Download mysql-5.7.19-winx64 from the official website. Note that it corresponds to the system 64-bit or 32-bit. Here we use 64-bit.

Unzip the file and save it to a local disk. I found that the file was very large, about 1.6G. Delete the .lib files in the lib folder and all files in the debug folder.

Create a my.ini file in the home directory. The content of the file is as follows: (This is a simplified version, corresponding to the local modification of the basedir and datadir directories. You can expand the configuration yourself as needed)

[client]
port=3306
default-character-set=utf8 
[mysqld] 
basedir=D:\JavaTools\mysql-5.7.19-winx64
datadir=D:\JavaTools\mysql-5.7.19-winx64\data
port=3306
character-set-server=utf8
character-set-filesystem = utf8
sql_mode=NO_ENGINE_SUBSTITUTION,NO_AUTO_CREATE_USER
explicit_defaults_for_timestamp=true
skip-grant-tables

4. The free installation version has no data files, so you need to create a data folder yourself. Here we start to pay attention to the order of commands

5. Install mysql service.

6. Start mysql

Very important: set the root user's password, the above is a password-free login

Enter the mysql environment, mysql -u root

Change the password, alter user root@localhost identified by "12345";
