当把本地数据库作为服务器的时候，如果你发现client无法链接到你的数据库服务器，那么有可能是：
1. 当前account没有远程链接权限，如何开通？
GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'password' WITH GRANT OPTION;
FLUSH PRIVILEGES;
2. 防火墙屏蔽了远程链接请求，怎么解决？
netsh advfirewall firewall add rule name="MySQL Server" action=allow protocol=TCP dir=in localport=3306
