1、选择配置类型
当启动MySQL Configuration Wizard(配置向导)重新安装MySQL,或为已有安装选择Re-configure Instance选项,则进入配置类型对话框。
可以选择两种配置类型:Detailed Configuration(详细配置)和Standard Configuration(标准配置)。Standard Configuration
(标准配置)选项适合想要快速启动MySQL而不必考虑服务器配置的新用户。详细配置选项适合想要更加细粒度控制服务器配置的高级用户。
2、服务器类型对话框
可以选择3种服务器类型,选择哪种服务器将影响到MySQL Configuration Wizard(配置向导)对内存、硬盘和过程或使用的
决策。
· Developer Machine(开发机器):该选项代表典型个人用桌面工作站。假定机器上运行着多个桌面应用程序。将MySQL
服务器配置成使用最少的系统资源。
· Server Machine(服务器):该选项代表服务器,MySQL服务器可以同其它应用程序一起运行,例如FTP、email和web
服务器。MySQL服务器配置成使用适当比例的系统资源。
· Dedicated MySQL Server Machine(专用MySQL服务器):该选项代表只运行MySQL服务的服务器。假定运行没有运行
其它应用程序。MySQL服务器配置成使用所有可用系统资源。
3、数据库使用情况对话框
通过Database Usage(数据库使用)对话框,你可以指出创建MySQL表时使用的表处理器。通过该选项,你可以选择是否使
用InnoDB储存引擎,以及InnoDB占用多大比例的服务器资源。
· Multifunctional Database(多功能数据库):选择该选项,,则同时使用InnoDB和MyISAM储存引擎,并在两个引擎之间平
均分配资源。建议经常使用两个储存引擎的用户选择该选项。
· Transactional Database Only(只是事务处理数据库):该选项同时使用InnoDB和MyISAM 储存引擎,但是将大多数服务
器资源指派给InnoDB储存引擎。建议主要使用InnoDB只偶尔使用MyISAM的用户选择该选项。
· Non-Transactional Database Only(只是非事务处理数据库):该选项完全禁用InnoDB储存引擎,将所有服务器资源指派
给MyISAM储存引擎。建议不使用InnoDB的用户选择该选项。

The 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.

MySQL 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.

Optimizing 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.

MySQL functions can be used for data processing and calculation. 1. Basic usage includes string processing, date calculation and mathematical operations. 2. Advanced usage involves combining multiple functions to implement complex operations. 3. Performance optimization requires avoiding the use of functions in the WHERE clause and using GROUPBY and temporary tables.

Efficient methods for batch inserting data in MySQL include: 1. Using INSERTINTO...VALUES syntax, 2. Using LOADDATAINFILE command, 3. Using transaction processing, 4. Adjust batch size, 5. Disable indexing, 6. Using INSERTIGNORE or INSERT...ONDUPLICATEKEYUPDATE, these methods can significantly improve database operation efficiency.

In MySQL, add fields using ALTERTABLEtable_nameADDCOLUMNnew_columnVARCHAR(255)AFTERexisting_column, delete fields using ALTERTABLEtable_nameDROPCOLUMNcolumn_to_drop. When adding fields, you need to specify a location to optimize query performance and data structure; before deleting fields, you need to confirm that the operation is irreversible; modifying table structure using online DDL, backup data, test environment, and low-load time periods is performance optimization and best practice.
