P75 、1-以太坊私网建立 、合约编译、部署完全教程（1）

使用此博文进行安装配置：https://blog.csdn.net/w88193363/article/details/79402074

一、搭建私有链所需的依赖环境

操作系统：ubuntu16.04，开虚拟机的话要至少2G，否则会影响测试挖矿时的速度

软件：geth客户端 版本：1.8.1-stable-1e67410e

二、安装geth客户端

【Ctrl+Alt+T】打开终端，依次输入以下命令：

代码语言：javascript
复制
sudo apt-get update

sudo apt-get install software-properties-common

sudo add-apt-repository -y ppa:ethereum/ethereum

sudo add-apt-repository -y ppa:ethereum/ethereum-dev

sudo apt-get update


sudo apt-get install ethereum

安装完成后，输入geth -h，如果有列出信息则说明安装成功，可查看列出信息，方便后续的操作

三、建立私链：

1、创建一个文件夹来存储你的私链数据

代码语言：javascript
复制
mkdir privatechain
cd privatechain

2、使用geth来加载

代码语言：javascript
复制
geth --networkid 123 --dev --datadir data --rpc --rpcaddr 192.168.2.223 --rpcport 8545 --port 3000 console

各选项含义如下：

  • --identity：指定节点 ID；
  • --rpc：表示开启 HTTP-RPC 服务；
  • --rpcaddr：HTTP-RPC 服务ip地址；
  • --rpcport：指定 HTTP-RPC 服务监听端口号（默认为 8545）；
  • --datadir：指定区块链数据的存储位置；
  • --port：指定和其他节点连接所用的端口号（默认为 30303）；
  • --nodiscover：关闭节点发现机制，防止加入有同样初始配置的陌生节点。

执行上面的命令，你应该能看到下面的信息：

INFO [10-15

03:14:50] IPC endpoint opened: /Users/liyuechun/Desktop/1015/privchain/geth.ipc

INFO [10-15

03:14:50] HTTP endpoint opened: http://127.0.0.1:8545

为了方便操作，我们将上面的命令存为init.sh：

代码语言：javascript
复制
nano init.sh

//输入
geth --networkid 123 --dev --datadir data --rpc --rpcaddr 192.168.31.140 --rpcport 8545 --port 3000 console

//赋予执行权限
chmod 775 init.sh

保持节点的运行，不要关闭终端，重新打开一个终端，使用geth attach连接节点，并且打开geth console

代码语言：javascript
复制
geth attach ipc:data/geth.ipc

 为了方便操作，我们将上面的命令存为connect.sh：

代码语言：javascript
复制
nano connect.sh

//输入
geth attach ipc:data/geth.ipc

//赋予执行权限
chmod 775 connect.sh

这是一个交互式的 JavaScript 执行环境，在这里面可以执行 JavaScript 代码，其中 > 是命令提示符。在这个环境里也内置了一些用来操作以太坊的 JavaScript 对象，可以直接使用这些对象。这些对象主要包括：

  • eth：包含一些跟操作区块链相关的方法；
  • net：包含一些查看p2p网络状态的方法；
  • admin：包含一些与管理节点相关的方法；
  • miner：包含启动&停止挖矿的一些方法；
  • personal：主要包含一些管理账户的方法；
  • txpool：包含一些查看交易内存池的方法；
  • web3：包含了以上对象，还包含一些单位换算的方法。

另外开启一个终端1

代码语言：javascript
复制
cd privatechain/data
geth attach ipc:geth.ipc

3、相关api命令

查看账户

代码语言：javascript
复制
personal.listAccounts

创建账户

代码语言：javascript
复制
personal.newAccount("密码")

4、web3命令 

查看创世账户

代码语言：javascript
复制
web3.eth.coinbase

获取账户

代码语言：javascript
复制
personal.listAccounts[1]

查看账户余额

代码语言：javascript
复制
eth.getBalance("账户地址")
//eth.getBalance(personal.listAccounts[0])

开始挖矿

代码语言：javascript
复制
miner.start();

停止挖矿

代码语言：javascript
复制
miner.stop();

终端1账户0向账户1转账

代码语言：javascript
复制
//解锁账户0(密码为空)
personal.unlockAccount(personal.listAccounts[0]);
//以太币转wei
amount = web3.toWei(5,'ether');
//转账
eth.sendTransaction({from:personal.listAccounts[0],to:personal.listAccounts[1],value:amount});
//查看交易状态
txpool.status
//查看区块信息
eth.getBlock("pending",true);
//开始挖矿
miner.start();
//停止挖矿
miner.stop();
//查看交易状态
txpool.status
//查看账户1的余额
eth.getBalance(personal.listAccounts[1])
//转账成功！！！
//查看区块数
eth.blockNumber
//查看交易信息
eth.getTransaction("0xc9d079c276cb8d026705430d1f0c543d88d11e6058f09b17717c7dc7df222dcd")
//查看区块信息（区块号）
eth.getBlock(1)

5、mist钱包连接私链

Mist钱包下载地址：https://github.com/ethereum/mist/releases

Mist = Ethereum Wallet + Web3 浏览器

下载：Mist-linux64-0-11-1.zip

解压

代码语言：javascript
复制
unzip Mist-linux64-0-11-1.zip /home/ethereum/Mist

使用mist链接到私链

代码语言：javascript
复制
"/home/ethereum/Mist/mist" --rpc "/home/ethereum/privatechain/init/data/geth.ipc"

