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

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")
{

blockNumber: null,

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。
