SSL & Let’s encrypt on ddns acount
port forward on your router to your local ip computer where you run node-red: refer to your router user manual
install light web server if you don’t have one installed (need only to setup let’encrypt cert) NB: you can use also ngix proxy solution see below)
sudo apt-get install lighttpd
sudo lighttpd-enable-mod userdir
sudo service lighttpd reload
certboot install:
sudo apt-get install letsencrypt
var/www/html/ with the proper dir of your installed server and yoursite.ddns.net with your site
sudo letsencrypt certonly --webroot -w /var/www/html/ -d yoursite.ddns.net
result must be somethin like this:
admin@yourcomputer ~ $ sudo letsencrypt certonly --webroot -w /var/www/html/ -d yoursite.ddns.net
IMPORTANT NOTES:
- Congratulations! Your certificate and chain have been saved at
/etc/letsencrypt/live/yoursite.ddns.net/fullchain.pem.
Your cert will expire on 2017-05-06. To obtain a new version of the
certificate in the future, simply run Let's Encrypt again.
