IT개발 정보 정리

[주의사항]

* 도커는 기본적으로 root 권한이 필요합니다. 사용자 계정으로 sudo 없이 사용하려면 해당 사용자를 docker 그룹에 추가해야 합니다.

* 설치도중 또는 설치 후 fabric 샘플 소스를 실행할 때 root 권한이 맞는지 잘 확인해주세요.

* 특정 사용자 계정으로 진행할 경우 아래 모든 명령어들은 사용자 계정 및 root 계정 모두 지정된 버전으로 실행되어야 합니다.

[특정 사용자를 docker 그룹에 추가 (추천)]

sudo usermod -aG docker 사용자계정

[CentOS 7 - 환경 구축]

[도커 이미지 다운로드]

# HyperLedger Fabric 도커 이미지 및 바이너리 다운로드 cd ~ mkdir -p go/src/github.com/hyperledger cd go/src/github.com/hyperledger sudo curl -sSL https://goo.gl/6wtTN5 | sudo bash -s 1.1.0 (* docker 그룹에 사용자계정을 추가했을 경우 sudo 를 안써도 된다.) curl -sSL https://goo.gl/6wtTN5 | bash -s 1.1.0

* 도커 필수 이미지를 받는 스크립트의 경우 사용자 계정을 docker 그룹에 추가하지 않으면

  sudo 를 통해 실행해야 docker 명령어가 정상적으로 수행됩니다. 그러나 sudo 를 사용하면 다운받는 fabric-samples 폴더 소유자가 root 가 되어

  소유 및 권한을 다시 사용자계정으로 변경해 주거나 이후 샘플 폴더 안에서 실행할 작업들을 모두 sudo 로 진행해야 합니다.

* 사용자 계정을 docker 그룹에 추가 (sudo usermod -aG docker 사용자계정) 한 후 위 스크립트를 진행한다면 sudo 명령어를 빼고 실행해도 되며

  (curl -sSL https://goo.gl/6wtTN5 | bash -s 1.1.0) 이럴 경우 fabric-sample 폴더는 사용자계정 소유로 진행되고 추후 작업들도 sudo 없이 진행 가능합니다.

[환경변수 설정]

# go 환경변수 sudo vi /etc/profile # 프로필 맨 아래 추가 # GOPATH 는 golang 의 workspace 와 비슷하므로 원하는 곳으로 설정해도 괜찮습니다. export GOPATH=/home/사용자계정/go export PATH=/usr/local/go/bin:$PATH # 나중에 소스코드 실행 시 또는 Chaincode 수정시 peer, configtxgen, cryptogen 등 관련 명령어를 못찾는 오류가 생길 경우 export PATH=$HOME/go/src/github.com/hyperledger/fabric-samples/bin:$PATH source /etc/profile
