안녕하세요. IT반장입니다.

Hyperledger 두번째 시간인 환경 구성에 대해 알아보겠습니다.

2. Hyperledger 환경 구성

ㅇ Hyperledger를 설치하고, 체인코드를 개발하기 위한 환경 설정을 살펴봅니다.

 ※ OSX 또는 리눅스 운영체제를 추천합니다. 현재 Windows는 GO언어의 파일 권한 설정 버그가 있습니다.

ㅇ 테스트 환경

 - 하드웨어: PC급(미니 PC급 사양, 64비트 지원)

 - OS: 리눅스(Ubuntu Desktop 16.04 LTS 64비트)

※ 원활한 환경을 구성을 위해서는 64비트를 설치해야 합니다.  docker, crome 등이 64비트만 지원됩니다.

 

---

가. 리눅스 설치하기

 - 생략(향후 작성 또는 링크)

$ sudo apt-get update $ sudo apt-get -y upgrade $ sudo apt-get install git python-pip

다. GO 언어 설치 및 환경 설정

$ sudo add-apt-repository ppa:longsleep/golang-backports $ sudo apt-get update $ sudo apt-get install golang-go ; go 언어 1.8 버전을 설치하는 방법이다. $ sudo vi /etc/profile ;  "export GOPATH=$PWD/go"를 추가한다. $ source /etc/profile $ env | grep GOPATH

라. node.js 및 npm 설치
