mongrel_cluster -> mod_rails (Passenger 1.0.1)

Rails linux

http://www.moongift.jp/2008/04/passenger/

mod_rails (Passengenr)がリリースされたので、mongrel_cluster & mod_proxy_balancer から mod_rails にswitchしてみた。サーバはCentOS 5。
Debian系だとUbuntuは6.06と7.10,DebianはSarge,Etch,Lenny/Sidがテストされてる？

$ sudo gem install passenger
$ sudo passenger-install-apache2-module
Welcome to the Passenger Apache 2 module installer.

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 /usr/local/lib/ruby/gems/1.8/gems/passenger-1.0.1/ext/apache2/mod_passenger.so
   RailsSpawnServer /usr/local/lib/ruby/gems/1.8/gems/passenger-1.0.1/bin/passenger-spawn-server
   RailsRuby /usr/local/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:

  /usr/local/lib/ruby/gems/1.8/gems/passenger-1.0.1/doc/Users guide.html

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

適宜コピってconfファイルを編集。

$ sudo vi /etc/httpd/conf.d/railsapp.conf
LoadModule passenger_module /usr/local/lib/ruby/gems/1.8/gems/passenger-1.0.1/ext/apache2/mod_passenger.so
RailsSpawnServer /usr/local/lib/ruby/gems/1.8/gems/passenger-1.0.1/bin/passenger-spawn-server
RailsRuby /usr/local/bin/ruby

NameVirtualHost *:80
<VirtualHost *:80>
   ServerName www.katahirado.jp
   DocumentRoot /u/apps/katahirado/current/public
</VirtualHost>

<VirtualHost *:80>
   ServerName railsapp2.katahirado.jp
   DocumentRoot /u/apps/railsapp2/current/public
</VirtualHost>

<VirtualHost *:80>
   ServerName railsapp3.katahirado.jp
   DocumentRoot /u/apps/railsapp3/current/public
</VirtualHost>

<VirtualHost *:80>
   ServerName railsapp4.katahirado.jp
   DocumentRoot /u/apps/railsapp4/current/public
</VirtualHost>

超お手軽。mongrel_cluster より楽。
計測してないけど、体感では速度も結構速いと感じた。
今まで4アプリ×2でmongrelを8つ動かしてたんだけど、topでさらっと確認してみた分には、mod_rails の方がメモリ使用量少ないっぽい。
しばらく運用してみよう。
