IMPORTANT NOTES:

- Congratulations! Your certificate and chain have been saved at:

/etc/letsencrypt/live/wechat.yuanfusc.com/fullchain.pem //证书和链路径

Your key file has been saved at:

/etc/letsencrypt/live/wechat.yuanfusc.com/privkey.pem //密钥文件路径

Your cert will expire on 2019-03-24. To obtain a new or tweaked

version of this certificate in the future, simply run certbot

again. 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.
