BlockStore 접속시 Error: Axios Error (Request): Network Error (possible local connectivity issue) get~~ 발생 이유

 

## 해결방안

 

1. DB서버의 JWT 값을 찾아서 sudo /edx/etc/lms.yml 값과 /edx/etc/studio.yml 외 기타 *.yml 파일에 
   JWT 항목 동일하게 수정 (매번 다름 / 4칸,4칸 띄어쓰기 주의)

2. BlockStore .env 파일 수정후, 재빌드 수행
- 도메인 및 HTTPS 설정으로 URL 변경 필요  (하기 내용 수행)

 

-> BlockStore Frontend 설치
   - mkdir workspace  (우분투 홈폴더에서 실행)
   - cd workspace
   - git clone http://3.36.XXX.XXX:1114/fox0807/frontend-app-library-authoring
   - cd frontend-app-library-authoring
   - url 수정 : .env
     : vi .env  (LMS 및 기타 18000 포트 제거)
     : :%s/localhost/3.37.XXX.XXX/g   (localhost 를 IP로 일괄 변경)
     - LMS_BASE_URL='https://lms.koaXXX.ga'
     - STUDIO_BASE_URL='https://studio.koaXXX.ga'
     - LOGIN_URL='https://lms.koaXXX.ga/login'
     - LOGOUT_URL='https://lms.koaXXX.ga/logout'
     - MARKETING_SITE_BASE_URL='https://lms.koaXXX.ga'
     - REFRESH_ACCESS_TOKEN_ENDPOINT='https://lms.koaXXX.ga/login_refresh'

   - 컴파일 필수로 할것
   - sudo make requirements
   - sudo npm audit fix
   - sudo npm run build
   - sudo npm install forever -g

   - cd /home/ubuntu/workspace/frontend-app-library-authoring
     : $ sudo forever start server.js  (forever 실행)
     : $ sudo forever list  (정상여부 확인)
     : $ sudo forever stop 0  (forever 중지)

   - sudo vi /etc/nginx/sites-enabled/blockstore 수정
     : listen 80; ---> listen 18250; 변경

   - Nginx 및 EDX 서비스 재시작
     : sudo systemctl restart nginx
     : sudo /edx/bin/supervisorctl restart all

   - Blockstore 접속 테스트 (http://IP:3001/)  (성공)

   - 그래도 Error: Axios Error (Request): Network Error (possible local connectivity issue) get~~ 로그 발생하면
     : vi blockstore.yml 에서 DNS 수정해 볼것
       <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
       기타 URL도 가능시 변경해 볼 것
       SOCIAL_AUTH_EDX_OAUTH2_ISSUER: http://lms.koaXXX.ga
       SOCIAL_AUTH_EDX_OAUTH2_KEY: blockstore-sso-key
       SOCIAL_AUTH_EDX_OAUTH2_LOGOUT_URL: http://lms.koaXXX.ga/logout

       SOCIAL_AUTH_EDX_OAUTH2_URL_ROOT: http://lms.koaXXX.ga
