一、下载
MySQL官网下载链接:https://downloads.mysql.com/archives/community/
选择版本后下载zip文件
博主选择的是8.0.13
二、安装
1 解压
把下载好的zip包在你想要的路径下直接解压。
解压完成后得到这个界面:
2 配置环境变量
右击此电脑选择属性
双击系统环境变量的Path
新建一个刚刚你解压的路径(注意要到bin路径下)
3 配置my.ini
在D:\Program Files (x86)\mysql-8.0.13-winx64\mysql-8.0.13-winx64路径下新建一个 my.ini 文件。
这里有一个注意点:如果出现mysql8.0安装报错 error: Found option without preceding group in config file:
则把ini文件另存为ANSI编码
文件内容如下:
[mysqld] # 设置3306端口 port=3306 # 设置mysql的安装目录 basedir=D:\\Program Files (x86)\\mysql-8.0.13-winx64\\mysql-8.0.13-winx64 # 切记此处一定要用双斜杠\\,单斜杠这里会出错。 # 设置mysql数据库的数据的存放目录 datadir=D:\Program Files (x86)\mysql-8.0.13-winx64\\Data # 此处同上 # 允许最大连接数 max_connections=200 # 允许连接失败的次数。这是为了防止有人从该主机试图攻击数据库系统 max_connect_errors=10 # 服务端使用的字符集默认为UTF8 character-set-server=utf8 # 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 default_authentication_plugin=mysql_native_password [mysql] # 设置mysql客户端默认字符集 default-character-set=utf8 [client] # 设置mysql客户端连接服务端时默认使用的端口 port=3306 default-character-set=utf8
4 命令行启动mysql
WIN+R 输入cmd 进入window命令行
cd 进入安装mysql的bin目录下
输入:mysqld --initialize --console
等待片刻会输出一堆东西,推荐先把这些输出复制一下,放到一个记事本里,因为里面会有你需要的数据库初始密码。
一般会在root@localhost:之后(是一堆像乱码一样的东西,这是初始的随机密码,后续我们会进行更改!)
记下密码之后,执行命令:mysqld --install
安装mysql
正常会输出 successfully
之后执行命令:net start mysql
启动mysql服务
5 修改登录密码
命令:mysql -u root -p
之后复制你刚刚保存在txt文件的初始密码进入mysql
命令:alter user root@localhost identified by '123456'
; 这个 123456是我随便打的 可以自定义修改,如果是mysql8以上,推荐别使用纯数字密码,别问我为什么,都是被坑出来的教训!
注:如果出现忘记初始随机密码的情况,可以重新执行mysqld --initialize --console
这个命令,但是前提是删除之前生成的Data文件夹

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.

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 is worth learning because it is a powerful open source database management system suitable for data storage, management and analysis. 1) MySQL is a relational database that uses SQL to operate data and is suitable for structured data management. 2) The SQL language is the key to interacting with MySQL and supports CRUD operations. 3) The working principle of MySQL includes client/server architecture, storage engine and query optimizer. 4) Basic usage includes creating databases and tables, and advanced usage involves joining tables using JOIN. 5) Common errors include syntax errors and permission issues, and debugging skills include checking syntax and using EXPLAIN commands. 6) Performance optimization involves the use of indexes, optimization of SQL statements and regular maintenance of databases.

MySQL is suitable for beginners to learn database skills. 1. Install MySQL server and client tools. 2. Understand basic SQL queries, such as SELECT. 3. Master data operations: create tables, insert, update, and delete data. 4. Learn advanced skills: subquery and window functions. 5. Debugging and optimization: Check syntax, use indexes, avoid SELECT*, and use LIMIT.

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.

MySQL is an open source relational database management system that is widely used in Web development. Its key features include: 1. Supports multiple storage engines, such as InnoDB and MyISAM, suitable for different scenarios; 2. Provides master-slave replication functions to facilitate load balancing and data backup; 3. Improve query efficiency through query optimization and index use.

SQL is used to interact with MySQL database to realize data addition, deletion, modification, inspection and database design. 1) SQL performs data operations through SELECT, INSERT, UPDATE, DELETE statements; 2) Use CREATE, ALTER, DROP statements for database design and management; 3) Complex queries and data analysis are implemented through SQL to improve business decision-making efficiency.

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
