Nginx on openSUSE Tumbleweed
Install
Certbot is packaged for your OS, so to install it simply run the following command:
$ sudo zypper install certbot python-certbot-nginx
Installing DNS plugins
Certbot's DNS plugins are available for your system. These plugins can be used to automate obtaining a wildcard certificate from Let's Encrypt's ACMEv2 server. To use one of these plugins, you must have configured DNS for the domain you want to obtain a certificate for with a DNS provider that Certbot has a plugin for. A list of these plugins and more information about using them can be found here. To install one of these plugins, run the installation command above but replace certbot python-certbot-nginx with python-certbot-dns-PLUGIN, where PLUGIN is the name of the plugin you want to install. For instance, for the RFC2136 plugin this would be python-certbot-dns-rfc2136.
Get Started
Certbot has an Nginx plugin, which is supported on many platforms, and automates certificate installation.
$ sudo certbot --nginx
Running this command will get a certificate for you and have Certbot edit your Nginx configuration automatically to serve it. If you're feeling more conservative and would like to make the changes to your Nginx configuration by hand, you can use the certonly subcommand:
$ sudo certbot --nginx certonly
If you want to obtain a wildcard certificate using Let's Encrypt's new ACMEv2 server, you'll also need to use one of Certbot's DNS plugins. To do this, make sure the plugin for your DNS provider is installed using the instructions above and run a command like the following:
$ sudo certbot -a dns-plugin -i nginx -d "*.example.com" -d example.com --server https://acme-v02.api.letsencrypt.org/directory
You'll need to replace dns-plugin with the name of the DNS plugin you want to use. You may also need to provide additional flags such as the path your API credentials as described in the documentation for the DNS plugin linked above.
To learn more about how to use Certbot read our documentation.Automating renewal
Certbot can be configured to renew your certificates automatically before they expire. Since Let's Encrypt certificates last for 90 days, it's highly advisable to take advantage of this feature. You can test automatic renewal for your certificates by running this command:
$ sudo certbot renew --dry-runIf that appears to be working correctly, you can arrange for automatic renewal by adding a cron job or systemd timer which runs the following:
certbot renew
An example cron job might look like this, which will run at noon and midnight every day:
0 0,12 * * * python -c 'import random; import time; time.sleep(random.random() * 3600)' && certbot renew
More detailed information and options about renewal can be found in the full documentation.
