MAC 以太坊环镜安装

安装步骤以下：

一、下载GO语言安装包：https://storage.googleapis.com/golang/go1.10.darwin-amd64.pkg

GO语言开发环境参考
http://www.javashuo.com/article/p-fmysmcus-b.html

二、安装以太坊

brew install ethereum

三、钱包下载页面：

==Mac以太坊构建本地私有网络 https://segmentfault.com/a/1190000013635759==

经常使用命令

＃开发
geth --dev 

#全部用户信息
personal.listAccounts
#解锁用户
personal.unlockAccount(eth.accounts[0])

＃查询当前获取币的账户
eth.coinbase
# 查询区块高度
eth.blockNumber
#查询全部账户信息
eth.accounts
# 查询账户金额
eth.getBalance(eth.accounts[0])
#友好显示账户金额
web3.fromWei(eth.getBalance(eth.accounts[0]),"ether")
＃请求交易
eth.sendTransaction({from: "0x4008c676edcd32167d751ff8034eba8722ff9442", to: "0x0076b9c28a1ef05e85d59369c4410a097e6a1437", value: web3.toWei(1, "ether")})
另一种语法
eth.sendTransaction({from: eth.accounts[0], to: eth.accounts[1], value: web3.toWei(1, "ether")})



#设置挖矿获取收益账户
miner.setEtherbase(eth.accounts[1])

# MAC 钱包打开私有链 /workspace/ethereum/gw/geth.ipc 私有链地址
./Ethereum\ Wallet.app/Contents/MacOS/Ethereum\ Wallet --rpc "/workspace/ethereum/gw/geth.ipc"

本机开发命令整理

#启动
geth --datadir="/workspace/ethereum/my" --dev  console 2>> b

问题及解决方法

==问题：001　tag:链接==

<!--命令-->
geth attach http://10.8.42.91:8545
<!--报错-->
Fatal: Failed to start the JavaScript console: api modules: Post http://10.8.42.91:8545: context deadline exceeded


====解决方法====
关闭91服务器防火墙

==问题：002　tag:初始化==

<!--命令-->
geth --datadir "/workspace/ethereum/gw" init genesis.json
<!--报错-->
Failed to write genesis block: genesis has no chain configuration

解决方法：修改genesis.json，增长config节点。

修改后内容以下(genesis.json)：

{
  "config": {
    "chainId": 10,
    "homesteadBlock": 0,
    "eip155Block": 0,
    "eip158Block": 0
  },
  "nonce": "0x0000000000000042",
  "timestamp": "0x0",
  "parentHash":"0x0000000000000000000000000000000000000000000000000000000000000000",
  "gasLimit": "0x80000000",
  "difficulty": "0x400",
  "mixhash":"0x0000000000000000000000000000000000000000000000000000000000000000",
  "coinbase": "0x3333333333333333333333333333333333333333",
  "alloc": {
  }
}
