1.可能原因：由于安装的mysql拒绝外部连接

　　修改方法，依次执行以下三句话：就可以开放权限，让外部机器连接（需要修改第二句中的username和password）

　　mysql>update user set host = '%' where user='root';

　   mysql>grant all privileges on *.* to 'usename'@'%' identified by 'password' with grant option;

　　mysql>FLUSH   PRIVILEGES;

可能原因：由于mysql中配置的最大线程池太少，需要修改大一些

 找到本地mysql的安装目录：修改my.ini  文件
