以太坊win平台和Linux 私链搭建，交易，添加多节点

先上一篇的以太坊的私有搭建，交易，节点连接，结合搭建的步骤对以太坊进行深入介绍。本文介绍的方式在win10 和ubuntu16.04 的方式测试过。
第一步：geth的安装，请直接移步：https://github.com/ethereum/go-ethereum/wiki/Building-Ethereum
或者百度其他博客。为了方便操作，windows 平台在安装完成geth后，最好将geth.exe 所在的目录添加到Path环境变量中以便于开发。linux 的方式推荐使用ppa的方式安装。如果不是也推荐奖geth 添加到环境变量里面。
第二步：创建创世块
先不要想太多直接复制我的创世块用:
新建一个文件夹名为mynode，然后在mynode 文件夹里面创建一个文件

{
"config": {
        "chainId": 10,
        "homesteadBlock": 0,
        "eip155Block": 0,
        "eip158Block": 0
    },
  "nonce": "0x0000000000000042",
  "timestamp": "0x00",
  "parentHash": "0x0000000000000000000000000000000000000000000000000000000000000000",
  "extraData": "0x00",
  "gasLimit": "0x80000000",
  "difficulty": "0x01",
  "mixhash": "0x0000000000000000000000000000000000000000000000000000000000000000",
  "coinbase": "0x3333333333333333333333333333333333333333",
  "alloc": {     }
}

如果初始化出错请，检查json配置文件是否正常。为了避免各种错误，请直接复制我上面的genesis.json
第三步：打开控制台

geth --datadir "/newhome/blockchain/geth/mynode"  --nodiscover console

运行结果

常用命令介绍：
查看账户：eth.accounts

["0x45144978abe0e0bbfc187853c8dcef117fa86f89", "0xcad5cc7224b44db9192ef20e9e4263140fa0c1aa"]

创建账户，第一种方式：

 web3.personal.newAccount("mu123456")

账户地址 : "0x79e27b1c9ce1ae7c7d51ee69fa6b2178af3c844e”

其中 mu123456 是密码，0x79e27b1c9ce1ae7c7d51ee69fa6b2178af3c844e 是账户

第二个账户：
用第二种方式创建

web3.personal.newAccount()
Passphrase: 
Repeat passphrase: 
"0x041fca7a8bbf27ee9a7b8300f31306210ce7da10"

查看账户余额：

web3.eth.getBalance(eth.accounts[0])

或者

eth.getBalance(eth.accounts[0])

或者

web3.eth.getBalance("0x74bb4ae9816788a6f81621b177096c2ecad075f2")

或者以“wei”展示：

web3.fromWei(web3.eth.getBalance(web3.eth.accounts[0]),"ether")

挖矿
在js console 输入：
启动挖矿：miner.start()
停止挖矿：miner.stop()
查看是否正在挖矿中：eth.mining
查看节点信息：

> admin

运行结果：

{
  datadir: "/newhome/blockchain/geth/mynode",
  nodeInfo: {
    enode: "enode://29af54c8bbc87acf38f2b259966a1c54ef25d5293c8b447080cbd8bd18fb3fc06e692c43a7ea8011708f217776420cc48fb8ef5d5aa3bcf39528a52963b0a8f2@[::]:30303?discport=0",
    id: "29af54c8bbc87acf38f2b259966a1c54ef25d5293c8b447080cbd8bd18fb3fc06e692c43a7ea8011708f217776420cc48fb8ef5d5aa3bcf39528a52963b0a8f2",
    ip: "::",
    listenAddr: "[::]:30303",
    name: "Geth/v1.8.2-stable-b8b9f7f4/linux-amd64/go1.9.4",
    ports: {
      discovery: 0,
      listener: 30303
    },
    protocols: {
      eth: {
        config: {...},
        difficulty: 27131985,
        genesis: "0x6099b65e564bd511f49e8f39ba27b6a68b6b78fd1481592257f06bbf93abe624",
        head: "0x39196960b218ff5638ca990750dae49c47bcf14ea2c52a77aec37d26cc1c0084",
        network: 1
      }
    }
  },
  peers: [],
  addPeer: function(),
  clearHistory: function(),
  exportChain: function(),
  getDatadir: function(callback),
  getNodeInfo: function(callback),
  getPeers: function(callback),
  importChain: function(),
  removePeer: function(),
  sleep: function github.com/ethereum/go-ethereum/console.(*bridge).Sleep-fm(),
  sleepBlocks: function github.com/ethereum/go-ethereum/console.(*bridge).SleepBlocks-fm(),
  startRPC: function(),
  startWS: function(),
  stopRPC: function(),
  stopWS: function()
}

如果单单想看nodeInfo的信息可以执行：

admin.nodeInfo.enode

运行结果：

"enode://29af54c8bbc87acf38f2b259966a1c54ef25d5293c8b447080cbd8bd18fb3fc06e692c43a7ea8011708f217776420cc48fb8ef5d5aa3bcf39528a52963b0a8f2@[::]:30303?discport=0"

这样就可以选择一部分信息进行展示

交易：
以太坊在交易的时候，必须先解锁账户，执行挖矿，并且生产新的区块，交易才能完成。
解锁账户
personal.unlockAccount(eth.accounts[0])

web3.eth.sendTransaction({from:web3.eth.accounts[0] , to:web3.eth.accounts[1],value: web3.toWei(1, "ether")})

挖到新的区块，则交易完成。
