Cerbot 갱신 에러
Certbot 으로 SSL 을 갱신하려는데 이전과 같은 방법으로 명령을 실행하자 실패를 반복하는 문제가 생겼다. 전에는 분명히 같은 방법으로 갱신을 했는데…? 하고 찾아보니 비슷한 현상이 꽤 있는지, 여러 사람들이 포럼에서 질문과 답변을 하고 있었다.
증상
실행한 명령은 다음과 같다.
$ sudo certbot renew --dry-run
[sudo] password for someuser:

IMPORTANT NOTES:
- The following errors were reported by the server:
Domain: some.domain.com
Type: unauthorized
Detail: Invalid response from
https://some.domain.com/.well-known/acme-challenge/7777777777777777777777777777777777_77777777

To fix these errors, please make sure that your domain name was
entered correctly and the DNS A/AAAA record(s) for that domain
contain(s) the right IP address.
결과에 IPv6 가 보여 DNS 레코드에 AAAA 가 설정이 되어 있으면 IPv6 를 선호한다는 이야기가 있어 DNS 및 서버 설정을 확인했지만 문제는 없었다.
결국, 웹서버로 사용하는 Nginx 의 설정 파일을 Certbot 이 잘 가져오지 못하여 webroot 를 확인하지 못하는 것 같은 느낌이 들어 webroot 를 지정하여 명령을 실행하자 갱신이 잘 된다.
$ sudo certbot renew -a webroot -w /somepath/some.domain.com/public_path --dry-run

해결방법
webroot 를 수동으로 지정한다.
# Error: sudo certbot renew --dry-run
$ sudo certbot renew -a webroot -w /somepath/some.domain.com/public_path --dry-run
