certbot

$ sudo certbot certonly --webroot --webroot-path ${path-to-webroot} --domain ${subdomain-example-com}

try on your machine

This command is used to obtain a SSL/TLS certificate for a specific subdomain using Certbot, a free and open-source software tool designed for automatically managing SSL/TLS certificates.

Here's a breakdown of the command and its options:

sudo: It runs the command with administrative privileges (root access), which is often required to modify certain system settings and files.
certbot: This is the actual Certbot command-line utility.
certonly: It specifies that the intention is to only obtain the certificate and not carry out any installation or renewal.
--webroot: It is a Certbot plugin that performs the domain validation by placing a temporary file in the specified webroot directory.
--webroot-path ${path-to-webroot}: It denotes the web root directory for the subdomain in question. You need to replace ${path-to-webroot} with the actual path to the webroot directory.
--domain ${subdomain-example-com}: It specifies the subdomain for which the SSL/TLS certificate is being obtained. You need to replace ${subdomain-example-com} with the actual subdomain.

Overall, this command tells Certbot to generate a SSL/TLS certificate for the specified subdomain by performing domain validation using the webroot method and the provided webroot path.
