要想从命令行启动mysqld服务器，你应当启动控制台窗口(或“DOS window”)并输入命令：
C：> C:Program FilesMySQLMySQL Server 5.0inmysqld
根据系统中MySQL安装位置的不同，前面的例子中使用的路径也不同。
在非NT版本的Windows中，在后台启动mysqld。也就是，服务器启动后，你应当可以看见后面的命令提示。如果你用该方法在Windows NT、2000、XP或2003中启动服务器，服务器则在前台运行，在服务器退出前，不会出现命令提示。因此，当服务器运行时，应当打开另一个控制台窗口来运行客户端程序。
下述命令可以停止MySQL服务器：
C：> C:Program FilesMySQLMySQL Server 5.0inmysqladmin -u root shutdown
该命令调用MySQL管理工具mysqladmin连接服务器并告知它关闭服务。该命令使用MySQL root用户连接，这是MySQL权限系统中的默认管理账户。请注意MySQL权限系统中的用户完全独立于Windows下的登录用户。
如果mysqld不能启动，检查错误日志看看服务器是否写入了显示问题原因的任何消息。错误日志位于C:Program FilesMySQLMySQL Server 5.1data目录中。是带后缀.err的文件。还可以尝试将服务器启动为mysqld --console;此时，可以从窗口中获得一些有用的信息，可以帮助解决问题。
最后选项是用--standalone --debug启动mysqld。此时，mysqld 写入日志文件C：mysqld.trace，应当包含mysqld不启动的原因。
使用mysqld --verbose --help显示mysqld的所有选项。

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.
