$ kitchen converge default-centos65

Now, let's get to some coding. First, let's use the package resource to install the httpd pack-
age using yum install by editing recipes/default.rb , as shown in Example 7-10 .

Example 7-10. chefdk/apache/recipes/default.rb
#
# Cookbook Name:: apache
# Recipe:: default

package "httpd" ddo
action :install
end end

Run kitchen converge again to check your work. We also encourage you to use kitchen
login to inspect the node to verify that your recipe is doing what you expect. Log in to the
node, and verify that the httpd service is installed with the following command. Be sure to
exit back out to your host prompt when you are done:

$ kitchen converge default-centos65
$ kitchen login default-centos65

Welcome to your Packer-built virtual machine.
[vagrant@default-centos65 ~]$ rpm -q httpd
httpd-2.2.15-31.el6.centos.x86_64
[vagrant@default-centos65 ~]$ exit
logout
Connection to 127.0.0.1 closed.

The httpd service is indeed installed! The rpm -q command queries the rpm package man-
ager database to see if a package containing the name is present on the system.

If you look at the Chef documentation on the package resource , package calls one of many
providers based on the platform and platform_family returned by ohai . Because our
platform is rhel , the yum_package provider is used.
