ChefSoloの使い方

chef

ChefServerは3台必要でしたが、ChefSoloは1台でChefを実行できます。

今回はChefSoloを使ってWebサーバを構築します。 

サーバの準備

vagrantを使っています。

Vagrant file

$ vim Vagrantfile
VAGRANTFILE_API_VERSION = "2"
Vagrant.configure(VAGRANTFILE_API_VERSION) do |config|
  config.vm.define :centos2 do |dev|
    dev.vm.box               = "chef/centos-6.5"
    dev.vm.hostname          = "dev102"
    dev.vm.network :private_network, ip: "10.0.0.102"
  end
end

構築

$ vagrant up centos2

ログイン

$ vagrant ssh centos2

 

ChefSoloをインストール

$ wget https://www.opscode.com/chef/install.sh
$ sudo bash install.sh -v 11.4.0

$ vi cookbook/sample/recipes/default.rb
package "httpd" do

end
service "httpd" do
 action [ :enable, :start ]
end
cookbook_file "/var/www/html/index.html" do
 source "index.html"
 mode "0644"
end

$ vi cookbook/sample/files/default/index.html
<html>
<body>
 <h1>Hello, world!</h1>
</body>
</html>

$ vi localhost.json
{
 "run_list":[
 "recipe[sample]"
 ]
}

$ vi solo.rb
file_cashe_path "/tmp/chef-solo"
cookbook_path ["/home/vagrant/chef-repo/cookbook"]
