How to Renew the SSL certs​

  • SSH into the ec2 instance 
$ ssh -i main.cer ec2-user@ec2-18-216-84-227.us-east-2.compute.amazonaws.com
  • turn off httpd and nginx with these commands: 
$ service httpd stop
$ service nginx stop
  • Run certbot renew, make sure httpd and nginx or turned off.
$ certbot renew --force-renewal

^ this command simply checks to see that the certificates are renewed

To renew a certificate, you have to run this command: 

$ certbot certonly --standalone --preferred-challenges http
$ certbot certonly --standalone --preferred-challenges dns
$ certbot certonly --standalone --preferred-challenges tls-alpn-01

These commands change a lot as the letsencrypt people are always chaning the challenges.

if everything works out, then turn back nginx and httpd: 

$ service httpd start
$ service nginx start
