环境：Mac10.11

1、安装homebrew

/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

注意：这个比较大，可能要稍等一会

2、安装以太坊客户端geth

brew tap ethereum/ethereumbrew install ethereum

3、在/usr/local下建myehtereum文件夹

mkdir myethereum

4、将genesis.json放在其中，内容如下

{  "config": {    "chainId": 33,    "homesteadBlock": 0,    "eip155Block": 0,    "eip158Block": 0  },  "nonce": "0x0000000000000033",  "timestamp": "0x0",  "parentHash": "0x0000000000000000000000000000000000000000000000000000000000000000",  "gasLimit": "0x20000",  "difficulty": "0x1",  "mixhash": "0x0000000000000000000000000000000000000000000000000000000000000000",  "coinbase": "0x0000000000000000000000000000000000000000",  "alloc": {}}

5、初始化私有链

geth --datadir "privateChain" init genesis.json

6、进入控制台

geth --datadir "privateChain" console

注意：执行完会出现一个>

7、创建2个账号

personal.newAccount("12345678")personal.newAccount("87654321")

2个账号的地址分别是"0xe727467a74cb257f6a37fec04671d31494b6d721"，

"0xee6cf7e7b16393d57ab54bb867bcdb4c6d965a95"

8、分别给这2个私钥用变量表示

addr0="0xe727467a74cb257f6a37fec04671d31494b6d721"addr1="0xee6cf7e7b16393d57ab54bb867bcdb4c6d965a95"

如下图所示：

9、开始挖矿

miner.start();admin.sleepBlocks(1);miner.stop();

注意：第一次挖矿非常慢，需要约半小时，再2次再挖矿时就快很多了，关键字如下

Generating ethash verification cache

Generating DAG in progress

如下图所示

10、查看一下账户余额

web3.eth.getBalance(addr0)

结果如下

10000000000000000000

11、地址1给地址2转账（需挖矿后才能生效）

amount=web3.toWei(1)personal.unlockAccount(addr0)eth.sendTransaction({from:addr0,to:addr1,value:amount})

注意：需要先解锁账户
