chef実践入門　実機にて実施メモ（5） vagrant,ChefSoloでcentos6.5 + nginx,PHP,Ruby,MySQL環境を構築する

Posted at

Chef実践入門第6章 アプリケーション実行環境の自動構築　を実機にて検証したメモ

#0.環境前提
MacOSX vagrant ,virtualboxインストール済み

#1.Bundlerを導入し、chef,knife-solo,berkshelfをインストール
（Bundler = Gem管理の為のrubyツール）

#環境用ディレクトリの作成
mkdir lnmpr
cd lnmpr

#Bundlerのインストール
sudo gem install bundler

#Gemfile作成
cat <<'EOF' > Gemfile
source 'https://rubygems.org'
gem 'chef'
gem 'knife-solo'
gem 'berkshelf'
EOF

#bundleコマンドの実行
bundle install

#Vagrantfile作成
vagrant init

#2.nginxのインストール
##(1) knife-soloによるcookbook作成

bundle exec knife cookbook create nginx -o ./site-cookbooks

##(2) nginxのレシピ作成

site-cookbooks/nginx/recipes/default.rb
include_recipe "yum-epel"
package "nginx" do
   action :install
end

service "nginx" do
   action [ :enable, :start ]
   supports :status =>true, :restart =>true, :reload =>true
end

##(3) Berksfileを作成し、クックブックの依存関係定義
＊yum,yum-epelは、https://supermarket.getchef.com　から、ローカルのsite-cookbooksに、ダウンロードして入れないと、うまくいかなかった・・ここで結構はまる。

Berksfile
source "https://supermarket.getchef.com"
cookbook 'yum', path: "./site-cookbooks/yum"
cookbook 'yum-epel', path: "./site-cookbooks/yum-epel"
cookbook 'nginx', path: "./site-cookbooks/nginx"

##(4) berks vendorコマンドを実行してコミュニティクックブックのダウンロード

bundle exec berks vendor ./cookbooks

#yum-epel,nginx、依存関係のあるその他のcookbooksが配置されている事を確認
ls -Rla ./cookbooks

##(5) vagrant-omnibusプラグインのインストール

vagrant plugin install vagrant-omnibus
vagrant plugin list

##(6) Vagrantfileの設定

Vagrantfile
VAGRANTFILE_API_VERSION = "2"

Vagrant.configure(VAGRANTFILE_API_VERSION) do |config|
config.vm.hostname = "guest"
config.vm.box = "centos6.5"
config.vm.box_url = "http://opscode-vm-bento.s3.amazonaws.com/vagrant/virtualbox/opscode_centos-6.5-i386_chef-provisionerless.box"

config.vm.network "private_network", ip: "192.168.33.10"

# vagrant-omnibusの有効化
config.omnibus.chef_version = :latest
# Chef solo の設定
config.vm.provision :chef_solo do |chef|
  # クックブックの配置場所
  chef.cookbooks_path = ["./cookbooks","./site-cookbooks"]  
  #適用するクックブックの定義
  chef.run_list = %w[
    recipe[yum]
    recipe[yum-epel]
    recipe[nginx]
  ]
end
end

##(7) 仮想サーバの起動とプロビジョン

vagrant up --provision

##(8) 確認
192.168.33.10にブラウザからアクセスしてnginx画面の確認

#3.PHP5.5のインストール(php,php-fpm,php-opcache)
##(1)knife-soloによるcookbook作成

bundle exec knife cookbook create php-env -o ./site-cookbooks

##(2) レシピ作成

site-cookbooks/php-env/recipes/default.rb
yum_repository 'remi' do
   description 'Les RPM de Remi -Repository'
   baseurl 'http://rpms.famillecollet.com/enterprise/6/remi/x86_64/'
   gpgkey 'http://rpms.famillecollet.com/RPM-GPG-KEY-remi'
   fastestmirror_enabled true
   action :create
end

yum_repository 'remi-php55' do
   description 'Les RPM de remi de PHP5.5 pour Enterprise Linux6'
   baseurl 'http://rpms.famillecollet.com/enterprise/6/php55/$basearch/'
   gpgkey 'http://rpms.famillecollet.com/RPM-GPG-KEY-remi'
   fastestmirror_enabled true
   action :create
end

%w{php php-fpm php-opcache}.each do |pkg|
   package pkg do
   	action :install
   	notifies :restart, "service[php-fpm]"
   end
end

service "php-fpm" do
   action [:enable, :start]
end

##(3) Vagrantfile編集

Vagrantfile
    chef.run_list = %w[
      recipe[yum-epel]
      recipe[nginx]
      #以下行を追加
      recipe[php-env]
    ]

