Could not find ssl_module; not installing certificate

Help

Hello, and thank you for your help!

I've answered the questions below. Yes, I know the stack is old, but it's a development server that will only be accessible to me and my partner.

Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g. crt.sh | example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.

My domain is: lisamacneil.com

I ran this command: certbot --apache

It produced this output: Complete result:
Saving debug log to /var/log/letsencrypt/letsencrypt.log
Could not find ssl_module; not disabling session tickets.

Which names would you like to activate HTTPS for?

Do you have mod_ssl installed?

Did you install httpd from yum?

D'oh! mod_ssl was not installed. I've never seen this before -- and yes, I installed httpd from yum.

Thank you so much!

Is there nothing newer?

Not under CentOS 7--security fixes are backported, but it's going to stick with Apache 2.4.6 for its lifespan (and the same is true with most of its other packages).
