Apache2+PassengerでRailsを動かす

Ubuntu Apache

手順

前提
  • Apache2はインストール済み
  • WEBrickでRailsアプリの動作確認済み
    • $ rvm use 1.8.7-head@rails3.0 --default のRVM環境でやります
passengerインストール
$ gem install passenger
passenger-install-apache2-module実行
$ passenger-install-apache2-module

Enterキーで進んでいくと、

Installation instructions for required software

 * To install Curl development headers with SSL support:
   Please run apt-get install libcurl4-openssl-dev or libcurl4-gnutls-dev, whichever you prefer.

 * To install Apache 2 development headers:
   Please run apt-get install apache2-prefork-dev as root.

 * To install Apache Portable Runtime (APR) development headers:
   Please run apt-get install libapr1-dev as root.

 * To install Apache Portable Runtime Utility (APU) development headers:
   Please run apt-get install libaprutil1-dev as root.

If the aforementioned instructions didn't solve your problem, then please take
a look at the Users Guide:

  /home/atsm/.rvm/gems/ruby-1.8.7-head@rails3.0/gems/passenger-3.0.7/doc/Users guide Apache.html

とあるのでインストールする。

$ sudo aptitude install libcurl4-openssl-dev
$ sudo aptitude install apache2-prefork-dev
$ sudo aptitude install libapr1-dev
$ sudo aptitude install libaprutil1-dev

再度passenger-install-apache2-moduleを実行する。

$ passenger-install-apache2-module

Enterキーで進んでいくと、今度は成功。

--------------------------------------------
The Apache 2 module was successfully installed.

Please edit your Apache configuration file, and add these lines:

   LoadModule passenger_module /home/atsm/.rvm/gems/ruby-1.8.7-head@rails3.0/gems/passenger-3.0.7/ext/apache2/mod_passenger.so
   PassengerRoot /home/atsm/.rvm/gems/ruby-1.8.7-head@rails3.0/gems/passenger-3.0.7
   PassengerRuby /home/atsm/.rvm/wrappers/ruby-1.8.7-head@rails3.0/ruby

After you restart Apache, you are ready to deploy any number of Ruby on Rails
applications on Apache, without any further Ruby on Rails-specific
configuration!

Press ENTER to continue.


--------------------------------------------
Deploying a Ruby on Rails application: an example

Suppose you have a Rails application in /somewhere. Add a virtual host to your
Apache configuration file and set its DocumentRoot to /somewhere/public:

   <VirtualHost *:80>
      ServerName www.yourhost.com
      DocumentRoot /somewhere/public    # <-- be sure to point to 'public'!
      <Directory /somewhere/public>
         AllowOverride all              # <-- relax Apache security settings
         Options -MultiViews            # <-- MultiViews must be turned off
      </Directory>
   </VirtualHost>

And that's it! You may also want to check the Users Guide for security and
optimization tips, troubleshooting and other useful information:

とあるのでメモしておく。

/etc/apache2/apache2.conf編集

まず

LoadModule passenger_module /home/atsm/.rvm/gems/ruby-1.8.7-head@rails3.0/gems/passenger-3.0.7/ext/apache2/mod_passenger.so
PassengerRoot /home/atsm/.rvm/gems/ruby-1.8.7-head@rails3.0/gems/passenger-3.0.7
PassengerRuby /home/atsm/.rvm/wrappers/ruby-1.8.7-head@rails3.0/ruby

をApache設定ファイルに追記する。

$ cd /etc/apache2
$ sudo cp -p apache2.conf apache2.conf.bak
$ sudo vim apache2.conf

ファイルの最後に追記する。

LoadModule passenger_module /home/atsm/.rvm/gems/ruby-1.8.7-head@rails3.0/gems/passenger-3.0.7/ext/apache2/mod_passenger.so
PassengerRoot /home/atsm/.rvm/gems/ruby-1.8.7-head@rails3.0/gems/passenger-3.0.7
PassengerRuby /home/atsm/.rvm/wrappers/ruby-1.8.7-head@rails3.0/ruby
確認用Railsアプリを作成
$ cd /var
$ sudo chmod 777 www
$ cd www
$ rails new test

 24                 Allow from all
 25         </Directory>
 26
 27         ErrorLog ${APACHE_LOG_DIR}/error.log
 28
 29         # Possible values include: debug, info, notice, warn, error, crit,
 30         # alert, emerg.
 31         LogLevel warn
 32

 37         Options Indexes MultiViews FollowSymLinks
 38         AllowOverride None
 39         Order deny,allow
 40         Deny from all
 41         Allow from 127.0.0.0/255.0.0.0 ::1/128
 42     </Directory>
 43
 44 </VirtualHost>

のようなかんじ。

※追記（2011/05/20）
passengerで起動すると何も指定がないと「production」（本番）環境で動くので、5行目のRailsEnv developmentを追記。
Apache再起動
$ sudo /etc/init.d/apache2 restart
確認
ゲストOS
http://localhost/
ホストOS
http://ゲストOSのIP/

で確認。
今度はホストOSからアクセスしても問題なく早い。ということはWEBrickの問題だったのかなあ。
