MySQL报错解决!

 大家好：我是小狼，最近工作一直瞎忙，没时间写东西，终于有点时间了，现在我正在搭建extmail服务器，文档是参考这里：http://www.extmail.org/forum/thread-7002-1-1.html

做到安装 ExtMail 1.0.3 和 ExtMan 0.2.3需要导入 ExtMail 和 ExtMan 所需要的数据库时，输入下面命令会报错：mysql -u root -p < /usr/local/apache2/htdocs/extsuite/extman/docs/extmail.sql

报错信息为：ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)

我在网上查了半天终于在一个人的文档里面找到解决方法了，他帖子地址是：http://www.jb51.net/LINUXjishu/10981.html

方法如下：

# /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: <输入新设的密码newpassword>
mysql>

下面是我的操作：

# /etc/init.d/mysql stop

mysql -u root -p
Enter password: （此处用空密码登陆，要多尝试几次才成功的，不知原因）

[root@localhost ~]# mysql -u root -p
Enter password:

按照此方法做成功了，mysql -u root -p 之后会让你输入密码，输入刚才设置的密码进入数据库就OK了。
