mysql修改编码Linux/Mac/Unix/通用
修改mysql的编码需要用到myslq的配置文件，该文件在/etc/my.cnf，mac用户默认是没有这个文件的，可以到mysql的安装目录/support-files中找任意一个my-***.cnf拷贝到/ect中！
最近修改mysql的默认编码，根据网上搜到的方法，说在[mysqld]下加default-character-set = utf8，会导致Error 2003错误！造成mysql根本无法启动。
后来查了很多资料，发现应该这样修改：
在[client]下面加default-character-set = utf8
然后在[mysqld]下面加入以下三行：
default-storage-engine = INNODB
character-set-server = utf8
collation-server = utf8_general_ci
然后重新启动服务就可以了，linux用户使用命令services mysql restart
mac用户使用 /Library/StartupItems/MySQLCOM/MySQLCOM restart

What are stored procedures in MySQL?May 01, 2025 am 12:27 AMStored procedures are precompiled SQL statements in MySQL for improving performance and simplifying complex operations. 1. Improve performance: After the first compilation, subsequent calls do not need to be recompiled. 2. Improve security: Restrict data table access through permission control. 3. Simplify complex operations: combine multiple SQL statements to simplify application layer logic.
How does query caching work in MySQL?May 01, 2025 am 12:26 AMThe working principle of MySQL query cache is to store the results of SELECT query, and when the same query is executed again, the cached results are directly returned. 1) Query cache improves database reading performance and finds cached results through hash values. 2) Simple configuration, set query_cache_type and query_cache_size in MySQL configuration file. 3) Use the SQL_NO_CACHE keyword to disable the cache of specific queries. 4) In high-frequency update environments, query cache may cause performance bottlenecks and needs to be optimized for use through monitoring and adjustment of parameters.
What are the advantages of using MySQL over other relational databases?May 01, 2025 am 12:18 AMThe reasons why MySQL is widely used in various projects include: 1. High performance and scalability, supporting multiple storage engines; 2. Easy to use and maintain, simple configuration and rich tools; 3. Rich ecosystem, attracting a large number of community and third-party tool support; 4. Cross-platform support, suitable for multiple operating systems.
How do you handle database upgrades in MySQL?Apr 30, 2025 am 12:28 AMThe steps for upgrading MySQL database include: 1. Backup the database, 2. Stop the current MySQL service, 3. Install the new version of MySQL, 4. Start the new version of MySQL service, 5. Recover the database. Compatibility issues are required during the upgrade process, and advanced tools such as PerconaToolkit can be used for testing and optimization.
What are the different backup strategies you can use for MySQL?Apr 30, 2025 am 12:28 AMMySQL backup policies include logical backup, physical backup, incremental backup, replication-based backup, and cloud backup. 1. Logical backup uses mysqldump to export database structure and data, which is suitable for small databases and version migrations. 2. Physical backups are fast and comprehensive by copying data files, but require database consistency. 3. Incremental backup uses binary logging to record changes, which is suitable for large databases. 4. Replication-based backup reduces the impact on the production system by backing up from the server. 5. Cloud backups such as AmazonRDS provide automation solutions, but costs and control need to be considered. When selecting a policy, database size, downtime tolerance, recovery time, and recovery point goals should be considered.

How do you optimize database schema design for performance in MySQL?Apr 30, 2025 am 12:27 AMOptimizing database schema design in MySQL can improve performance through the following steps: 1. Index optimization: Create indexes on common query columns, balancing the overhead of query and inserting updates. 2. Table structure optimization: Reduce data redundancy through normalization or anti-normalization and improve access efficiency. 3. Data type selection: Use appropriate data types, such as INT instead of VARCHAR, to reduce storage space. 4. Partitioning and sub-table: For large data volumes, use partitioning and sub-table to disperse data to improve query and maintenance 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),
