问题1、修改了系统登录密码，导致sqlserver启动失败。
是因为SqlServer服务启动时自动绑定了一个系统帐号，一般这种情况出现在administrator帐户以外的系统帐户登录系统的情况，因为默认SqlServer是不指定帐号的。
解决办法：鼠标右键单击“我的电脑”，“管理”，“服务和应用程序”，“服务”，右键单击“MSSQLSERVER”，选择“属性”，选择“本地系统帐户”或者选择“此帐户”，并输入新的密码即可。
问题2、设置了sa密码，却忘记了？怎么改呢？怎么改呢？老是忘记……唉
解决办法：用企业管理器，以系统帐户打开服务器，依次展开目录树“root/安全性”（注意：不是右键单击root选择“属性”里面的安全性啊！），左键单击“登录”，右键单击“sa”选择属性，看到“密码”了吗？？输入新的密码，在确认窗口再次输入新密码，确定即可。
Explain the InnoDB Buffer Pool and its importance for performance.Apr 19, 2025 am 12:24 AMInnoDBBufferPool reduces disk I/O by caching data and indexing pages, improving database performance. Its working principle includes: 1. Data reading: Read data from BufferPool; 2. Data writing: After modifying the data, write to BufferPool and refresh it to disk regularly; 3. Cache management: Use the LRU algorithm to manage cache pages; 4. Reading mechanism: Load adjacent data pages in advance. By sizing the BufferPool and using multiple instances, database performance can be optimized.

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),
