MySQL8.0 Windows zip包下载地址：https://cdn.mysql.com//Downloads/MySQL-8.0/mysql-8.0.11-winx64.zip
环境：Windows 10
1
1. 解压zip包到安装目录
比如我的安装目录是：D:\Program\MySQL
2.配置文件
在Windows系统中，配置文件默认是安装目录下的 my.ini 文件，部分配置需要在初始安装时配置，大部分也可以在安装完成后进行更改。当然，极端情况下，所有的都是可以更改的。
在安装根目录下添加 my.ini，比如我这里是=F:\mysql\mysql-8.0.11-winx64 ，写入基本配置：
[mysqld]
port=3306
basedir =F:\mysql\mysql-8.0.11-winx64
datadir =F:\mysqlData\
max_allowed_packet = 32M
3.初始化数据库
在MySQL安装目录的 bin 目录下执行命令：
mysqld --initialize --console
执行完成后，会打印 root 用户的初始默认密码，比如：
