安装特定版本的包Ec2 chef

Question

I want to install a specific version of package PHP in Amazon Linux with chef 12, this is my code that i used:

node.override['apache']['version'] = '2.4'   

case node.default[:platform]
  when 'rhel', 'fedora', 'suse', 'centos'
    node.override['php']['packages'] = ['php71w']

    # add the EPEL repo
    yum_repository 'epel' do
      description 'Extra Packages for Enterprise Linux'
      mirrorlist 'http://mirrors.fedoraproject.org/mirrorlist?repo=epel-7&arch=x86_64'
      gpgkey 'http://dl.fedoraproject.org/pub/epel/RPM-GPG-KEY-EPEL-7'
      action :create
    end

    when 'amazon'
    node.override['php']['packages'] = ['php71]

    include_recipe "php::package"
    include_recipe "php::ini"         
    end    
include_recipe "build-essential"

It installed this verison "PHP 7.1.25 " but i want this version "PHP 7.1.15 " what should i do ?
