demo/dpos can not run 2 miners at the same time

[ganioc]

Problem:
我在测试中发现demo/dpos例子，无法运行2个miner节点。理论上应该在Node1运行后，Node2能够接收到Node1广播的出块信息，但是没有。

Node1

Environment:
Ubuntu 16.04 server Node1, Node 2
使用了自己的SN server

Test Steps:
Node1
(1) ./demo/dpos/create.sh
(2)./demo/dpos/miner.sh
Node2
(3)./demo/dpos/create.sh
(4)./demo/dpos/miner2.sh

Scripts:
脚本中，除了更改miner.cfg里的"sn"外，没有变化。

node2不能再create创始块了，需要用node1的创世块，否则是两个独立的链

好的。会测试并返回测试结果。
谢谢！

This is the data/ directory on Node 1 after running ./create.sh , what should be copied to Node 2?
