introduction

MySQL 5.7 is the MySQL version commonly used by companies and enterprises.
Friends who are studying or working recommend relevant tutorials to learn and operate according to version 5.7.

1. Download MySQL

• Alibaba cloud disk unlimited speed download address: https://www.aliyundrive.com/s/YTMa5LfSFB2

Because Alibaba Cloud Disk does not support the sharing of zip archives, I used the 7z tool to create self-extracting archives. Double-click to run the exe to decompress

• Official website download address: https://dev.mysql.com/downloads/mysql/
  
  Decompressed file directory structure: (After decompressing, you can change the name of the folder, for example, I changed it to: MySQL)
  

2. Initialize the my.ini file

Create the my.ini file in the MySQL unzipped directory. (If you don’t know how to create it, you can also download the finished product here: https://www.aliyundrive.com/s/YTMa5LfSFB2 )