 为了方便操作，我们将上面的命令存为mist.sh：

代码语言：javascript
复制
nano mist.sh

//输入
"/home/ethereum/Mist/mist" --rpc "/home/ethereum/privatechain/init/data/geth.ipc"

//赋予执行权限
chmod 775 mist.sh

打开即可

代码语言：javascript
复制
./mist.sh

6、编写智能合约 

这里我们部署合约分两种情况：

  • 命令行方式部署
  • Mist钱包中部署

a、命令行方式部署

终端1编写合约

代码语言：javascript
复制
cd privatechain
nano DemeterContract.sol

输入以下内容，并保存：

代码语言：javascript
复制
pragma solidity ^0.5.4;

contract DemeterContract {
    mapping (address => uint) balances;
    event Transfer(address indexed _from, address indexed _to, uint256 _value);

    uint public ticketIndex;
    mapping(address => mapping(uint => Ticket)) stores;
    mapping(uint => address) ticketIdInStore;

    struct Ticket{
        uint id;   //票据id
        string name;  //票据名称

        string content;  //票据内容
        address receiveraddr;  //付款人地址
        //address payeeaddr;   //收款人地址
    }

    constructor() public{
        ticketIndex = 0;
        balances[tx.origin] = 10000;
    }

    function sendCoin(address receiver, uint amount) public returns(bool sufficient) {
        if (balances[msg.sender] < amount) return false;
        balances[msg.sender] -= amount;
        balances[receiver] += amount;
        emit Transfer(msg.sender, receiver, amount);
        return true;
    }

    function getBalanceInEth(address addr) public view returns(uint){
        return getBalance(addr);
    }

    function getBalance(address addr) public view returns(uint) {
        return balances[addr];
    }

    /*  添加票据信息到区块链  */
    function addTicketToStore(string memory _name,string memory _content, address _receiveraddr) public {
        ticketIndex += 1;
        Ticket memory ticket = Ticket(ticketIndex, _name, _content, _receiveraddr);
        stores[msg.sender][ticketIndex] = ticket;
        ticketIdInStore[ticketIndex] = msg.sender;
    }

    /*  添加票据信息到区块链  */
    function addTicketToStoreByAddress(string memory _name,string memory _content, address _senderaddr, address _receiveraddr) public {
        ticketIndex += 1;
        Ticket memory ticket = Ticket(ticketIndex, _name, _content, _receiveraddr);
        stores[_senderaddr][ticketIndex] = ticket;
        ticketIdInStore[ticketIndex] = _senderaddr;
    }

    /*  test  */
    function test(string memory _name, string memory _content, address _receiveraddr) public returns(uint,address,string memory,string memory) {
        ticketIndex += 1;
        Ticket memory ticket = Ticket(ticketIndex, _name, _content, _receiveraddr);
        stores[msg.sender][ticketIndex] = ticket;
        ticketIdInStore[ticketIndex] = msg.sender;

        /**/
        Ticket memory ticketback = stores[ticketIdInStore[ticketIndex]][ticketIndex];

        return (ticketIndex,msg.sender,ticketback.name,ticketback.content);
    }

    /*  通过票据id读取票据  */
    function getTicket(uint _ticketId) public view returns(uint, string memory, string memory){
        Ticket memory ticket = stores[ticketIdInStore[_ticketId]][_ticketId];
        return (ticket.id, ticket.name, ticket.content);
    }

    /*  通过票据id读取票据  */
    function getTicketByByAddress(address searcher, uint _ticketId) public view returns(uint, string memory, string memory){
        Ticket memory ticket = stores[ticketIdInStore[_ticketId]][_ticketId];
        //ticketIdInStore[_ticketId]==searcher
        if( ticketIdInStore[_ticketId] == searcher || ticket.receiveraddr == searcher )
            return (ticket.id, ticket.name, ticket.content);
        else
            return (0, "0", "0");
    }
}

安装solc

参考：https://blog.csdn.net/u013137970/article/details/52255001、https://www.cnblogs.com/lidonghao/p/8497145.html

代码语言：javascript
复制
npm install -g solc
//npm install -g solc-cli
//检测是否安装成功
solcjs --help

终端2获取字节码

代码语言：javascript
复制
//使用solcjs获取合约的字节码
solcjs --bin DemeterContract.sol
//使用gedit打开 ,并复制字节码
gedit DemeterContract_sol_DemeterContract.bin

终端1定义字节码变量（在字节码前面加上 0x）:

代码语言：javascript
复制

b、Mist钱包中部署

 花费1个eth

 将合约复制粘贴过来，并把合约版本改为 0.4.24（我们下载的mist钱包合约编译器的版本就是0.4.24）

 开始部署

 等待合约挖矿确认

P76 、2-以太坊私网建立 (2) - 同一台电脑／不同电脑运行多个节点

先思考两个问题

  • 决定存储区块链数据的目录
  • 选择网络id，默认1为主网

为了在同一台机器能够运行两个节点，我们需要为不同的节点设置不同的 port 和 rpcport。

复制
//去除--dev
geth --networkid 123 --datadir data2 --rpc --rpcaddr 192.168.1.23 --rpcport 9000 --port 3001 console

再新开启一个终端，执行
