下载Mysql对应的安装包；
在mysql目录下配置my-default.ini
# For advice on how to change settings please see # http://dev.mysql.com/doc/refman/5.7/en/server-configuration-defaults.html # *** DO NOT EDIT THIS FILE. It‘s a template which will be copied to the # *** default location during install, and will be replaced if you # *** upgrade to a newer version of MySQL.

二、打开cmd.exe程序的时候选择“用管理员身份打开”。
在mysql的bin目录下面执行： 再输入mysqld install回车运行就行了，注意是是mysqld，不是mysql。
安装成功后，有人直接输入mysql -uroot -p之后然后回车，仍然提示连接不上数据库，这是为何？这是因为安装mysql成功后，还要开启mysql服务才能使用。在任务管理器中打开mysql服务，如果没找到这个服务，先在bin里面运行，mysql.exe
三、修改密码：
格式：mysql> set password for 用户名@localhost = password(‘新密码‘);
例子：mysql> set password for root@localhost = password(‘123456‘);
