一、安装准备
mysql-5.6.37-winx64下载
二、安装mysql
1.解压mysql-5.7.11-win32.zip 到 c:\mysql-5.7.11-win32
2.设置环境变量 MYSQL_HOME=c:\mysql-5.7.11-win32, path=%MYSQL_HOME%\bin
3.关键一步是my.ini的设置，我的是

4. 管理员身份进入cmd(以下都是)
5.mysqld --install MySQL --defaults-file=D:\software\mysql-5.6.37-winx64\my.ini 安装mysql服务
6.mysqld --initialize 这是生成data目录及初始化数据
7.启动服务net start mysql 或在服务中启动
9. mysql -uroot -p登录mysql
输入初始密码连接进入mysql数据库后，修改密码如下：
set password=password('123456');
flush privileges;
退出再次登录，使用新密码就行了：
mysql -uroot -p123456
