#1. NCloud에 Centos7.8 64bit 서버생성

기존 PostgreSQL 9.6.X 에서 PostgreSQL 11.X 로 업그레이드를 꼭 해야 하는일이 생겨서 이제는 포스팅으로 이력을 남겨본다. 

1. 서버생성

2. 인증키 생성

3. 네트워크 접근 설정

4. 최종확인

5. 서버생성

6. ACG 규칙설정

7. Public IP 신청 및 할당

 

8. 스토리지 상태확인 및 추가

[root@flas ~]# fdisk -l

9. 디스크 파티션

[root@flas ~]# fdisk /dev/xvdb
Welcome to fdisk (util-linux 2.23.2).

Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.
