On an Apache based server
From /usr/share/doc/apache2/README.Debian.gz
Enabling SSL
To enable SSL, type:
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
Everything from here down is outdated.
NOTE: certbot has been updated & some of the rest of the current notes are not quite right. (except for the link immediately following this line...)
This requires that the server have a legit FQDN that works.
But, it's pretty straightforward.
(if ya wanna get fancier... There's a Documentation Page. & command-line options)
Installing on a Webserver Directly accessible from the Internet
(Small note about certbot vs certbot-auto... seems to be some oddity on its name depending on the install... :|
If your machine can't find it by one name, try the other.)
- 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.
- Visit
Installing on a Webserver that will be proxied
NEW! NEW! NEW! NEW! NEW! NEW! NEW! NEW! NEW! NEW! NEW! NEW!
Now you get to retrieve all your certs using the Primary Web Server.
- Assign DNS for the name of the machine you're obtaining certs for
- Wait for the DNS entry to propagate
- You can repeatedly try
systemd-resolve machinename.yourdomain.netuntil it shows your outside address... - (Tho, you might need to do this from outside your local network.)
- You can repeatedly try
- Obtain & install the certificate
- test... (NOTE: If your webserver doesn't respond to the address on port 80, this will fail. You may need to add the address into your VirtualHosts.)
sudo certbot-auto certonly --apache -d machinename.yourdomain.net --dry-run
- remove
--dry-run& repeat to actually get the cert.
- test... (NOTE: If your webserver doesn't respond to the address on port 80, this will fail. You may need to add the address into your VirtualHosts.)
- Copy your shiny new cert to the actual machine it's intended for.
- Set up the proxy in
/etc/apache2/apache2.confor in/etc/apache2/sites-available/machinename.yourdomain.net
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
- Get status of all the certs on the server
certbot-auto certificates
- 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
Getting the certs for a manual install
See CertGetter
CertGetter has been made redundant by using the main webserver on the network as a proxy server.
Installing manual certs on an ESXi server
See SSL - ESXi
