在上一篇文章中搭建好了私有链之后，开始进行一些 简单的操作。

 

终端运行：

@>>  geth  --datadir "./chain" --nodiscover console 2>>eth_output.log

启动geth

//给自己的两个账户重命名。
> user1 = eth.accounts[0]
"0xfd5db5967bb4600840adde5035b8de4d56176ad5"
> user2 = eth.accounts[1]
"0xa740690de331a76519133175c3f28aeb865de658"

//查看用户1的ETH
> eth.getBalance(user1)
5.93e+21
> eth.getBalance(user2)
0

//解锁，转账之前必须解锁操作。
> personal.unlockAccount("0xfd5db5967bb4600840adde5035b8de4d56176ad5","123456")
true

//将用户1给用户2转3个ETH
> eth.sendTransaction({from: user1, to: user2, value: web3.toWei(3, "ether")})
"0xf9c613bf8dadc0b18574ab019add49e9d75f9fd33fbac0fb9cb8f50266d0cbee"

//然后查看用户2的名下还是0个ETH
> eth.getBalance(user2)
0

//打开挖矿
> miner.start()
null

//在转一次帐
> eth.sendTransaction({from: user1, to: user2, value: web3.toWei(3, "ether")})
"0xf9c613bf8dadc0b18574ab019add49e9d75f9fd33fbac0fb9cb8f50266d0cbee"

//查看用户2的余额 ，发现有6个ETH了。
> eth.getBalance(user2)
6000000000000000000
