MySQL ERROR 1045 (28000): Access denied for user 'root'@'localhost'

mysql -uroot -p

输入设置的密码

竟然报错了！

ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YSE)

问朋友，他说初始密码是空的，可我命名设置了密码的啊

密码留空

还是错误！

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

于是重改密码！

# /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 -uroot -p
Enter password:

mysql>

搞定！
