mysql5.7.13的安装与配置（windows）

先到官网下载与系统对应的mysql5.7.13 zip版本，解压到C:\Program Files\mysql\文件夹下,然后只需要简单配置就可以了

先配置环境变量，新建MYSQL_HOME,值为C:\Program Files\mysql\mysql-5.7.13-winx64\mysql-5.7.13-winx64

然后选择Path,在后面添加%MYSQL_HOME%\bin（注意用分号隔开）。然后在C:\Program Files\mysql\mysql-5.7.13-winx64\mysql-5.7.13-winx64文件夹下新建my.ini文件（my.ini文件目录地址需要改成自己的地址），如下图：

然后以管理员模式打开cmd，进入到bin文件夹里面：

，

执行mysqld --initialize,执行过程中需要等待一会儿，这时候bin同级目录下会出现一个data文件夹（如果data文件夹中有文件，应该先删除再执行mysqld --initialize），

然后执行mysqld -install,

继续执行net start mysql，这时候mysql服务就启动了。

如果mysql无法启动又不报错误，原因是要先删除data文件夹，再执行mysqld --initialize。还有可能重启一下电脑就可以（我就是这原因，可能是3306端口被占用了吧）
