openstack 구축 4 placement

---

• placement는 openstack에서 사용되는 리소스를 할당하고 배치하는데 사용되는 서비스다
• keystone 보다는 설정할게 많지만 다른 서비스들보다 설정할게 적으니 잘 따라오면 오타없이 성공적으로 설치할 수 있을 것이다.
• 원래 공식 메뉴얼에서 보안PW를 설정할때 PLACEMENT_PASS와 PLACEMENT_DBPASS를 따로두지만 실제로 따로 설정했더니 keystone 연결시 인증서에 문제가 생겨서 PLACEMENT_PASS로 통일시켜 같은 PW를 사용했다.
