1: No redirect - Make no further changes to the webserver configuration.
2: Redirect - Make all requests redirect to secure HTTPS access. Choose this for
new sites, or if you're confident your site works on HTTPS. You can undo this
change by editing your web server's configuration.

IMPORTANT NOTES:
- Congratulations! Your certificate and chain have been saved at:
/etc/letsencrypt/live/visithome.shop/fullchain.pem
Your key file has been saved at:
/etc/letsencrypt/live/visithome.shop/privkey.pem
Your cert will expire on 2020-01-25. To obtain a new or tweaked
version of this certificate in the future, simply run certbot again
with the "certonly" option. To non-interactively renew all of
your certificates, run "certbot renew"
- Your account credentials have been saved in your Certbot
configuration directory at /etc/letsencrypt. You should make a
secure backup of this folder now. This configuration directory will
also contain certificates and private keys obtained by Certbot so
making regular backups of this folder is ideal.

2. 미래에 인증서 갱신을 해주기 위해 "certonly" 옵션을 주고 다시한번 실행한다.
certbot certonly --nginx(앞으로 나오는 질문들에 대한 응답 모음 )

Cert not yet due for renewal
You have an existing certificate that has exactly the same domains or certificate name you requested and isn't close to expiry.
(ref: /etc/letsencrypt/renewal/visithome.shop.conf)
What would you like to do?

1: Keep the existing certificate for now

3. 자동갱신
유효 기간이 3개월이므로 3개월 마다 자동 갱신을 해주어야한다.
만료 날짜에 신경쓰기 싫을때는 매일 갱신하도록 /etc/crontab에 다음과 같이 추가한다.
(매일 0시 0분에 실행한다. 정확한 만료 날짜를 알면 정확하게 지정한다.)
vi /etc/crontab
0 0 * * * root certbot -q renew --nginx >> /var/log/letscript.renewal.log 2>&1 #추가
service cron restart
4. 설정파일 자동수정
설치된 인증서는 /etc/letsencrypt/live/lilyspace.shop에서 확인할 수 있다.
실행 결과 nginx의 환경파일(/etc/nginx/sites-available/defaut)이 자동 수정된다.
vi /etc/nginx/sites-available/default
(vi /etc/nginx/sites-enabled/default vs vi /etc/nginx/sites-available/default 차이
차이는 잘모르겠지만 주로 available을 쓴다. )
5. https 적용 확인
