初めてのRuby!!Passenger(mod_rails)をとりあえず入れてみて

今まで、Rubyっていうものは聴いたことはあったけど、一度も触ったことがなかった。
なんとなく、Ruby on Railsには興味はあったし、どんなものかも知っていたけど、
実行環境を作るのが面倒くさそうだった。

が、なんかmod_railsというのが出たらしい。
結構簡単に、環境が作れるらしい。

ということで、早速インストールしてみることにした。

前提：
以下が既にインストール済みとする。
Apache2
Ruby 1.8以降？

まず、どうやらRuby関係の何かを入れるためにgemsというのが必要らしい。
ということで、インストール。
aptであったので、さっくりとaptから。

# apt-get install rubygems

あとで、知ったことだがここでとりあえずgemsをアップデートしておいた
ほうがいいらしい。（たぶん）
（自分の場合は失敗して、再インストールすることになってしまった）

# gem update –system

でさっそく、Passenger(mod_rails）をインストールしようとしたら・・・。

# gem install passenger
Bulk updating Gem source index for: http://gems.rubyforge.org
ERROR: While executing gem … (Gem::GemNotFoundException)
Could not find passenger (> 0) in any repository

なんか怒られてしまった。
どうやら、railsを先にいれないといけないらしい。
Railsってつまりは、Ruby on RailsをやるためのFrameworkかな？

ということで、さっくりとインストール。
これも、gemsから出きるらしい。

# gem install -v=2.0.2 rails -y

気を取り直して、Passenger(mod_rails)のインストール。
これもやっぱり、先ほどと一緒でgemsから。

で仕上げに、以下をやらないといけないらしい。

# passenger-install-apache2-module

Welcome to the Passenger Apache 2 module installer, v1.0.5.

This installer will guide you through the entire installation process. It
shouldn't take more than 3 minutes in total.

Here's what you can expect from the installation process:

1. The Apache 2 module will be installed for you.
2. You'll learn how to configure Apache.
3. You'll learn how to deploy a Ruby on Rails application.

Don't worry if anything goes wrong. This installer will advise you on how to
solve any problems.

Press Enter to continue, or Ctrl-C to abort.

The Apache 2 module was successfully installed.

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

   LoadModule passenger_module /var/lib/gems/1.8/gems/passenger-1.0.5/ext/apache2/mod_passenger.so
   RailsSpawnServer /var/lib/gems/1.8/gems/passenger-1.0.5/bin/passenger-spawn-server
   RailsRuby /usr/bin/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 Ruby on Rails application in /somewhere. Add a virtual host
to your Apache configuration file, and set its DocumentRoot to
/somewhere/public, like this:

   <VirtualHost *:80>
      ServerName www.yourhost.com
      DocumentRoot /somewhere/public
   </VirtualHost>

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

/var/lib/gems/1.8/gems/passenger-1.0.5/doc/Users guide.html

Enjoy Passenger, a product of Phusion (www.phusion.nl)

すばらしい。
エラーもなく案外あっさりとインストールできてしまった。
しかも、最後に、httpd.confの設定例まで表示された。

httpd.confの設定は後回しにして。
ついでに、RubyとMySQLを連携させるためのモジュールらしきものもいれておく。
（これが必要なのかは確認していない・・・）

# apt-get install MySQL-ruby

これできっと完璧。
ということで、httpd.confの編集。

# vim /etc/apache2/conf/httpd.conf
(以下を追加)
LoadModule passenger_module /var/lib/gems/1.8/gems/passenger-1.0.5/ext/apache2/mod_passenger.so
RailsSpawnServer /var/lib/gems/1.8/gems/passenger-1.0.5/bin/passenger-spawn-server
RailsRuby /usr/bin/ruby

ということで、Apacheを再起動。

# service apache2 restart

ということで、一通りインストールは完了した。
