Certbot doesn't know how to automatically configure the web server on this system. However, it can still get a certificate for you. Please run "letsencrypt-auto certonly" to do so. You'll need to manually configure your web server to use the resulting certificate.

apache 를 패키지로 설치 하지 않고, 컴파일 하여 설치 한 경우라 그런지 PATH 에서 apache2ctl 명령을 찾을 수 없다고 한다.

IMPORTANT NOTES:
- Congratulations! Your certificate and chain have been saved at
/etc/letsencrypt/live/freecatz.pe.kr/fullchain.pem. Your cert will
expire on 2017-07-04. To obtain a new or tweaked version of this
certificate in the future, simply run letsencrypt-auto again. To
non-interactively renew *all* of your certificates, run
"letsencrypt-auto 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.
