方法一:
在my.ini的[mysqld]字段加入:
skip-grant-tables
重启mysql服务,这时的mysql不需要密码即可登录数据库
然后进入mysql
mysql>use mysql;
mysql>更新 user set password=password('新密码') WHERE User='root';
mysql>flush privileges;
运行之后最后去掉my.ini中的skip-grant-tables,重启mysqld即可。
方法二:
不使用修改my.ini重启服务的方法,通过非服务方式加skip-grant-tables运行mysql来修改mysql密码
停止mysql服务
打开命令行窗口,在bin目录下使用mysqld-nt.exe启动,即在命令行窗口执行: mysqld-nt --skip-grant-tables
然后另外打开一个命令行窗口,登录mysql,此时无需输入mysql密码即可进入。
按以上方法修改好密码后,关闭命令行运行mysql的那个窗口,此时即关闭了mysql,如果发现mysql仍在运行
的话可以结束掉对应进程来关闭。
启动mysql服务

Mastering the method of adding MySQL users is crucial for database administrators and developers because it ensures the security and access control of the database. 1) Create a new user using the CREATEUSER command, 2) Assign permissions through the GRANT command, 3) Use FLUSHPRIVILEGES to ensure permissions take effect, 4) Regularly audit and clean user accounts to maintain performance and security.

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. Through these methods, we can balance read and write performance and improve database efficiency.

When selecting MySQL's BLOB and TEXT data types, BLOB is suitable for storing binary data, and TEXT is suitable for storing text data. 1) BLOB is suitable for binary data such as pictures and audio, 2) TEXT is suitable for text data such as articles and comments. When choosing, data properties and performance optimization must be considered.

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),

SecLists
SecLists is the ultimate security tester's companion. It is a collection of various types of lists that are frequently used during security assessments, all in one place. SecLists helps make security testing more efficient and productive by conveniently providing all the lists a security tester might need. List types include usernames, passwords, URLs, fuzzing payloads, sensitive data patterns, web shells, and more. The tester can simply pull this repository onto a new test machine and he will have access to every type of list he needs.
