Not sure about third-party certificates. It’s easiest to save your money and run the
box install letsencrypt command. However, the certificate should be able to get set in these two locations (divided by the key and certificate) ::
/etc/ssl/certs/ for your
/etc/ssl/private/ for your
You can then change these 2 lines in your default-ssl.conf file to point to your certificate you installed.
Then issue a restart to apache with
service apache2 restart
As per ::
“You’re almost done. Upload file to /.well-known/pki-validation/ public directory”
Seems like youd need to make the directory at your QuickBox directory located at /srv/rutorrent/home. I am only guessing as I have never seen a purchased certificate have some sort of install command, other than generating the needed CSR. In this case, it may be better for you to check their docs.
