1.下载
https://downloads.mysql.com/archives/community/
2. 创建my.ini文件。复制如下文档
[mysqld]
character-set-server=utf8
bind-address = 0.0.0.0
port = 3306
basedir=D:/mysql-5.7.24-winx64
datadir=D:/MySQL_Data_DFN_FT/data
max_connections=2000
default-storage-engine=INNODB
[mysql]
default-character-set=utf8
[mysql.server]
default-character-set=utf8
[client]
default-character-set=utf8
3. 拷贝到解压目录
4.添加环境变量
管理员方式运行CMD，安装服务。mysqld --install mysql
5. 初始化data文件夹，mysqld --initialize --user=root --console，（如何设置mysql的默认密码）
my.ini中：datadir=D:/MySQL_Data_DFN_FT/data，自己先创建MySQL_Data_DFN_FT的目录，data文件就会自动生成到这里。
自动生成root,的登录密码。
6. 启动服务， net start mysql
C:WINDOWSsystem32>net start mysql
mysql 服务正在启动 .
mysql 服务已经启动成功。
7. 登录root用户。mysql -uroot -pafyysw,7exwG
C:WINDOWSsystem32>mysql -uroot -pafyysw,7exwG
