mysql5.7.13.zip安装（windows）

ddlddx0000

　　按照我之前安装5.6的安装方法（MySQL免安装版下载与配置）安装5.7的时候出现问题：
　　mysql服务无法启动，服务没有报任何错误
　　
　　其实在这学期开始学习mysql的时候，就听老师同学说，登录不了的问题，当时没有在意，也是因为电脑上早就安装了mysql5.6，也就没有在意这个问题。这两天win10系统出问题，重装了win7，安装5.7的时候出现了这个问题。
　　之前的版本默认密码为空，具体版本不太清楚，反正5.6密码是空。5.7的安全性提升，在linux安装5.7的时候，安装完成后会生成一个随机性密码，存储在root/.mysql_secret中，如果没有这个文件，去系统日志中查找password，就应该能找到。
　　但是windows下就不知道如何解决了，不过最后还是找到了解决方法。
　　解决方法：
　　来自：windows MySql 5.7.9，启动不了。缺少data
　　然而并不是缺少data文件夹，将my-default.ini文件改名为my.ini，移动到bin/目录下，在bin/下执行命令 mysqld --initialize --user=mysql --console ，这条命令估计是初始化的命令
　　然后启动服务 net start mysql
　　命令行显示贴在这
