GitLab에 대한 액세스 확인

GitLab 로그인 화면이 열렸습니다. 비밀번호를 변경하라는 메시지가 표시되므로 비밀번호를 설정합니다.

암호를 설정한 후 Username/Password를 입력하여 로그인합니다.
　　- Username: root
　　- Password: [2단계에서 설정한 값]

GitLab에 성공적으로 로그인할 수 있었습니다.

비망록 : GitLab에 필요한 포트가 사용되고 할당되지 않은 경우

# vi /etc/gitlab/gitlab.rb
...
redis['port'] = 16379
postgresql['port'] = 15432
unicorn['port'] = 18080
...

# gitlab-ctl reconfigure
