我用的是一台学校发的电脑（ip:），一台自己的笔记本
1.查询两台电脑的IP

3.两台电脑用同一个创世区块

记住这个节点的值
5.将节点加入私链，并查询
将笔记本节点加入台式机节点
admin.addPeer("enode://0d1d38a234a12c4d2726c2852ecc3735acfb5da0e223251516025825dfacf7217b3dce11490716f0a29c563714f4a8ada4e550f59ce3f0e3010fcf7f4a6fc572@10.173.40.12:1111?discport=0")然后查询结果：

}
}
}]

1同理，台式机节点加入笔记本的私链
admin.addPeer("enode://902d5ae2ac8f3707becc83050a8b4cd5e32bd82ff8c911896cbdfb875b0b83dcdb898caad6b1c7c842b079e2fdea1f0fa74cb9abda0fab5ab634a85ae7090191@192.168.235.46:1111?discport=0")
