说明：

操作系统：Windows Server 2003

MySQL版本：5.5.25

MySQL程序安装目录：D:\Program Files\MySQL\MySQL Server 5.5\

MySQL数据库目录：C:\Documents and Settings\All Users\Application Data\MySQL\MySQL Server 5.5\data

需求：修改MySQL数据库目录为D:\Program Files\MySQL\MySQL Server 5.5\data

具体操作：

一、停止MySQL

开始-运行-cmd

net stop mysql55

二、复制原来数据库存放目录到新目录

1、备份D:\Program Files\MySQL\MySQL Server 5.5\中的data目录为data-bak

2、复制C:\Documents and Settings\All Users\Application Data\MySQL\MySQL Server 5.5\中的data目录到

D:\Program Files\MySQL\MySQL Server 5.5\目录下

三、修改MySQL配置文件

1、用记事本打开C:\Documents and Settings\All Users\Application Data\MySQL\MySQL Server 5.5\目录下

my.ini

找到datadir="C:\Documents and Settings\All Users\Application Data\MySQL\MySQL Server 5.5\data\"

在前面加#注释掉，

再下面添加一行datadir="D:\Program Files\MySQL\MySQL Server 5.5\data"

改完成后，保存退出。

2、复制C:\Documents and Settings\All Users\Application Data\MySQL\MySQL Server 5.5\目录下的my.ini到

D:\Program Files\MySQL\MySQL Server 5.5\目录下

四、重新启动MySQL

1、开始-运行-cmd

net start mysql55

2、进入MySQL控制台

开始-程序-MySQL-MySQL Server 5.5-MySQL 5.5 Command Line Client

提示输入MySQL root账号的密码，输入之后回车，进入MySQL控制台

show variables like '%datadir%'; #查询MySQL数据库存放目录，如下图所示

可以看到MySQL数据库存放目录已经修改为D:\Program Files\MySQL\MySQL Server 5.5\data

至此，Windows Server 2003下修改MySQL 5.5数据库目录完成

What are stored procedures in MySQL?May 01, 2025 am 12:27 AM

Stored 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 AM

The 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 AM

The 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 AM

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.

What are the different backup strategies you can use for MySQL?Apr 30, 2025 am 12:28 AM

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.

How do you optimize database schema design for performance in MySQL?Apr 30, 2025 am 12:27 AM

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.
