"1. httpd -k start -c "DocumentRoot /var/www/html_debug/": Start up Apache using an alternative DocumentRoot. This is useful if you're trying out alternative versions of your web site, as it avoids editing the DocumentRoot option. You can also use -c to set any other directive. Note that -c processes the directive after reading the config files (so it will overwrite config file settings), whereas -C will process the directive before the config files."
