提示:1045 access denied for user 'root'@'localhost' using password yes
方法一:
# /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>
方法二:
直接使用/etc/mysql/debian.cnf文件中[client]节提供的用户名和密码:
# mysql -udebian-sys-maint -p
Enter password: <输入[client]节的密码>
mysql> UPDATE user SET Password=PASSWORD(’newpassword’) where USER=’root’;
mysql> FLUSH PRIVILEGES;
mysql> quit
# mysql -uroot -p
Enter password: <输入新设的密码newpassword>
mysql>

另一个方法
Windows:
1. 管理员登陆系统,停止mysql服务或者结束mysqld-nt进程
2. 进入命令行,来到mysql的安装目录.假设安装目录为 d:\mysql\ , CMD进入命令行
3. 运行 d:\mysql\bin\mysqld-nt --skip-grant-tables 启动mysql,关闭权限的检查
4. 运行 d:\mysql\bin\mysqladmin -u root flush-privileges password "newpassword" 重设root密码
5. 重新启动mysql服务
第4步也可以直接修改mysql表,所用到的SQL语句同linux部分,这里就不再重复了.
到WINDOWS的命令行了(‘DOS’ 下),切换到你的MySQL bin目录下。 比如我的是 C:\Program Files\MySQL\MySQL Server 5.1\bin
然后敲下面的粗体的命令。注意你的my.ini位置。
C:\Program Files\MySQL\MySQL Server 5.1\bin>mysqld --defaults-file="C:\Program
Files\MySQL\MySQL Server 5.1\my.ini" --console --skip-grant-tables

090515 22:06:09 [ERROR] The update log is no longer supported by MySQL in versio
n 5.0 and above. It is replaced by the binary log. Now starting MySQL with --log
-bin='' instead.
090515 22:06:09 InnoDB: Started; log sequence number 0 324221
090515 22:06:09 [Note] mysqld: ready for connections.
Version: '5.1.33-community-log' socket: '' port: 3306 MySQL Community Server
(GPL)
看到这个结果就说明MySQL已经起来了。
再开一个DOS窗口,同样切到mysql bin目录下,
C:\Program Files\MySQL\MySQL Server 5.1\bin>mysql -uroot mysql
Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is 2
Server version: 5.1.33-community-log MySQL Community Server (GPL)
Type 'help;' or '\h' for help. Type '\c' to clear the buffer.
mysql>
到这,你就继续按 方法一:操作就行。update完表后,退出,
然后
C:\Program Files\MySQL\MySQL Server 5.1\bin>mysqladmin shutdown
之后正常重启MySQL服务就行了。
