Installing SSL in a Site in Sentora / Cent OS

In Console

yum install certbot python2-certbot-apache mod_ssl openssl

(If it shows any error, then yum install epel-release and run above command again)

THIS WAS NOT REQUIRED WHEN I WORKED ON CSMCL.IN. So this step can be dropped.
Comment listen 443 to #listen 443 in /etc/httpd/conf.d/ssl.conf using NANO
(Still to figure out if above line is mandatory or not. Will check when installing it in third server)

THERE ARE 2 DASHES BEFORE APACHE BELOW.

certbot –apache for enabling ssl in all sites on the server

certbot –apache –d domain1 –d domain 2 for enabling ssl on selected domains
if it fails, use certbot -d domain1 -d domain2 (using -apache causes issue in some systems)

Rest is fully automatic

Later Check certs

certbot certificates

One click renew all expiring certs

certbot renew

/// In case you have to delete a cert

certbot revoke --cert-path /etc/letsencrypt/live/CERTNAME/cert.pem

certbot delete --cert-name example.com
