Meu código phpweb.pp

execute 'apt-get update'

exec { 'apt-update': command => '/usr/bin/apt-get update' }

package { ['php7.2' ,'php7.2-mysql'] : require => Exec['apt-update'], ensure => installed, }

exec { 'run-php7': require => Package['php7.2'], command => '/usr/bin/php -S 192.168.0.191:80 -t /vagrant/src &' }

Poderiam me ajudar?
