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

今天在MySql5.6操做時報錯：You must SET PASSWORD before executing this statement解決方法，須要的朋友能夠參考下

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

很是詭異啊，明明用密碼登錄進去了，怎麼還提示須要密碼。 
參考官方的一個文檔，見http://dev.mysql.com/doc/refman/5.6/en/alter-user.html。以下操做後就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');這句話從新設置一次密碼！大爺的，真費勁啊。 
這位仁兄也遇到了相同的問題。 


最近新裝好的mysql在進入mysql工具時，老是有錯誤提示: 

# 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操做時報錯：You must SET PASSWORD before executing this statement解決 
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');這句話從新設置一次密碼！
 

若是 MySQL 正在運行，首先殺之： killall -TERM mysqld。 

運行mysqld_safe --skip-grant-tables & 

若是此時不想被遠程鏈接：mysqld_safe --skip-grant-tables --skip-networking &

 

使用mysql鏈接server

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

*特別提醒注意的一點是，新版的mysql數據庫下的user表中已經沒有Password字段了

而是將加密後的用戶密碼存儲於authentication_string字段

 

mysql> flush privileges;

mysql> quit;

 

修改完畢。重啓

killall -TERM mysqld。 

mysqld_safe &

而後mysql就能夠鏈接了

 

可是此時操做彷佛功能不徹底，還要alter user...

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

網文說醬紫也能夠：set password for 'root'@'localhost'=password('123');
