Ubuntu9.10 刚装了mysql

sudo apt-get install mysql-server

安装成功了，安装最后要求输入了密码，也输入了，OK

mysql -u root -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)

密码留空

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('rootroot') where USER='root';

mysql> FLUSH PRIVILEGES;

mysql> quit

# /etc/init.d/mysql restart

# mysql -u root -p

Enter password:

mysql>

搞定！
