리눅스 rails 설치

rails 설치

레일즈 설치

루비 온 레일즈 설치

1 사전 작업

• RVM ruby 설치

2 사용자 계정 생성

• root 계정으로 rails를 설치하다 보면 "Don't run Bundler as root."라는 메시지가 나온다.
• 권장사항대로 별도의 계정을 만들어 진행한다.
• 여기서는 간단히 railsuser라는 계정을 만들었는데, 다른 계정명을 써도 된다.

root@zetawiki:~# useradd railsuser -m -G rvm -s /bin/bash
root@zetawiki:~# cat /etc/passwd | grep railsuser
railsuser:x:1000:1001::/home/railsuser:/bin/bash

root@zetawiki:~# cat /etc/group | grep railsuser
rvm:x:1000:railsuser
railsuser:x:1001:

root@zetawiki:~# su - railsuser
railsuser@zetawiki:~$ pwd
/home/railsuser
