인증서 자동갱신 되는 평생 무료 블로그 운영하기 (1) ✍️
1. Oracle Cloud 가입 및 VM 생성
컴퓨트 인스턴스를 항상 무료 적격 중에서 선택합니다.
접속 하려는 PC에 있는 SSH 키 파일을 선택해서 업로드 하거나 SSH 키 붙여넣으세요. (키 복사: pbcopy < ~/.ssh/id_rsa.pub 파일이 없다면 ssh-keygen 으로 생성)
인스턴스는 2대까지 평생 무료인데 생성하기가 쉽지는 않네요. 인내심을 가지고 자주 시도해 보세요 ㅠㅠ
보유중인 도메인이 있다면 정보를 업데이트 해줍니다. (Cafe24 예시)
접속을 확인해 봅니다.
