官网下载并解压mysql-5.7.25-winx64.zip，然后配置环境变量

在解压的目录下创建data文件夹用于存放数据，再创建my.ini配置文件，内容如下:

[mysqld]

#设置3306端口

port = 3306

# 设置mysql的安装目录

basedir=F:\\software-school\\mysql-5.7.25

# 设置mysql数据库的数据的存放目录

datadir=F:\\software-school\\mysql-5.7.25\\data

# 允许最大连接数

max_connections=200

# 服务端使用的字符集默认为8比特编码的latin1字符集

character-set-server=utf8

# 创建新表时将使用的默认存储引擎

default-storage-engine=INNODB

注意: 这里文件目录要使用双斜杠

以管理员权限打开cmd窗口，输入以下命令

1、mysqld --initialize --user=mysql --console 初始化数据库，在data目录里生成数据文件，会生成一个默认密码,复制好密码, 以便待会儿修改密码：

C:\WINDOWS\system32>mysqld --initialize --user=mysql --console
