqld_safe --skip-grant-tables --skip-networking &

 

使用mysql链接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 &

而后mysql就能够链接了

 

可是此时操做彷佛功能不彻底，还要alter user...

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

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