ISPConfig 3 Autoinstaller
{FW}*


Usage: ispc3-ai.sh [<argument>] [...]

This script automatically installs all needed packages for an ISPConfig 3 setup using the guidelines from the "Perfect Server Setup" howtos on www.howtoforge.com.

Possible arguments are:
	--help			->Show this help page
	--debug			->Enable verbose logging (logs each command with the exit code)
	--interactive	->Don\'t install ISPConfig in non-interactive mode. This is needed if you want to use expert mode, e. g. to install a slave server that shall be integrated into an existing multiserver setup.
	--use-nginx		->Use nginx webserver instead of apache2
	--no-web		->Do not use ISPConfig on this server to manage webserver setting and don\'t install nginx/apache. This will also prevent installing an ISPConfig UI and implies --no-roundcube as well as --no-pma
	--no-mail		->Do not use ISPConfig on this server to manage mailserver settings. This will install postfix for sending system mails, but not dovecot and not configure any settings for ISPConfig mail.
	--no-dns		->Do not use ISPConfig on this server to manage DNS entries. Bind will be installed for local DNS caching / resolving only.
	--no-firewall	->Do not install ufw and tell ISPConfig to not manage firewall settings on this server.
	--no-roundcube	->Do not install roundcube webmail.
	--no-pma		->Do not install PHPMyAdmin on this server.
	--i-know-what-i-am-doing
					->Prevent the autoinstaller to ask for confirmation before continuing to reconfigure the server.
