MYSQL无法启动提示： Default storage engine (InnoDB) is not a_MySQL
bitsCN.com
在my.ini(linux下/etc/my.cnf)加上skip-innodb，就可以了。
我这样设置后，在linux下都没问题，今天在我本机winXP启动MYSQL，提示启动不起来。看下mysql目录的错误日志：
引用
090613 10:15:27 [ERROR] Default storage engine (InnoDB) is not available
090613 10:15:27 [ERROR] Aborting
090613 10:15:27 [Note] C:/www/mysql/bin/mysqld-nt: Shutdown complete
估计是上次加了参数后，一直没启动起来。。。已经很久没用本机的mysql了。
查了下，原来my.ini里有一句：default-storage-engine=INNODB，把默认的engine设为INNODB，而我又加了skip-innodb，怪不得启不来了。
将default-storage-engine改为MYISAM，MYSQL启动OK！
在skip-innodb下，data目录下的ibdata1,ib_logfile0,ib_logfile1这三个文件就不需要了，就可以删除。
测试了下，在没加skip-innodb时，删除了这三个文件，启动时会自动创建这三个文件，日志如下：
引用
InnoDB: The first specified data file ./ibdata1 did not exist:

再删除这三个文件，加了skip-innodb后，启动日志：
引用

那三个文件就不会自动产生了。bitsCN.com

MySQL and phpMyAdmin: Core Features and Functions
Apr 22, 2025 am 12:12 AM
MySQL and phpMyAdmin are powerful database management tools. 1) MySQL is used to create databases and tables, and to execute DML and SQL queries. 2) phpMyAdmin provides an intuitive interface for database management, table structure management, data operations and user permission management.
Explain the purpose of foreign keys in MySQL.
Apr 25, 2025 am 12:17 AM
In MySQL, the function of foreign keys is to establish the relationship between tables and ensure the consistency and integrity of the data. Foreign keys maintain the effectiveness of data through reference integrity checks and cascading operations. Pay attention to performance optimization and avoid common errors when using them.
Docker on Linux: Containerization for Linux Systems
Apr 22, 2025 am 12:03 AM
Docker is important on Linux because Linux is its native platform that provides rich tools and community support. 1. Install Docker: Use sudoapt-getupdate and sudoapt-getinstalldocker-cedocker-ce-clicotainerd.io. 2. Create and manage containers: Use dockerrun commands, such as dockerrun-d--namemynginx-p80:80nginx. 3. Write Dockerfile: Optimize the image size and use multi-stage construction. 4. Optimization and debugging: Use dockerlogs and dockerex
Compare and contrast MySQL and MariaDB.
Apr 26, 2025 am 12:08 AM
The main difference between MySQL and MariaDB is performance, functionality and license: 1. MySQL is developed by Oracle, and MariaDB is its fork. 2. MariaDB may perform better in high load environments. 3.MariaDB provides more storage engines and functions. 4.MySQL adopts a dual license, and MariaDB is completely open source. The existing infrastructure, performance requirements, functional requirements and license costs should be taken into account when choosing.
SQL vs. MySQL: Clarifying the Relationship Between the Two
Apr 24, 2025 am 12:02 AM
SQL is a standard language for managing relational databases, while MySQL is a database management system that uses SQL. SQL defines ways to interact with a database, including CRUD operations, while MySQL implements the SQL standard and provides additional features such as stored procedures and triggers.
How to understand DMA operations in C?
Apr 28, 2025 pm 10:09 PM
DMA in C refers to DirectMemoryAccess, a direct memory access technology, allowing hardware devices to directly transmit data to memory without CPU intervention. 1) DMA operation is highly dependent on hardware devices and drivers, and the implementation method varies from system to system. 2) Direct access to memory may bring security risks, and the correctness and security of the code must be ensured. 3) DMA can improve performance, but improper use may lead to degradation of system performance. Through practice and learning, we can master the skills of using DMA and maximize its effectiveness in scenarios such as high-speed data transmission and real-time signal processing.
MySQL: The Database, phpMyAdmin: The Management Interface
Apr 29, 2025 am 12:44 AM
MySQL and phpMyAdmin can be effectively managed through the following steps: 1. Create and delete database: Just click in phpMyAdmin to complete. 2. Manage tables: You can create tables, modify structures, and add indexes. 3. Data operation: Supports inserting, updating, deleting data and executing SQL queries. 4. Import and export data: Supports SQL, CSV, XML and other formats. 5. Optimization and monitoring: Use the OPTIMIZETABLE command to optimize tables and use query analyzers and monitoring tools to solve performance problems.
How does MySQL differ from Oracle?
Apr 22, 2025 pm 05:57 PM
MySQL is suitable for rapid development and small and medium-sized applications, while Oracle is suitable for large enterprises and high availability needs. 1) MySQL is open source and easy to use, suitable for web applications and small and medium-sized enterprises. 2) Oracle is powerful and suitable for large enterprises and government agencies. 3) MySQL supports a variety of storage engines, and Oracle provides rich enterprise-level functions.
