certbot:tldr:d4613
This command is using the Certbot tool with sudo (which provides administrative privileges) to generate a test SSL certificate for a specific subdomain (--domain) using the webroot method (--webroot).
Here is the breakdown of the command:
-
sudo
: This is a command used in Unix-like operating systems to run a command with administrative privileges. It allows Certbot to execute commands that require elevated permissions. -
certbot
: Certbot is a command-line tool used to obtain and manage SSL certificates from the Let's Encrypt certificate authority. In this case, it is being used to generate an SSL certificate. -
--webroot
: This flag specifies the method to use for obtaining the SSL certificate. The webroot method requires you to place a specific file in the webroot directory of your subdomain to prove domain ownership. -
--webroot-path ${path-to-webroot}
: This option sets the webroot path where the required verification file will be placed. You need to replace${path-to-webroot}
with the actual directory path on your system. -
--domain ${subdomain-example-com}
: This option specifies the domain (subdomain) for which the certificate will be generated. You need to replace${subdomain-example-com}
with the actual subdomain name. -
--test-cert
: This flag tells Certbot to generate a test certificate instead of a live, production-ready certificate. Test certificates have a shorter validity period and are useful for testing purposes or setting up initial configurations.
By running this command with the appropriate parameters, Certbot will verify domain ownership and generate a test SSL certificate for the specified subdomain using the webroot method.
