    You can choose to set the ruby version to the chef installed version, instead of the one included in the operating system repositories.

    OS installed version.

    $ which ruby
/usr/bin/ruby
$ ruby --version
ruby 2.0.0p648 (2015-12-16) [x86_64-linux]

    Set ruby version to the chef dk installed version.

    $ echo 'eval "$(chef shell-init bash)"' >> ~/.bash_profile
$ source .bash_profile
$ which ruby
/opt/chefdk/embedded/bin/ruby

    Install git latest or OS package repository version.
    see link: https://git-scm.com/download/linux

    $ sudo yum install git

    You can use one of two methods to create the chef-repo, using the starter kit with the chef-server or manually create it. This guide uses the manual method.

    $ chef generate app chef-repo

    Create the .chef directory. Which should contain the following files.

    • knife.rb
    • ORGANIZATION-validator.pem
    • USER.pem
    $ mkdir -p ~/chef-repo/.chef

    You chef-repo should contain these directories, mkdir them.
    chef-repo/
    .chef/ << the hidden directory
    certificates/
    config/
    cookbooks/
    data_bags
    environments/
    roles/

    Add entries to .gitignore file.

    $ pwd
/home/chef/chef-repo
$ echo '.chef' >> ~/chef-repo/.gitignore

**Create an organization.** Example as per chef website link. The ORGANIZATION-validator.pem is stored in chef.key
```bash
$ chef-server-ctl org-create chef "Chef Software, Inc." -f /tmp/chef.key

    Create a user. Example as per chef website.

    $ chef-server-ctl user-create grantmc Grant McLennan [email protected] p@s5w0rD! -f /tmp/grantmc.key

    Create a knife.rb file following the example from chef website. Replacing the pem file names for your file names.

    current_dir = File.dirname(__FILE__)
log_level                :info
log_location             STDOUT
node_name                'node_name'
client_key               "#{current_dir}/USER.pem"
validation_client_name   'ORG_NAME-validator'
validation_key           "#{current_dir}/ORGANIZATION-validator.pem"
chef_server_url          'https://api.chef.io/organizations/ORG_NAME'
cache_type               'BasicFile'
cache_options( :path => "#{ENV['HOME']}/.chef/checksums" )
cookbook_path            ["#{current_dir}/../cookbooks"]

    Add Ruby to the PATH.

    $ echo 'export PATH="/opt/chefdk/embedded/bin:$PATH"' >> ~/.configuration_file && source ~/.configuration_file
$ echo 'export PATH="/opt/chefdk/embedded/bin:$PATH"' >> ~/.bash_profile && source ~/.bash_profile

    Fetch the ssl certificate from the chef server.

    $ knife ssl fetch
WARNING: Certificates from goldenhost will be fetched and placed in your trusted_cert
directory (/home/chef/chef-repo/.chef/trusted_certs).

Knife has no means to verify these are the correct certificates. You should
verify the authenticity of these certificates after downloading.

Adding certificate for goldenhost in /home/chef/chef-repo/.chef/trusted_certs/goldenhost.crt

    Verify the workstation can connect to the chef server. In this example it just listed the server.

    $ knife client list
goldenhost-validator
chef 52
