[이더리움개발101] Truffle, Ganache-cli 설치, Initial 배포

1. 이더리움 배포와 테스트를 위한 Truffle(배포), Ganach-cli(테스트) 설치

 

> npm install truffle -g
> npm install ganache-cli -g

 

2. 설치 후 version 확인

 

> truffle version
Truffle v5.5.7 (core: 5.5.7)
Ganache v^7.0.3
Solidity - 0.8.13 (solc-js)
Node v16.13.2
Web3.js v1.5.3

 

3. Truffle 초기화

 

> truffle init
> tree 
.
├── contracts
│   └── Migrations.sol
├── migrations
│   └── 1_initial_migration.js
├── test
└── truffle-config.js

 

4. Sample 계약서(Lottery.sol) 추가

 

contracts 디렉토리 안에 Lottery.sol 작성

 

// SPDX-License-Identifier: MIT
pragma solidity >=0.4.22 <0.9.0;

contract Lottery {
 
}

 

5. 배포를 위한 js 작성

 

truffle에서 배포는 migrations 디렉토리 안의 번호 순으로 배포된다. 즉, 1_initial_migration.js 다음에 Lottery 계약서를 배포할 2_deploy_smart_contract.js를 작성한다. deployer는 truffle-config.js 에 정의되어 있다.

 

const Lottery = artifacts.require('Lottery');

module.exports = function(deployer) {
    deployer.deploy(Lottery);
};

 

6. development 네트워크 환경 설정

 

로컬에서 배포가 이루어질 수 있도록 truffle-config.js를 수정한다. network 안의 아래 development 부분을 주석 해제한다.

 

    development: {
      host: "127.0.0.1",     // Localhost (default: none)
      port: 8545,            // Standard Ethereum port (default: none)
      network_id: "*",       // Any network (default: none)
    },

 

7. truffle 배포

 

'truffle migrate' 명령으로 계약서 compile과 배포가 이루어진다. 다시 truffle migrate 하면 이전에 배포된 것 이외에 추가된(즉, 3_xxxx으로 시작되는 js 파일) 부분만 배포되므로, 처음부터 다시 배포하고 싶으면 'truffle migrate --reset'을 입력한다.

8. 배포된 계약서 확인

 

ganache-cli로 제대로 배포되었는 지 접근해서 확인할 수 있다. ganche-cli 의 -d 옵션은 주어진 mnemonic (여기서는 tutorial)에 기반해서 주소를 만들라는 의미라고 한다. 아래와 같이 수행되면  정상적 배포 완료

 

> ganache-cli -d -m tutorial

Ganache CLI v6.12.2 (ganache-core: 2.13.2)
