Symfony 2 Kickstart

Install symfony2 with composer.phar

    composer.phar create-project symfony/framework-standard-edition demoproject

in /etc/sudoer add following line

    username ALL = NOPASSWD: /sbin/shutdown

also to allow at group level

    %admin  ALL = NOPASSWD: /sbin/shutdown

now one can use shutdown command without sudo password, but shutdown command still needs sudo command like

    sudo shutdown -h now

    rsync --verbose --links --delete-excluded -ae ssh /var/www/myfolder/* user@ipaddress:/var/www/myfolder
