SBN - Copying Certs

To copy certs for a machine from your proxy server (Replace Machine.Domain.TLD with the proper name for your machine...) (&, of course, user & WebServer may need adjusting...)

In this example,

• Machine.Domain.TLD is the full name of the machine you're copying the certs to.
• WebServer is the name of your web/proxy server

1. Install certbot on the machine you're putting the certs onto & create the live directory where the certs will live. (Unverified Note: You might not actually need to install certbot on the proxied machine. You may be able to just create the /etc/letsencrypt directory, then the live directory...)
   • ssh Machine
   • sudo apt install certbot
   • sudo mkdir /etc/letsencrypt/live
2. Sign into your proxy server & make sure you can SSH into the target machine from there.
   • ssh webserver
     • ssh Machine
     • then exit when you've succeeded (this tells webserver how to get there...)
3. Then you can use scp to copy the certs.
   • sudo scp -r /etc/letsencrypt/live/Machine.Domain.TLD user@Machine:~
4. Then ssh back into the target machine & move the certs into their proper location
   • sudo mv Machine.Domain.TLD /etc/letsencrypt/live/
5. And tell Apache about the certs
   • sudo vi /etc/apache2/sites-available/default-ssl.conf

SSLCertificateFile /etc/letsencrypt/live/Machine.Domain.TLD/fullchain.pem
SSLCertificateKeyFile /etc/letsencrypt/live/Machine.Domain.TLD/privkey.pem

replaces:

SSLCertificateFile      /etc/ssl/certs/ssl-cert-snakeoil.pem
SSLCertificateKeyFile /etc/ssl/private/ssl-cert-snakeoil.key

Restart Apache:

• sudo systemctl restart apache2
