Deprecating official Rex packages

As part of our efforts to simplify maintenance around RexOps projects, we have decided to stop building Rex packages on our side. We recommend relying on OS packages maintained by the various distributions in their respective upstream repositories, or to install Rex from CPAN.

Rex

• Hardware and Information gathering

  Now you can get information of the servers hardware and configuration.

  ⁠use Rex::Hardware;
  ⁠use Data::Dumper;
  ⁠
  ⁠desc "Get Hardware Information";
  ⁠task "hw-info", "testsystem", sub {
  ⁠  my %hw = Rex::Hardware->get(qw/ Host Kernel Memory Network Swap /);
  ⁠
  ⁠  print Dumper( \%hw );
  ⁠};    

  Will produce the following example output:

  ⁠$VAR1 = {
  ⁠  'Network' => {
  ⁠    'networkdevices'       => [ 'eth0', 'wlan0' ],
  ⁠    'networkconfiguration' => {
  ⁠      'wlan0' => {
  ⁠        'broadcast' => '192.168.2.255',
  ⁠        'ip'        => '192.168.2.229',
  ⁠        'netmask'   => '255.255.255.0',
  ⁠        'mac'       => '00:21:5C:5C:1E:5F'
  ⁠      },
  ⁠      'eth0' => {
  ⁠        'broadcast' => undef,
  ⁠        'ip'        => undef,
  ⁠        'netmask'   => undef,
  ⁠        'mac'       => '00:1C:25:94:B0:85'
  ⁠      }
  ⁠    }
  ⁠  },
  ⁠  'Memory' => {
  ⁠    'shared'  => '0',
  ⁠    'buffers' => '36',
  ⁠    'free'    => '3168',
  ⁠    'used'    => '792',
  ⁠    'total'   => '3961',
  ⁠    'cached'  => '407'
  ⁠  },
  ⁠  'Kernel' => {
  ⁠    'kernelversion' => '#1 SMP PREEMPT 2011-02-21 10:34:10 +0100',
  ⁠    'architecture'  => 'x86_64',
  ⁠    'kernel'        => 'Linux',
  ⁠    'kernelrelease' => '2.6.37.1-1.2-desktop'
  ⁠  },
  ⁠  'Swap' => {
  ⁠    'free'  => '3812',
  ⁠    'used'  => '0',
  ⁠    'total' => '3812'
  ⁠  },
  ⁠  'Host' => {
  ⁠    'domain'                 => 'site',
  ⁠    'manufacturer'           => 'LENOVO',
  ⁠    'hostname'               => 'linux-ymf0.site',
  ⁠    'operatingsystemrelease' => '11.4',
  ⁠    'operatingsystem'        => 'SuSE'
  ⁠  }
  ⁠};    

• Install Packages

  Support for apt, yum and zypper (OpenSuSE)

  Example:

  ⁠# include for ,,install'' Function
  ⁠use Rex::Commands::Pkg;
  ⁠
  ⁠# include for ,,operating_system_is'' Function
  ⁠use Rex::Commands::Gather;
  ⁠
  ⁠user "root";
  ⁠
  ⁠private_key "/Users/jan/.ssh/id_rsa";
  ⁠public_key "/Users/jan/.ssh/is_rsa.pub";
  ⁠
  ⁠# group servers
  ⁠group "test" => "debian01", "centos01", "suse01";
  ⁠
  ⁠# run tasks in parallel
  ⁠parallelism 2;
  ⁠
  ⁠desc "Prepare System";
  ⁠task "prepare",
  ⁠  group => "test",
  ⁠  sub {
  ⁠
  ⁠  # check if operating system is CentOS, because on CentOS vim is
  ⁠  # available through the package "vim-enhanced".
  ⁠  if ( operating_system_is("CentOS") ) {
  ⁠    install package => "vim-enhanced";
  ⁠  }
  ⁠  else {
  ⁠    install package => "vim";
  ⁠  }
  ⁠
  ⁠  install package => "mc";
  ⁠
  ⁠  };    

  This task will install vim and mc on all the 3 systems.