##(4) Berksfileの編集

以下を追加

Berksfile
cookbook "php-env", path:"./site-cookbooks/php-env"

yum list installed | grep php 
exit

#3.nginxの設定ファイル変更　(nginxとPHP-FPM連携)
##(1)templateの作成

site-cookbooks/nginx/templates/default/nginx.conf.erb
user nginx;
worker_processes 1;

error_log	/var/log/nginx/error.log warn;
pid	/var/run/nginx.pid;

events{
	worker_connections 1024;
}

	include	/etc/nginx/mime.types;
	default_type application/octes-stream;
	log_format main '$remote_addr - $remote_user [$time_local] "$request"'
		'$status $body_bytes_sent "$http_referer"'
		'"$http_user_agent" "http_x_forwarded_for"';
	access_log	/var/log/nginx/access.log main;
	sendfile 	on;
	keepalive_timeout 65;

	server{
		listen 80 default_server;
		server_name _;

		location / {
			root	/usr/share/nginx/html;
			index	index.html index.htm index.php;
		}

		_page 404	/404.html;
		location = /404.html {
			root /usr/share/nginx/html;
		}

		# redirect server error pages to the static page /50x.html
		#
		error_page 500 502 503 504 /50x.html;
		location = /50x.html{
			root	/usr/share/nginx/html;
		}
		<% if node['nginx']['env'].include?("php") %>
		location ~ \.php$ {
			fastcgi_pass	127.0.0.1:9000;
			fastcgi_index	index.php;
			fastcgi_param	SCRIPT_FILENAME $document_root$fastcgi_script_name;
			include		fastcgi_params;	

		}
		<% end %>
	} 

}

##(2)nginx.conf.erbを有効とするようnginxのレシピに追記
以下を追記

site-cookbooks/nginx/recipes/default.rb
 template 'nginx.conf' do
 	path	'/etc/nginx/nginx.conf'
 	source	"nginx.conf.erb"

		'"$http_user_agent" "http_x_forwarded_for"';
	access_log	/var/log/nginx/access.log main;
	sendfile 	on;
	keepalive_timeout 65;

	#以下Unicorn連携用の記述1/2
	<% if node['nginx']['env'].include?("ruby") %>
	upstream unicorn{
		server unix:/tmp/unicorn.sock;
	}
	<% end %>
	#ここまで

	server{
		listen 80 default_server;
		server_name _;

		location / {
			root	/usr/share/nginx/html;
			index	index.html index.htm index.php;
		}

		error_page 404	/404.html;
		location = /404.html {
			root /usr/share/nginx/html;
		}

		# redirect server error pages to the static page /50x.html
		#
		error_page 500 502 503 504 /50x.html;
		location = /50x.html{
			root	/usr/share/nginx/html;
		}
		<% if node['nginx']['env'].include?("php") %>
			location ~ \.php$ {
			fastcgi_pass	127.0.0.1:9000;
			fastcgi_index	index.php;
			fastcgi_param	SCRIPT_FILENAME $document_root$fastcgi_script_name;
			include		fastcgi_params;	
			}
		<% end %>
		#以下Unicorn連携用の記述2/2
		<% if node['nginx']['env'].include?("ruby") %>
			location /unicorn{
			rewrite ^/unicorn/(.+) /$1 break;
			proxy_pass http://unicorn/$1;
			}
		<% end %>	
		#ここまで
	} 
}

##(3) Attributeで初期値を設定

Vagrantfile
#変更前
    chef.json = {
      nginx: {
        env: ["php"]
      }
    }
#変更後
    chef.json = {
      nginx: {
        env: ["php","ruby"]
      }
    }

##(4) berks vendorコマンドを実行

bundle exec berks vendor ./cookbooks

##(5) プロビジョン実行

VAGRANT_LOG=info vagrant provision >&vagrant.log

##(6)動作確認用にRubyOnRailsのプロジェクトを作成する

gem 'rails', '4.0.4'
gem 'sqlite3'
gem 'sass-rails','~>4.0.2'
gem 'uglifier', '>=1.3.0'
gem 'coffee-rails','~>4.0.0'
gem 'jquery-rails'
gem 'turbolinks'
gem 'jbuilder','~>1.2'

group :doc do
	gem 'sdoc',require: false
end

gem 'unicorn'

bundle install

##(7)Unicornの設定ファイルを作成
ゲスト側でUnicorn設定ファイルを作成

test_unicorn/config/unicorn.rb

site-cookbooks/nodejs/recipes/default.rb
%w{gcc-c++}.each do |pkg|
	package pkg do
		action :install
	end
end
remote_file "tmp/#{node['nodejs']['filename']}" do
	 source "#{node['nodejs']['remote_uri']}"
end

bash "install nodejs" do
	user "root"
	cwd "/tmp"
	code <<-EOC
		tar xvzf #{node['nodejs']['filename']}
		cd #{node['nodejs']['dirname']}
		make
		make install
	EOC
end
