How to renew only one domain with certbot?

I have multiple domains with multiple certificates:

$ ll /etc/letsencrypt/live/
> domain1.com
> domain2.com
> domain3.com
> ...

I need to renew only domain1.com, but the command certbot renew renews certificates for all domains. How can I renew certain certificate explicitly?

Solution 1:

Renew a single certificate using renew with the --cert-name option.

(certonly creates a certificate for one or more domains, replacing it if exists).

Example

certbot renew --cert-name domain1.com --dry-run

Remove --dry-run to actually renew.

Cert-name != Domain name

Note that the value supplied to --cert-name option is a certificate name (not a domain name) found using

certbot certificates

Returning a list like

-------------------------------------------------------------------------------
Found the following certs:
  Certificate Name: myfundomains.com
    Domains: myfundomains.com
    Expiry Date: 2018-05-04 04:28:05+00:00 (VALID: 67 days)
    Certificate Path: /etc/letsencrypt/live/myfundomains.com/fullchain.pem
    Private Key Path: /etc/letsencrypt/live/myfundomains.com/privkey.pem
  Certificate Name: ask.myfundomain.com
    Domains: ask.myfundomain.com
    Expiry Date: 2018-03-13 18:59:40+00:00 (VALID: 16 days)
    Certificate Path: /etc/letsencrypt/live/ask.myfundomain.com/fullchain.pem
    Private Key Path: /etc/letsencrypt/live/ask.myfundomain.com/privkey.pem
  Certificate Name: forums.myfundomain.com
    Domains: forums.myfundomain.com forum.myfundomain.com
    Expiry Date: 2018-04-11 16:39:18+00:00 (VALID: 45 days)
    Certificate Path: /etc/letsencrypt/live/forums.myfundomain.com/fullchain.pem
    Private Key Path: /etc/letsencrypt/live/forums.myfundomain.com/privkey.pem
-------------------------------------------------------------------------------

Notice how the third Certificate name (forums.myfundomain.com) contains multiple domains:

forums.myfundomains.com
forum.myfundomains.com

Restart Apache / nginx

-------------------------------------------------------------------------------
new certificate deployed without reload, fullchain is
/etc/letsencrypt/live/ask.myfundomain.com/fullchain.pem
-------------------------------------------------------------------------------

Remember to restart your webserver to make use of the new certificate.

Solution 2:

You can use this command (for Apache server):

certbot --apache certonly -n -d domain1.com

--apache for apache server, use --nginx flag for nginx server
-n option execute the command without prompt
-d domain1.com to execute only for domain1.com

You can test with --dry-run, and you can use --pre-hook and --post-hook like with certbot renew
