MySQL添加数据文件 阿里聚石塔服务器,两块硬盘,一块系统盘只有49G,一块数据盘188G,安装MySQL时使用默认配置,因此数据文件放到了系统盘,今天的任务就是把新添加一个数据文件,新的数据文件写入数据盘中。 找到MySQL配置文件/etc/my.cnf innodb_data_home
MySQL添加数据文件阿里聚石塔服务器,两块硬盘,一块系统盘只有49G,一块数据盘188G,安装MySQL时使用默认配置,因此数据文件放到了系统盘,今天的任务就是把新添加一个数据文件,新的数据文件写入数据盘中。
找到MySQL配置文件/etc/my.cnf
innodb_data_home_dir= innodb_data_file_path=/var/lib/mysql/ibdata1:76M;/data/mysql-data/ibdata2:12M:autoextend
?开始只加了innodb_data_file_path,而没有加innodb_data_home_dir,重启mysql服务器一直报错,查看mysql错误文件
1.虽然此处innodb_data_home_dir的配置和默认配置是一样的,但是不能省略,否则报错
2./var/lib/mysql/ibdata1:76M该出大小要和已存在文件的大小一致,否则也会报错。

The main role of MySQL in web applications is to store and manage data. 1.MySQL efficiently processes user information, product catalogs, transaction records and other data. 2. Through SQL query, developers can extract information from the database to generate dynamic content. 3.MySQL works based on the client-server model to ensure acceptable query speed.

Laravel is a PHP framework for easy building of web applications. It provides a range of powerful features including: Installation: Install the Laravel CLI globally with Composer and create applications in the project directory. Routing: Define the relationship between the URL and the handler in routes/web.php. View: Create a view in resources/views to render the application's interface. Database Integration: Provides out-of-the-box integration with databases such as MySQL and uses migration to create and modify tables. Model and Controller: The model represents the database entity and the controller processes HTTP requests.

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.

I encountered a tricky problem when developing a small application: the need to quickly integrate a lightweight database operation library. After trying multiple libraries, I found that they either have too much functionality or are not very compatible. Eventually, I found minii/db, a simplified version based on Yii2 that solved my problem perfectly.

The basic operations of MySQL include creating databases, tables, and using SQL to perform CRUD operations on data. 1. Create a database: CREATEDATABASEmy_first_db; 2. Create a table: CREATETABLEbooks(idINTAUTO_INCREMENTPRIMARYKEY, titleVARCHAR(100)NOTNULL, authorVARCHAR(100)NOTNULL, published_yearINT); 3. Insert data: INSERTINTObooks(title, author, published_year)VA

MySQL efficiently manages structured data through table structure and SQL query, and implements inter-table relationships through foreign keys. 1. Define the data format and type when creating a table. 2. Use foreign keys to establish relationships between tables. 3. Improve performance through indexing and query optimization. 4. Regularly backup and monitor databases to ensure data security and performance optimization.
