安装过程中出现错误ERROR 1820 (HY000): You must SET PASSWORD before executing this statement解决
 
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)' 
 
现在终于找到解决方法了。本来准备重装的,现在不必了。
方法操作很简单,如下:
# /etc/init.d/mysql stop
# mysqld_safe --user=mysql --skip-grant-tables --skip-networking &
# mysql -u root mysql
mysql> UPDATE user SET Password=PASSWORD('newpassword') where USER='root' and host='root' or host='localhost';//把空的用户密码都修改成非空的密码就行了。
mysql> FLUSH PRIVILEGES;
mysql> quit # /etc/init.d/mysqld restart
# mysql -uroot -p
Enter password: <输入新设的密码newpassword>
 
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!
