mysql-5.7.20-winx64安装教程

1.下载解压

下载mysql-5.7.20-winx64.zip并解压缩，链接：https://pan.baidu.com/s/1c2CUMI0 密码：ssst，本文解压到D:\Program Files\mysql-5.7.20-winx64

2.环境变量

系统变量配置MYSQL_HOME以及Path

3.my.ini配置

在解压目录下找到bin目录，并且新增my.ini文件，文件内容如下

[client]default-character-set=utf8[mysqld] port=3306 basedir=%MYSQL_HOME%datadir=%MYSQL_HOME%\data character-set-server=utf8 default-storage-engine=INNODB[mysql] default-character-set=utf8

4.cmd操作

以系统管理员身份运行cmd，依次执行命令
cd进入到bin目录（不知道为啥没进入目录的时候，后面无法启动服务）
初始化数据库，不生成随机密码（会在mysql目录生成data目录，如果已经有data目录了那就先手动删除）
安装mysql服务
启动mysql服务
初始化root用户密码为123456
尝试登陆mysql
