网上看了多信息仍未解决，最终去官网上找到了原因，原来data目录是我手工创建的，还必须执行如下命令进行初始化。
http://dev.mysql.com/doc/refman/5.7/en/windows-extract-archive.html
http://dev.mysql.com/doc/refman/5.7/en/data-directory-initialization-mysqld.html
To initialize the data directory, invoke mysqld with the --initialize or --initialize-insecure option, depending on whether you want the server to generate a random initial password for the 'root'@'localhost' account.
On Windows, use one of these commands:
C:>binmysqld --initializeC:>binmysqld --initialize-insecure 这个命令会创建空密码的 root@localhost 账号，否则会创建带密码的 root@localhost 账号，密码直接写在 log-error 日志文件中
执行完这命令，
再执行 mysqld install MySQL --defaults-file="D:Program FilesMySQLmysql-5.6.13-win32my.ini"
果然mysql服务就正常启动了。
记录下安装步骤：
添加环境变量
变量名：MYSQL_HOME
变量值：D:Program Filesmysql-5.6.14-winx64
即为mysql的自定义解压目录。
再在Path中添加 %MYSQL_HOME%in
添加为服务：
从控制台进入到MySQL解压目录下的 bin 目录下：
binmysqld --initialize-insecure
输入服务安装命令：
mysqld install MySQL --defaults-file="D:Program FilesMySQLmysql-5.6.13-win32my.ini"
#解压目录下修改的my.ini文件
安装成功后会提示服务安装成功。
#注：my.ini文件放在MySQL解压后的根目录下
#移除服务命令为：mysqld remove
附上myini文件：
[client]
port=3306
default-character-set=utf8
[mysqld]
port=3306
character_set_server=utf8
#解压目录
basedir=C:MySqlmysql-5.7.10-winx64
#解压目录下data目录
datadir=C:MySqlmysql-5.7.10-winx64data
#没有这行在5.7中要这行，否则初始化时会有警告： [Warning] TIMESTAMP with implicit DEFAULT value is deprecated. Please use --explicit_defaults_for_timestamp server option (see doc umentation for more details).
explicit_defaults_for_timestamp=true
