The apache plugin is not working; there may be problems with your existing configuration

At this point letsencrypt has created your certificate in /etc/letsencrypt/live/example.com/cert.pem, as well as your private key (privkey.pem) and a file with both your certificate and any intermediaries (fullchain.pem).

The remaining steps are independent from Let’s Encrypt, so basically any guide for installing SSL certificates on apache would work. The simplest version - and I don’t really recommend this for production - would probably be something like this:

<VirtualHost *:443>
   # ...

   SSLEngine on
   SSLCertificateFile    /etc/letsencrypt/live/example.com/cert.pem
   SSLCertificateKeyFile /etc/letsencrypt/live/example.com/privkey.pem
   SSLCertificateChainFile /etc/letsencrypt/live/example.com/fullchain.pem
</VirtualHost>

Mozilla provides a more complete sample configuration here:
