주의! - 'bundle update' 후에 'bundle install'을 실행해야 함
rails server 실행
- 웹서버를 실행하기 전에 로컬 웹서버 접속을 허용한다.
- 작업경로는 '~/environment/hello_app/'
로컬서버 연결 허용을 위한 설정파일: config/environments/development.rb
...
# Use an evented file watcher to asynchronously detect changes in source code,
# routes, locales, etc. This feature depends on the listen gem.

rails:~/environment/hello_app (master) $ rails server
=> Booting Puma
=> Rails 6.0.2.1 application starting in development
=> Run `rails server --help` for more startup options
Puma starting in single mode...
* Version 3.12.2 (ruby 2.6.3-p62), codename: Llamas in Pajamas
* Min threads: 5, max threads: 5
* Environment: development
* Listening on tcp://localhost:8080
Use Ctrl-C to stop
접속주소는 http:/localhost:3000
AWS Cloud9 을 사용하는 경우, 로컬 컴퓨터 브라우저로 접속을 시도하면...
"~~ 연결을 거부했습니다."는 메시지가 나오는 경우가 있다.
이 경우에는 위의 그림의 적색 동그라미 부분을 클릭해서 접속하면 된다.
[요약: Cloud9 IDE사용하여 Ruby on Rails 셋업방법]
------------------------------------------------------
주의! 설치전에 ruby 버전 EOL 정보 반드시 확인할 것
- 2021.5.1일 현재 안정 릴리스: ruby 2.7.3 또는 3.0.1
- 보안 유지보수 단계: 루비 2.6.7(곧 EOL 예정!)
rails 5.2.5 또는 최신버전 6.1.3.1
------------------------------------------------------
*시작 전 루비버전 확인: ruby -v
단계1. 레일즈 설치
$ echo "gem: --no-document" >> ~/.gemrc # 도움말 파일 제외
$ gem install rails -v 6.1.3.1 # 설치 명령
$ rails -v # 설치된 버전확인
단계2. yarn 설치 (yarn은 npm같은 js 패키지 관리자. 빠르고 안정적)
$ source <(curl -sL https://cdn.learnenough.com/yarn_install)
$ yarn install --check-files
단계3. hello_app 생성
$ cd ~/environment
$ rails _6.1.3.1_ new hello_app
단계4. bundle 설치
$ cd hello_app/
$ bundle update
$ bundle install
단계5. 웹서버 실행
필수! - 클라우드 환경에서 로컬 웹서버 접근가능하도록 설정
# hello_app/config/environments/development.rb 파일에 아래 1줄 추가
...
config.hosts.clear ##
end
IDE에서 별도 터미널 탭 사용하여 웹서버 실행
$ cd ~/enviroment/hello_app
$ rails server
환경설정 끝.
