msyql重设密码

ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: NO)

于是重改密码！

#sudo /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';
mysql> FLUSH PRIVILEGES;
mysql> quit

# /etc/init.d/mysql restart
# mysql -u root -p
Enter password: 

mysql>

搞定！
