Installation of CENTOS 6x

Hello, sorry I’m new, I’m performing the installation on a dedicated server with centos 6x, I now install everything and are in the section where I have to conclude with cd / root / letsencrypt
./letsencrypt-auto --text --agree-tos --email email@domain.com certonly --renew-by-default --webroot --webroot-path / home / cPanelUser / public_html / - d domain.com - d www.domain.com

I know that I need to enter my email peràò I wonder should I replace domain.com with the domain names that I intend to install the script? Or in this case, enter the userid root domain and leaving the rest? Thank you

Yes, domain.com should be replaced by your own domain. And www.domain.com should also be replaced.

You may have a try for my bash client: https://github.com/Neilpang/le
It’s easy to use.
