ceph - 기본설치2 - ceph 설치및 구성 (Ver. 10.2.11_jewel )
* ceph는 기본적으로 데비안계열 기반으로 진행 되는데, 본 포스팅은 centos에서 진행합니다.
* 해당 작업서버는 총 7대로써 컨트롤서버인 MGMT(mon 3rd,mds도 같이 사용예정) 1대, 모니터 서버 mon 2대, 스토리지 osd 4대로 구성합니다.
vm으로 테스트해도 동일하며, 다른 부분은 스토리지의 RAID를 하느냐, 단일 디스크들을 사용하는냐 입니다.
* ceph - 기본설치 2 는 MGMT(컨트롤서버) 서버에서만 진행합니다.

[ CEPH 설치 - MON 서버 구성 ] * 모든 작업은 mgmt 서버에서 진행 됩니다. * ceph-deploy 는 ceph설치 및 운영시 사용되는 관리 패키지 입니다. ceph-deploy를 통해 설정 변경 시 일괄적으로 배포하고, osd추가 등을 편리하게 작업하게 해줍니다. * yum update 해주세요. ceph-deploy 설치시 낮은 버젼으로 설치 되면 ceph 사이트 못찾아서 install 부터 장애가 발생됩니다.
