Installing Packages
Installing packages is easy. You can use the pkg function for this.
use Rex -feature => ['1.0'];user "root";password "f00b4r";task "prepare_system", group => "frontends", sub {pkg "apache2",ensure => "present";};
If you have to install multiple packages you can use an array so that you don't have to write that much.
use Rex -feature => ['1.0'];user "root";password "f00b4r";task "prepare_system", group => "frontends", sub {pkg ["apache2", "libphp5-apache2", "mysql-server"],ensure => "present";};
If you need to write a distribution independent module you can also use the case statement.
user Rex -base;user "root";password "f00b4r";
task "prepare_system", group => "frontends", sub {my $packages = case operating_system,Debian => ["apache2", "libphp5-apache2"],CentOS => ["httpd", "php5"],pkg $packages,ensure => "present";};
