大螃嗨

系统环境： CentOS 7.4 64bit

搭建geth环境 #去官网下载符合自己服务器的geth客户端https://ethereum.github.io/go-ethereum/downloads/

wget https://gethstore.blob.core.windows.net/builds/geth-linux-amd64-1.7.3-4bb3c89d.tar.gz
tar -vxzf geth-linux-amd64-1.7.3-4bb3c89d.tar.gz
mv geth-linux-amd64-1.7.3-4bb3c89d/geth /usr/local/bin/
geth --datadir testNet --dev console

安装Node.js 从官网获取最新的代码https://nodejs.org/en/download/

wget https://nodejs.org/dist/v8.9.4/node-v8.9.4-linux-x64.tar.xz
tar --strip-components 1 -xvf node-v8.9.4-linux-x64.tar.xz -C /usr/local
node --version

安装truffle

yum install npm
npm install -g truffle

创建项目

truffle unbox tutorialtoken
npm install zeppelin-solidity

进入contracts目录创建名为TutorialToken.sol的合约

vi TutorialToken.sol

代码如下：

pragma solidity ^0.4.2;

import 'zeppelin-solidity/contracts/token/StandardToken.sol';

contract TutorialToken is StandardToken{
string public name = 'PangxieToken';
string public symbol = 'PangxieToken';
uint8 public decimals = 2;
uint public INITIAL_SUPPLY = 12000;
function TutorialToken() public{
totalSupply = INITIAL_SUPPLY;
balances[msg.sender] = INITIAL_SUPPLY;
}
}

在migrations目录下建立2_deploy_contracts.js

var TutorialToken = artifacts.require("TutorialToken");
module.exports = function(deployer) {
deployer.deploy(TutorialToken);
}

编译合约

truffle compile

部署合约前需要新开一个终端开启测试网络

testrpc
truffle migrate
npm dev run
