Since it doesn’t seem like your operating system has a packaged version of Certbot, you should use our certbot-auto script to get a copy:
wget https://dl.eff.org/certbot-auto chmod a+x certbot-auto
certbot-auto accepts the same flags as certbot; it installs all of its own dependencies and updates the client code automatically.
Certbot has a fairly solid beta-quality Apache plugin, which is supported on many platforms, and automates certificate installation.
$ sudo ./path/to/certbot-auto --apache
Running this command will get a certificate for you and have Certbot edit your Apache configuration automatically to serve it. If you’re feeling more conservative and would like to make the changes to your Apache configuration by hand, you can use the certonlysubcommand:
$ sudo ./path/to/certbot-auto --apachecertonly
To learn more about how to use Certbot read our documentation.
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:
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)' &&
More detailed information and options about renewal can be found in the full documentation.
0 0 1 * * sudo /root/certbot-auto renew 5 0 1 * * service httpd restart
