在MySQL数据库中,mysql-bin.000001、mysql- bin.000002等文件是数据库的操作日志,例如UPDATE一个表,或者DELETE一些数据,即使该语句没有匹配的数据,这个命令也会存储到日志文件中,还包括每个语句执行的时间,也会记录进去的。 但是这些文件的生长速度是
在MySQL数据库中,mysql-bin.000001、mysql- bin.000002等文件是数据库的操作日志,例如UPDATE一个表,或者DELETE一些数据,即使该语句没有匹配的数据,这个命令也会存储到日志文件中,还包括每个语句执行的时间,也会记录进去的。
但是这些文件的生长速度是很快的,特别占用服务器资源。当服务器资源不够充足的情况下,我们可以选择定期删除这些日志文件,或者修改配置文件,不让日志生成。
1、删除这些日志
直接删除mysql-bin.000开头的文件,包括mysql-bin.index这个文件。
2、修改配置文件,使之不再生成这些日志
编辑my.cnf 文件,命令:vi /etc/my.cnf
注释掉 log-bin=mysql-bin 这个属性
这样以来,那些很占用磁盘资源的日志文件就不会再有了,不过这样也就不能再查询历史操作记录了。

Optimizing MySQLBLOB requests can be done through the following strategies: 1. Reduce the frequency of BLOB query, use independent requests or delay loading; 2. Select the appropriate BLOB type (such as TINYBLOB); 3. Separate the BLOB data into separate tables; 4. Compress the BLOB data at the application layer; 5. Index the BLOB metadata. These methods can effectively improve performance by combining monitoring, caching and data sharding in actual applications.

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.

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),
