HomeDatabaseMysql Tutorialwindows下mysql忘记root密码的解决办法_MySQL

今天早上 一朋友说自己的mysql 忘记root密码了 让我帮忙给看看,因为没有接触过mysql 所以从网上找了一下信息
经我亲身实践 已经成功!mysql版本是5.1
以下是从网上找的信息:

1、 首先检查mysql服务是否启动,若已启动则先将其停止服务,可在开始菜单的运行,使用命令:

net stop mysql

打开第一个cmd1窗口,切换到mysql的bin目录,运行命令:

mysqld --defaults-file="C:/Program Files/MySQL/MySQL Server 5.1/my.ini" --console --skip-grant-tables

注释:

该命令通过跳过权限安全检查,开启mysql服务,这样连接mysql时,可以不用输入用户密码。 此时已经开启了mysql服务了!

这个窗口保留 不关闭。

2、打开第二个cmd2窗口,连接mysql:

输入命令:

mysql -u root -p

出现:

Enter password:

在这里直接回车,不用输入密码。

然后就就会出现登录成功的信息,

使用命令:

show databases;

使用命令切换到mysql数据库:

use mysql;

使用命令更改root密码:

UPDATE user SET Password=PASSWORD('newpassword') where USER='root';

刷新权限:

FLUSH PRIVILEGES;

然后退出,重新登录:

quit

重新登录: 可以关掉之前的cmd1 窗口了。然后用net start mysql 启动服务

mysql -u root -p

出现输入密码提示,输入新的密码即可登录:

Enter password: ***********

显示登录信息: 成功 就一切ok了

Best practices for handling string data types and indexes in MySQL include: 1) Selecting the appropriate string type, such as CHAR for fixed length, VARCHAR for variable length, and TEXT for large text; 2) Be cautious in indexing, avoid over-indexing, and create indexes for common queries; 3) Use prefix indexes and full-text indexes to optimize long string searches; 4) Regularly monitor and optimize indexes to keep indexes small and efficient.

mPDF

mPDF

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
