【第一步】下载mysql非安装解压包mysql-8.0.33-winx64.zip，解压到本地（C:\MySql\mysql-8.0.33）网址：https://dev.mysql.com/downloads/file/?id=518220；
【第二步】解压到本地，配置环境变量：双击此电脑（进入）—> 空白处右击，选择属性—>点击高级系统设置—>点击环境变量（进入）—>编辑用户变量Path—>添加mysql的bin路径（我的解压路径是C:\MySql\mysql-8.0.33，path添加 C:\MySql\mysql-8.0.33\bin）；
【第三步】C:\MySql\mysql-8.0.33路径下新建my.ini文件，编辑内容如下：
[client]
#客户端端口号为3306
port=3306
default-character-set=utf8
[mysqld]
basedir=C:\MySql\mysql-8.0.33\
datadir=C:\MySql\mysql-8.0.33\data\
port=3306
shared-memory
skip-grant-tables
# skip-grant-tables：跳过用户验证
# basedir和datadir需要手动改为自己实际的路径
【第四步】初始化mysql
C:\Users\Administrator>cd C:\MySql\mysql-8.0.33-winx64\bin
C:\MySql\mysql-8.0.33-winx64\bin> mysqld install
C:\MySql\mysql-8.0.33-winx64\bin>net start mysql
MySQL 服务正在启动 .
MySQL 服务已经启动成功。
mysql> alter user 'root'@'localhost' identified by '123456';
ERROR 1290 (HY000): The MySQL server is running with the --skip-grant-tables option so it cannot execute this statement
mysql> flush privileges;

mysql> alter user 'root'@'localhost' identified by '123456';

mysql> flush privileges;
Query OK, 0 rows affected (0.04 sec)
C:\MySql\mysql-8.0.33\bin>net stop mysql
MySQL 服务正在停止.
MySQL 服务已成功停止。
【第五步】注释掉my.ini文件中的skip-grant-tables
C:\MySql\mysql-8.0.33\bin>net start mysql
MySQL 服务正在启动 .
MySQL 服务已经启动成功。
C:\MySql\mysql-8.0.33\bin>mysql -u root -p
Enter password: ****** （上边设置的密码 123456）
