1. 将配置文件my.ini配置好，放到c:/windows目录下 （echo %windir%),然后执行安装mysql默认数据库的操作：

D:\tools\mysql-5.7.9-winx64\bin>mysqld --initialize-insecure --user=mysql

2. 将mysql安装成windows中的服务：

D:\tools\mysql-5.7.9-winx64\bin>mysqld install
Service successfully installed.

3. 然后在services.msc中启动mysql服务。

4.允许root访问，并且设置了root在192.168.0.101访问过来的密码，并且赋予root授予其他用户权限的权利。（权限传递 使用这个子句时将允许用户将其权限分配给他人）
mysql> grant all on *.* to "root"@"192.168.0.101" identified by "root"  WITH GRA
NT OPTION;
Query OK, 0 rows affected, 1 warning (0.00 sec)

mysql> flush privileges;
Query OK, 0 rows affected (0.01 sec)

5. 官方的windows安装文档：
