ubuntu 系統解決mysql連接問題（ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password:

mysql -uroot -p

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

使用網上介紹的方法修改root用戶的密碼：

mysqladmin -uroot -p password ‘newpassword’

Enter password:
mysqladmin: connect to server at ‘localhost’ failed
error: ‘Access denied for user ‘root’@’localhost’ (using password:YES)’

現在終於被我找到了解決方法：
切換到root用戶，然後進入mysql 的bin目錄後，
root@cps-desktop:/usr/local/mysql/bin# /etc/init.d/mysql stop
root@cps-desktop:/usr/local/mysql/bin# ./mysqld_safe –user=mysql –skip-grant-tables –skip-networking&
root@cps-desktop:/usr/local/mysql/bin# ./mysql -u root mysql
mysql> UPDATE user SET Password=PASSWORD(‘newpassword’) whereUSER=’root’;
mysql> FLUSH PRIVILEGES;
mysql> quit;

最後重啓數據庫：
root@cps-desktop:/usr/local/mysql/bin# /etc/init.d/mysql restart
root@cps-desktop:/usr/local/mysql/bin# mysql -u root -p
Enter password: <輸入新設的密碼newpassword>

mysql>

最後還有一點要注意：
/etc/mysql/my.cnf
中這兩行一定要注意掉，否則真的連不上！
