While hidden from the UI, you can use the plugin to obtain a certificate by specifying will prepare a self-signed SSL certificate for you with the challenge validation appropriately encoded into a subject Alternat Names entry.You will need to configure your SSL server to present this challenge SSL certificate to the ACME server using SNI.The generation of a new certificate counts against several rate limits that are intended to prevent abuse of the ACME protocol, as described here.This command attempts to renew any previously-obtained certificates that expire in less than 30 days.If you’re getting a certificate for many domains at once, the plugin needs to know where each domain’s files are served from, which could potentially be a separate directory for each domain.When requesting a certificate for multiple domains, each domain will use the most recently specified .These plugins can modify your webserver’s configuration to serve your website over HTTPS using certificates obtained by certbot.
An example request made to your web server would look like: The Nginx plugin has been distributed with Certbot since version 0.9.0 and should work for most configurations.
This may be useful if some domains specified in a certificate no longer point at this system.
Whenever you obtain a new certificate in any of these ways, the new certificate exists alongside any previously obtained certificates, whether or not the previous certificates have expired.
tells Certbot to create a separate, unrelated certificate with the same domains as an existing certificate.
This certificate is saved completely separately from the prior one.For example, if you have a single certificate obtained using the standalone plugin, you might need to stop the webserver before renewing so standalone can bind to the necessary ports, and then restart it after the plugin is finished. A failing hook doesn’t directly cause Certbot to exit with a non-zero exit code, but since Certbot exits with a non-zero exit code when renewals fail, a failed hook causing renewal failures will indirectly result in a non-zero exit code.
