letsencrypt-auto [SUBCOMMAND] [options] [-d domain] [-d domain] ...
The Let's Encrypt agent can obtain and install HTTPS/TLS/SSL certificates. By
default, it will attempt to use a webserver both for obtaining and installing
the cert. Major SUBCOMMANDS are:
(default) run Obtain & install a cert in your current webserver
certonly Obtain cert, but do not install it (aka "auth")
install Install a previously obtained cert in a server
renew Renew previously obtained certs that are near expiry
revoke Revoke a previously obtained certificate
rollback Rollback server configuration changes made during install
config_changes Show changes made to server config during installation
plugins Display information about installed plugins
Choice of server plugins for obtaining and installing cert:
--apache Use the Apache plugin for authentication & installation
--standalone Run a standalone webserver for authentication
(nginx support is experimental, buggy, and not installed by default)
--webroot Place files in a server's webroot folder for authentication
OR use different plugins to obtain (authenticate) the cert and then install it:
--authenticator standalone --installer apache
More detailed help:
-h, --help [topic] print this message, or detailed help on a topic;
the available topics are:
all, automation, paths, security, testing, or any of the subcommands or
plugins (certonly, install, nginx, apache, standalone, webroot, etc)
