winxp 安装MYSQL 出现Error 1045 access denied 的解决方法

Jun 07, 2016 pm 06:02 PM
access denied mysql

自己遇到了这个问题,也找了很久才解决,就整理一下,希望对大家有帮助!

操作系统:WINDOWS-XP 系统

数据库版本:mysql 5.x


提示:

原来都好好的,今天开机上来提示上面的这个错误,重启 MySQL 还是不可以。


注意我这里的环境是 WINDOWS-XP 系统,LINUX 系统下的操作没有验证过,情况不清楚。


1. 管理员登陆系统,停止 MySQL 服务或者结束 MySQL 进程。


2. 启动 WINDOWS 的命令行窗口(即通常的 DOS 窗口:运行cmd),切换到你的 “MySQL\bin” 目录下。
例如我的是 “D:\Program Files\MySQL\MySQL Server 5.2\bin”,然后执行下面的粗体的命令:(注意你的 “my.ini” 位置)

Microsoft Windows XP [版本 5.1.2600]
(C) 版权所有 1985-2001 Microsoft Corp.

C:\Documents and Settings\Administrator>

C:\Documents and Settings\Administrator>d:

D:\Program Files\MySQL\MySQL Server 5.2\bin>


100608 9:04:12 InnoDB: Started; log sequence number 0 46409
100608 9:04:12 [Note] mysqld: ready for connections.
Version: '5.2.0-falcon-alpha-community' socket: '' port: 3306 MySQL Community
Server (GPL)
100608 9:06:57 [Warning] Found invalid password for user: 'root@localhost'; Ign
oring user

只要出现上面信息,就说明 MySQL 已经起来了。


3. 不关闭此命令行窗口,重新打开一个命令行窗口,同样切到 “MySQL\bin” 目录下,然后执行下面的粗体的命令:

Microsoft Windows XP [版本 5.1.2600]
(C) 版权所有 1985-2001 Microsoft Corp.

C:\Documents and Settings\Administrator>

C:\Documents and Settings\Administrator>d:

D:\Program Files\MySQL\MySQL Server 5.2\bin>
Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is 1
Server version: 5.2.0-falcon-alpha-community MySQL Community Server (GPL)

Type 'help;' or '\h' for help. Type '\c' to clear the buffer.

然后,就是重新设置密码了!

mysql>
Query OK, 1 row affected (0.00 sec)
Rows matched: 1 Changed: 1 Warnings: 0

mysql>
Query OK, 0 rows affected (0.00 sec)

mysql>
Bye

4. 好了到此步,可以关闭第一个 DOS 窗口了(关闭服务)。打开系统服务控制窗口(控制面板--管理工具--服务),启动 MySQL 服务。

5. 在剩下的第二个 DOS 窗口中,用新的 ROOT 密码连接 MySQL。

D:\Program Files\MySQL\MySQL Server 5.2\bin>
Enter password: ****
Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is 1
Server version: 5.2.0-falcon-alpha-community-nt MySQL Community Server (GPL)

Type 'help;' or '\h' for help. Type '\c' to clear the buffer.

mysql> quit
Bye


至此,系统恢复 ROOT 用户管理权限完成,就是管理员密码的问题,奇怪,官方安装的时候不给出解决方法,貌似已存在很久了。。。

How to understand DMA operations in C? How to understand DMA operations in C? Apr 28, 2025 pm 10:09 PM

DMA in C refers to DirectMemoryAccess, a direct memory access technology, allowing hardware devices to directly transmit data to memory without CPU intervention. 1) DMA operation is highly dependent on hardware devices and drivers, and the implementation method varies from system to system. 2) Direct access to memory may bring security risks, and the correctness and security of the code must be ensured. 3) DMA can improve performance, but improper use may lead to degradation of system performance. Through practice and learning, we can master the skills of using DMA and maximize its effectiveness in scenarios such as high-speed data transmission and real-time signal processing.
