Let's Encrypt 인증서 발급

도메인입력

a.domain.com, b.domain.com, c.domain.com

IP being logged? 동의

인증관련 폴더 선택하는 부분이 나오는데 아래쪽에 설정한

/home/data/letsencrypt 폴더 선택 하면 알아서 인증해줌.

vi ssl_domain.conf

listen          443 ssl;

ssl on;

ssl_certificate         /etc/letsencrypt/live/a.domain.com/fullchain.pem;

ssl_certificate_key     /etc/letsencrypt/live/a.domain.com/privkey.pem;

위와 비슷하게 설정하면 됨.

nginx 에서 ssl 적용할 도메인 설정된 부분

letsencrypt 는 3개월에 한번씩 갱신해줘야함.
