Virtual Box 세팅시.

redhat linux 64

16GB 이상의 RAM

150GB 수준의 스토리지 (동적할당)

프로세서 4개~8개 (네스티드 VT-x /AMD-V 사용하기 체크 : CPU 가상화)

NAT네트워크 1 + 호스트 전용 1

NIC 네트워크 무작위 설정 체크

 

 

설치시.

네트워크 -> General -> automatically connect … 체크

네트워크 -> IPv4 Settings -> 아이피설정 (호스트전용아이피는 Gateway 를 공란으로 저장)

네트워크 -> host name : allinone.osp.exam.com

INSTALLATION DESTINATION : 오토파티셔닝 해제 -> 확인 -> 홈디렉터리 할당 삭제(-) 클릭 -> 루트디렉터리(/) 전체할당 → update setting 클릭

  → TEST환경이므로 루트디렉터리에 할당.

  → 실제 환경에서는 각 디렉터리마다 권장사양에 맞춰 파티셔닝 진행

Server with Gui

Software selection : Server with GUI
