[RaspberryPI] 설정 따라하기...

Raspberry PI 설정

• Raspbian Image Download : https://downloads.raspberrypi.org/raspbian_lite_latest
• 압축 해제 후 인스톨 가이드에 따라 SD카드 이미지에 복원
• Raspberry PI에 SD카드 삽입 후 모니터 연결 후 전원 연결 (키보드도 미리 연결)
  • SD카드에 맞게 자동으로 리사이즈 과정 진행 됨.
  • 리부팅 후 login 프롬프트가 뜨면 로그인 ( pi / raspberry )
  • sudo raspi-config 실행
  • TUI 에서 필요한 항목 셋팅 (언어, 타임존 등등)
• 필요한 소프트웨어 설치
  • docker 설치 - sudo apt install docker.io
  • python3 pip 설치 - sudo apt install python3-pip
  • docker-compose 설치 - sudo pip3 install docker-compose (4.7일 기준 1.25.4버전이 설치됨)
  • open jdk8 설치 - sudo apt install openjdk-8-jdk
• GPIO 커맨드툴 설치
  • wget https://project-downloads.drogon.net/wiringpi-latest.deb
  • sudo dpkg -i wiringpi-latest.deb
