CentOS+Rails4+Apache2.2でPumaを動かす設定

この記事は、自分の記事「CentOS+Rails4+Apache2.2でPumaを設定する | noriaki blog」の設定部分を備忘的に抜き出したものなので、詳細な手順は記事を参照のこと。

Puma設定

ディレクトリ作成

% mkdir -p tmp/pids
% mkdir -p tmp/sockets

設定ファイル(config/puma.rb)

config/puma.rb

require 'active_support'
require 'active_support/core_ext'

rails_root = Dir.pwd

unless ENV['RACK_ENV'] == 'production'
  environment ENV['RACK_ENV'] || 'development'
  daemonize true  # デーモン化

  workers 0  # 1以上を指定するとCluster化する
  threads 0,2  # スレッド数（最小, 最大）

  bind 'unix://' + File.join(rails_root, 'tmp', 'sockets', 'puma.sock')  # /PATH/TO/MYAPP/tmp/sockets/puma.sock
  port 9293  # Port番号

  pidfile File.join(rails_root, 'tmp', 'pids', 'puma.pid')  # /PATH/TO/MYAPP/tmp/pids/puma.pid
  state_path File.join(rails_root, 'tmp', 'puma.state')  # /PATH/TO/MYAPP/tmp/puma.state

  stdout_redirect(  # pumaのログをlog/以下に出力する。trueは追記モード。
    File.join(rails_root, 'log', 'puma.log'),
    File.join(rails_root, 'log', 'puma-error.log'),
    true
  )

  # pumactlのトークンを指定 via. http://qiita.com/takkkun/items/ecdee7e7dec1bcc9a5b5
  activate_control_app('auto', auth_token: rails_root.camelize.parameterize)
end

Apache設定

アプリ用バーチャルホスト

conf.d/virtualhost_MYAPP.conf

# -*- coding: utf-8; mode: conf; -*-

##
# MYAPP
#
<virtualhost *:80>
    DocumentRoot "/PATH/TO/MYAPP/public" # Railsアプリのpublicディレクトリを指定
    ServerName myapp.example.com  # Railsアプリのドメインを指定

    RewriteLog logs/MYAPP-rewrite_log
    RewriteLogLevel 1
    ErrorLog logs/MYAPP-error_log
    CustomLog logs/MYAPP-access_log combined env=!no_log

    SetEnv RACK_ENV developmen  # Railsアプリの実行環境(development/test/production)

    # for puma config
    include conf.d/puma-conf  # ここでPuma共通設定ファイルを読み込んでいる
    RewriteRule ^/(.*)$ http://0.0.0.0:9293%{REQUEST_URI} [P]  # '9293'のところにはconf/puma.rbで指定したPort番号を設定

    <directory "/PATH/TO/MYAPP/public">
        AllowOverride All
        Options FollowSymLinks -MultiViews
        Order deny,allow
        Allow from all
    </directory>

</virtualhost>

Puma用共通設定ファイル

conf.d/puma-conf

# -*- coding: utf-8; mode: conf; -*-

    # Redirect all requests that don't match a file on disk
    # under DocumentRoot get proxied to Puma
    RewriteEngine On
    RewriteCond %{DOCUMENT_ROOT}/%{REQUEST_FILENAME} !-f

    # Don't allow client to fool Puma into thinking connection is secure
    RequestHeader unset X-Forwarded-Proto

    # Disable ETags (https://github.com/h5bp/server-configs-apache/tree/master/doc#configure-etags)
    # Set Expiration date for all assets to one year in the future
    <locationmatch "^/assets/.*$">
        Header unset ETag
        FileETag None

        ExpiresActive On
        ExpiresDefault "access plus 1 year"
    </locationmatch>

    # Rewrite requests for js and css to gzipped versions
    # if client and server support it
    <locationmatch "^/assets/.*\.(css|js)$">
        RewriteEngine on
        RewriteCond %{HTTP:Accept-Encoding} \b(x-)?gzip\b
        RewriteCond %{REQUEST_FILENAME}.gz -s
        RewriteRule ^(.+)$ $1.gz
    </locationmatch>

    # Set type and headers for gzipped css
    <locationmatch "^/assets/.*\.css\.gz$">
        ForceType text/css
        Header set Content-Encoding gzip
        Header add Vary Accept-Encoding
    </locationmatch>

    # Set type and headers for gzipped js
    <locationmatch "^/assets/.*\.js\.gz$">
        ForceType application/javascript
        Header set Content-Encoding gzip
        Header add Vary Accept-Encoding
    </locationmatch>

    # Compress HTML on the fly
    AddOutputFilterByType DEFLATE text/html
