NetMan - SSL Certs

On an Apache based server

From /usr/share/doc/apache2/README.Debian.gz

Enabling SSL

To enable SSL, type (as user root):

sudo a2ensite default-ssl

sudo a2enmod ssl

If you want to use self-signed certificates, you should install the ssl-cert
package (see below). Otherwise, just adjust the SSLCertificateKeyFile and SSLCertificateFile directives in '/etc/apache2/sites-available/default-ssl.conf' to point to your SSL certificate. Then restart apache:

sudo systemctl restart apache2

The SSL key file should only be readable by root; the certificate file may be globally readable. These files are read by the Apache parent process which runs as root, and it is therefore not necessary to make the files readable by the www-data user.

Getting proper certificates onto the machine

This requires that the server have a legit FQDN that works.

But, it's pretty straightforward.

Installing on a Webserver Directly accessible from the Internet

(Coming soon... I promise...)

• install certbot (assuming a LAMP install)
  • sudo apt-get install certbot python-certbot-apache
• Ensure that your firewall is pointing both port 80 and port 443 at this machine. (This is your Webserver after all...)
• Obtain & install the certificate
  • sudo certbot --apache
• Verify that automatic renewal works
  • sudo certbot renew --dry-run
• Confirm that certbot worked
  • Visit https://yourwebsite.com/ in your browser and look for the lock icon in the URL bar.
  • (Somewhat obviously... yourwebsite.com should be replaced with your actual address...)
  • If you want to geek out over it... check it at SSL Labs.

Installing on a Webserver that will be proxied

(This part of the instructions will probably change...)

For now... We'll pretend this is a normal Webserver. Automatic renewal is gonna fail.

• install certbot (assuming a LAMP install)
  • sudo apt-get install certbot python-certbot-apache
• Make the machine visible on port 80 to the internet. (see CertGetter)
• Obtain & install the certificate
  • sudo certbot --apache

A trick or two...

• Add certification for the root of the domain (i.e.: no "www.")
  • sudo /usr/local/bin/certbot-auto certonly -d www.FOOBAR.net -d FOOBAR.net
• Create certificates for other machines on the network
  • Still working on this one...scroll a little bit further...

SSL for the rest of the network
