오라클 클라우드에 개인용 Redmine을 사용하고 있으며

어느날 갑자기 아래와 같은 오류가 발생하였고, 조치방법 입니다.

오류 상황에서 화면에는 딱 아래의 내용만 표시됩니다.

위 내용을 열심히 해석하고 포함된 링크들을 모두 클릭해서 살펴보아도 별로 도움은 되지 않습니다. 

빠르게 포기하시고 먼저 오류를 살펴 보아야 합니다.

✔️cat /var/log/apache2/error.log 명령을 실행하여 오류 파일 내용을 확인합니다.

맨 마지막 오류부터 위로 올라가시며서 살펴보셨을 때 Gemfile.lock 관련 내용이 있다면 아래 조치 사항을 참고해서 해결하실 수 있을 것입니다.

✔️Gemfile.lock 파일의 permissions 관련 오류 해결 방법 (순서대로 명령을 실행하시면 됩니다.)

    $ sudo rm -rf /usr/share/redmine/Gemfile.lock
    $ sudo touch /usr/share/redmine/Gemfile.lock
    $ sudo chown www-data:www-data /usr/share/redmine/Gemfile.lock
    $ sudo service apache2 restart

용접기가 없으니 합판으로 만들어 봐야겠습니다.
