以太坊私链转账挖矿后仍然不成功，请高手指教；私链启动后ip不是127.0.0.1，不确定是否是这个原因，如果是这个原因怎么解决？

具体操作步骤
一、配置创世区块

{
	"config":{"chainId":15},
	"difficulty":"2000",
	"gasLimit":"2100000",
	"alloc":{
		"AD9E4555F515132aa94626555A14cdff1e86F0df":{"balance":"300000"}
	}
}

二、启动私链

geth --datadir . --networkid 15  console 2>output.log

启动信息如下：

    }
  }
}

三、创建了两个账户，通过挖矿都有以太

> web3.fromWei(eth.getBalance(eth.accounts[0]))
1200
> web3.fromWei(eth.getBalance(eth.accounts[1]))
570

四、估计交易 gas 消耗，转账（期间账户解锁成功）生成交易 hash

> eth.estimateGas({from:eth.accounts[0],to:eth.accounts[1],value:web3.toWei(10,'ether')})
21000
> eth.sendTransaction({from:eth.accounts[0],to:eth.accounts[1],value:web3.toWei(10,'ether')})
"0x5a3687165263503df5d38db988c0e8c294f3ea2c9999fb13ef39bebbc3e2b529"

五、挖矿

> miner.start(1)
null

log 信息

INFO [12-16|20:18:58.564] Submitted transaction                    fullhash=0x5a3687165263503df5d38db988c0e8c294f3ea2c9999fb13ef39bebbc3e2b529 recipient=0x55Db8f37a9c6C226cf2eaf88874E68267aDa9fbE

六、查看收款账户余额

> web3.fromWei(eth.getBalance(eth.accounts[1]))
570
收款账户没收到转账，以太没有变化

七、查看交易信息

> eth.getTransaction("0x5a3687165263503df5d38db988c0e8c294f3ea2c9999fb13ef39bebbc3e2b529")
{
  blockHash: null,
  blockNumber: null,
  from: "0x960e9241a17c7e095e8480870d4d381e8a550163",
  gas: 21000,
  gasPrice: 1000000000,
  hash: "0x5a3687165263503df5d38db988c0e8c294f3ea2c9999fb13ef39bebbc3e2b529",
  input: "0x",
  nonce: 3,
  r: "0x842ec6a9e84e0c782660a6f113159f920c4a4434f5d3fe658b7df3394be1489",
  s: "0x112e3958f814401e6f0681787b689595e7c0150b7176ab23ef97cdacffbb7541",
  to: "0x55db8f37a9c6c226cf2eaf88874e68267ada9fbe",
  transactionIndex: null,
  v: "0x42",
  value: 10000000000000000000
}

八、其它说明
（1）在 geth --datadir . --dev console 2>output.log 下可以转账，启动后 ip 是 127.0.0.1。
（2）在 geth --datadir . --networkid 15 --rpc console 2>output.log 转账也是无法成功。
