下载解压不说
我解压在：E:/DBFiles/mysql-5.7.15-winx64/mysql-5.7.15-winx64
添加配置文件E:/DBFiles/mysql-5.7.15-winx64/mysql-5.7.15-winx64/my.ini

在zip包中已经不含data目录，需要初始化一下：mysqld --initialize
然后进行服务注册：E:/DBFiles/mysql-5.7.15-winx64/mysql-5.7.15-winx64/bin>mysqld install MySQL --defaults-file="E:/DBFiles/mysql-5.7.15-winx64/mysql-5.7.15-winx64/my.ini"
提示安装成功
服务成功注册之后，启动MySQL服务，MySQL服务可以成功启动，可以用root用户登录的时候提示要求输入密码，此时还没有设置root密码
停止服务，在my.ini中加一个skip-grant-tables=1的配置，允许跳过密码，修改过后重启MySQL服务，root用户可以正常登录
登录之后修改密码，利用alter user root identitied by 'root'的方式修改
提示：The MySQL server is running with the --skip-grant-tables option so it cannot execute this statement
然后参考网上，用：update user set authentication_string=PASSWORD('root') where User='root';可以修改成功
通过update user set authentication_string=password('root') where user ='root'的方式修改密码，提示成功
