Very helpful article, just a few things to mention:
in Step 2:
systemctl restart httpd
apachectl -M | grep ssl
ssl_module (shared)
in RHEL8 (and Oracle Linux 8 if you’re counting) apachectl is a shell script, to get the module display run:
httpd -M | grep ssl
(httpd is at /sbin/httpd in case you wanted to list the full path).
Outside of the scope of the referenced article, to see the compile settings of apache on RHEL8, run
httpd -V
Hope this helps!
