What I installed here is MySQL 5.7.43. The following is a detailed download, installation and configuration tutorial.

1. Download steps

1. Enter the official website: https://www.mysql.com/
2. Scroll to the bottom of the homepage and find MySQL Community server
3. Select the version you want and the corresponding computer configuration to download.
   
4. After downloading, unzip it to the directory you want to save.

2. Configure environment variables

1. Right-click this computer->Properties->Advanced system settings->Environment variables->System variables

2. Create a new system variable

Variable name: MYSQL_HOME
Variable value: D:\MySQL\mysql-5.7.43-winx64

3. Add the newly created system variable to Path

%MYSQL_HOME%\bin

4. Configure the my.ini file.
Create a new my.ini file.

The contents of the my.ini file:

[mysqld]
#端口号
port = 3306
#mysql-5.7.43-winx64的路径
basedir=D:\MySQL\mysql-5.7.43-winx64

5. Install MySQL
① Enter cmd in the search box and run as administrator
② Enter the MySQL installation directory D:\MySQL\mysql-5.7.43-winx64 in cmd

and enter the installation command: mysqld -install . If Service successfully installed appears, it is proved The installation is successful; if Install of the Service Denied appears, it means that cmd is not running with administrator privileges:

continue to enter the command: mysqld --initialize to initialize the database
and then enter the startup command: net start mysql . The following prompt appears to prove that MySQL is started successfully:

6.Set MySQL password

1. Setting the password is mainly used to solve the problem of ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: NO)
2. To stop the MySQL service, enter the command line net stop mysql :
3. Find the my.ini file you just created and add skip-grant-tables
4. Restart MySQL through the command net start mysql
5. Then enter the command mysql -u root -p . There is no need to enter a password. Just press Enter to enter MySQL.
6. Enter the command line use mysql , enter the database,
   and then enter the command line to change your MySQL password:
   update user set authentication_string=password("ping1212") where user="root";
   
   7. Stop the MySQL service and enter service in the system search box. Find MySQL. Just right-click and click Stop. 8. Then delete skip-grant-tables
   
   
   in the my.ini file just now , start cmd again (as administrator), enter the startup command: net start mysql , then enter mysql -u root -p , and then enter the value you just set Password, the following information appears to prove that the setting is successful! 9. Enter the command use mysql , and it will prompt that you need to reset the password. 10.
