Ruby를 설치하기전 rvm을 사전 설치해야한다.

1. 개요

1-1.우분투 ruby-rvm 설치하기

1-2.우분투 RVM 설치

과정 수행 완료시 rvm, ruby, gem 설치 완료

2. rvm 설치 확인

GitHub - rvm/ubuntu_rvm: Ubuntu package for RVM

Ubuntu package for RVM. Contribute to rvm/ubuntu_rvm development by creating an account on GitHub.

github.com

먼저 우분투에서 rvm을 설치해야한다. 위 사이트에서 우분투 용 rvm을 설치한다.

sudo apt-add-repository -y ppa:rael-gc/rvm
sudo apt-get update
sudo apt-get install rvm

설치완료후 rvm 버전확인후 버전이 뜨면 설치완료

kim@kim-ThinkPad-X1-Carbon-Gen-8:~$ rvm version

8. 루비 설치 (현재 최신 버전 3.1.1)

kim@kim-ThinkPad-X1-Carbon-Gen-8:~$ rbenv install --verbose 3.1.1

설치하는데 조금 걸린다. 여유롭게 기다려준다.

9.루비 설정 및 확인

 rbenv global 3.1.1

10. 리눅스 rails 설치전 사용자 계정 생성

먼저 root 계정으로 rails를 설치하다 보면 "Dont't run Bundler as root."라는 메시지가 나온다.
권장 사항대로 별도 계정을 만들어 진행한다.
여기서 간단히 railsuser라는 계정을 만들었는데, 다른 계정을 써도된다.

kim@kim-ThinkPad-X1-Carbon-Gen-8:~$ useradd kim -m -s /bin/bash
useradd: 'kim' 사용자가 이미 있습니다
kim@kim-ThinkPad-X1-Carbon-Gen-8:~$ ech 'kim:P@ssOrd' | chpasswd

명령어 'ech' 을(를) 찾을 수 없습니다. 다음 명령어로 시도하시겠습니까:

  deb ecpecere-dev의 명령어 ' (0.44.15-1build3)'
  deb ecsecere-dev의 명령어 ' (0.44.15-1build3)'
  deb bchbikeshed의 명령어 ' (1.78-0ubuntu1)'
  deb schscheme2c의 명령어 ' (2012.10.14-1ubuntu1)'
  deb ecjecj의 명령어 ' (3.16.0-1)'
  deb eclecl의 명령어 ' (16.1.3+ds-4)'
  deb dchdevscripts의 명령어 ' (2.20.2ubuntu2)'
  deb echocoreutils의 명령어 ' (8.30-3ubuntu2)'
  deb ecmgmp-ecm의 명령어 ' (7.0.4+ds-5)'
  deb eccecere-dev의 명령어 ' (0.44.15-1build3)'

Try: sudo apt install <deb name>

kim@kim-ThinkPad-X1-Carbon-Gen-8:~$ echo 'kim:P@ssOrd' | chpasswd
kim에 대한 암호 변경 중
chpasswd: (user kim) pam_chauthtok() failed, error:
