In addition to capturing the minimal steps required to install a Chef 10 Server on Ubuntu, I also wanted to capture the steps for CentOS. Unfortunately, Ruby 1.9 isn’t available in the default distribution repositories, and almost all third party repositories are quite out of date. As such, I’ll use the Ruby 1.8.7 that comes with CentOS, despite being an EOL version of Ruby.

Similar steps are also available on the Chef wiki, too.

This does not include any customization to the installation and takes everything as default. This will all change when Chef 11 is released.

These steps were performed on a default server install of CentOS 6.3.

Install required packages.

yum install ruby ruby-devel rubygems wget gcc gcc-c++ kernel-devel make

Update RubyGems.

gem update --system

Install Chef.

gem install chef --no-ri --no-rdoc

Configure chef-solo.

mkdir -p /etc/chef
vi /etc/chef/solo.rb

The config file should look like this:

file_cache_path "/tmp/chef-solo"
cookbook_path "/tmp/chef-solo/cookbooks"
recipe_url ""

Run chef-solo with the chef-server::rubygems-install recipe.

chef-solo -o chef-server::rubygems-install

The WebUI is not enabled by default. This can be done by setting an attribute, see the chef-server cookbook for more information.

Next, create a new API client that will be used to upload cookbooks.

knife configure -i

Change the chef_server_url to use the FQDN or IP address of the Chef Server. Change the path for the validation key. The .chef/knife.rb file should look something like this:

log_level                :info
log_location             STDOUT
node_name                'jtimberman'
client_key               '/root/.chef/jtimberman.pem'
validation_client_name   'chef-validator'
validation_key           '/root/.chef/validation.pem'
chef_server_url          ''
cache_type               'BasicFile'
cache_options( :path => '/root/.chef/checksums' )

Copy the validation key (/etc/chef/validation.pem) to the .chef directory.

cp /etc/chef/validation.pem ~/.chef

Verify that the API client and configuration file work.

knife client list

The newly created API client should be listed. Mine is jtimberman. Now the Chef Server is ready to use.
