    Let's Encrypt

1.SSH as root into the server

ssh root@SERVER_IP_ADDRESS

2.Install Certbot (ถ้าเคย install แล้วข้ามขั้นนี้)

$ sudo apt-get update
$ sudo apt-get install software-properties-common
$ sudo add-apt-repository ppa:certbot/certbot
$ sudo apt-get update
$ sudo apt-get install python-certbot-nginx

chmod a+x certbot-auto
mv certbot-auto /usr/bin/certbot

3.Stop NGINX

service nginx-sp stop

4.Run the certbot-auto Script

อันเก่าไม่ใช้แล้ว ใช้อันล่างแทน
certbot certonly --standalone -d DOMAIN_NAME.com -d www.DOMAIN_NAME.com

ใช้อันนี้แทน
certbot certonly --webroot -w /srv/users/serverpilot/apps/APP_NAME/public -d www.DOMAIN_NAME.com -d DOMAIN_NAME.com -d sub.domain.com -d sub2.domain.com

(ใช้โค๊ดนี้แทนที่ fork มา เพราะ cloudflare ทำให้ auto renew ไม่ได้)

The first time you run this command the process will take a few minutes, after it's finished installing, follow on screen instructions and you should get a message similar to:

Congratulations! Your certificate and chain have been saved at /etc/letsencrypt/live/DOMAIN_NAME.com/fullchain.pem.

5.Add SSL config file

nano /etc/nginx-sp/vhosts.d/APP_NAME.ssl.conf

APP_NAME = ServerPilot App Name (eg serverpilot/apps/myapp)
DOMAIN_NAME = Domain name (eg myawesomesite.com)

NOTE: The filename should match the serverpilot app name. Another way to know is to see what ever letsencrypt named what the files here /etc/nginx-sp/vhosts.d/APP_NAME.conf

6.Start NGINX

service nginx-sp start

Auto Renewing

7.Add crontab (ถ้าเคยทำแล้วข้ามขั้นนี้)

crontab -e

# letsencrypt-auto renew command every Monday at 2:30 am
30 2 * * 1 certbot renew --pre-hook "service nginx-sp stop" --post-hook "service nginx-sp start" >> /var/log/letsencrypt-renew.log

8.Checking if a cert needs to be renewed

certbot renew

9.Adding a new subdomain to certs (ถ้าไม่ add เพิ่มข้ามขั้นนี้)

certbot certonly --webroot -w /srv/users/serverpilot/apps/APP_NAME/public -d www.DOMAIN_NAME.com -d DOMAIN_NAME.com -d sub.domain.com -d sub2.domain.com

(ใช้โค๊ดนี้แทนที่ fork มา เพราะ cloudflare ทำให้ auto renew ไม่ได้)
ref: https://certbot.eff.org/docs/using.html#webroot
ETC.

ถ้าเจอ Problem binding to port 80: Could not bind to IPv4 or IPv6.

ลองรัน
fuser 80/tcp

ถ้ารัน service nginx-sp start แล้วเจอ

Job for nginx-sp.service failed because the control process exited with error code. See "systemctl status nginx-sp.service" and "journalctl -xe" for details.
