[mysqld]# 设置3306端口 port=3306# 设置mysql的安装目录 basedir=C:\Program Files\MySQL # 设置mysql数据库的数据的存放目录 datadir=C:\Program Files\MySQL\Data # 允许最大连接数 max_connections=200# 允许连接失败的次数。 max_connect_errors=10# 服务端使用的字符集默认为utf8mb4 character-set-server=utf8mb4 # 创建新表时将使用的默认存储引擎default-storage-engine=INNODB# 默认使用“mysql_native_password”插件认证 #mysql_native_password default_authentication_plugin=mysql_native_password[mysql]# 设置mysql客户端默认字符集default-character-set=utf8mb4[client]# 设置mysql客户端连接服务端时默认使用的端口 port=3306default-character-set=utf8mb4Copy after login
Initialize MySQL. During installation, to avoid permission issues, we try to run CMD as an administrator. , otherwise an error will be reported during installation, which will cause the installation to fail, as shown in the following figure:
After opening, enter the bin directory of mysql, entercd and spaces your path , as shown in the following figure:
Entermysqld --initialize - in the bin directory under the MySQL directory -console, as shown below:
VCRUNTIME140_1.dll. Just download and install this program, as shown below:

Step 7
windows folder, enter the system32 folder, and paste it. After pasting, you will be prompted to require administrator rights, give it to him! !

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.

InnoDB uses redologs and undologs to ensure data consistency and reliability. 1.redologs record data page modification to ensure crash recovery and transaction persistence. 2.undologs records the original data value and supports transaction rollback and MVCC.

Compared with other programming languages, MySQL is mainly used to store and manage data, while other languages such as Python, Java, and C are used for logical processing and application development. MySQL is known for its high performance, scalability and cross-platform support, suitable for data management needs, while other languages have advantages in their respective fields such as data analytics, enterprise applications, and system programming.

MySQL index cardinality has a significant impact on query performance: 1. High cardinality index can more effectively narrow the data range and improve query efficiency; 2. Low cardinality index may lead to full table scanning and reduce query performance; 3. In joint index, high cardinality sequences should be placed in front to optimize query.

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 is suitable for web applications and content management systems and is popular for its open source, high performance and ease of use. 1) Compared with PostgreSQL, MySQL performs better in simple queries and high concurrent read operations. 2) Compared with Oracle, MySQL is more popular among small and medium-sized enterprises because of its open source and low cost. 3) Compared with Microsoft SQL Server, MySQL is more suitable for cross-platform applications. 4) Unlike MongoDB, MySQL is more suitable for structured data and transaction processing.

InnoDBBufferPool reduces disk I/O by caching data and indexing pages, improving database performance. Its working principle includes: 1. Data reading: Read data from BufferPool; 2. Data writing: After modifying the data, write to BufferPool and refresh it to disk regularly; 3. Cache management: Use the LRU algorithm to manage cache pages; 4. Reading mechanism: Load adjacent data pages in advance. By sizing the BufferPool and using multiple instances, database performance can be optimized.

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.
