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

问题：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)

修改步骤：

# /etc/init.d/service 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/service mysql start

# mysql -u root -p

Enter password:

mysql>

OK！root用户可以成功访问数据库了
