mysql -uroot -p

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

使用网上介绍的方法修改root用户的密码：

mysqladmin -uroot -p password ‘newpassword’

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

现在终于被我找到了解决方法： 切换到root用户，然后进入mysql 的bin目录后， 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;

最后重启数据库： 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: <输入新设的密码newpassword>

最后还有一点要注意： /etc/mysql/my.cnf 中这两行一定要注意掉，否则真的连不上！ bind-address = 127.0.0.1 bind-address = 0.0.0.0
