Xen DomUでRedmine + Phusion Passenger + Ruby Enterprise Edition


Xen DomUで、Redmineを運用する。物理マシンの場合の手順は、『Redmine 1.1をCentOS5.5にインストールする手順』に詳しいが、Xen DomUにこれと同じ手順を適用すると、コンソールや/var/log/messagesあたりに次のようなメッセージが表示されることがある
4gb seg fixup, process ruby (pid 1270), cs:ip 73:00867ba6
4gb seg fixup, process ruby (pid 1270), cs:ip 73:001c30f1
4gb seg fixup, process ruby (pid 1270), cs:ip 73:00867ba6
4gb seg fixup, process ruby (pid 1270), cs:ip 73:001c30f1
printk: 96 messages suppressed.
4gb seg fixup, process ruby (pid 1270), cs:ip 73:00867ba6
これは、『4gb seg fixup REE XEN』で報告されている問題と同じで、ここで挙げられている通り、環境変数を設定してからRuby Enterprise Edition(以下、REE)をインストールすればよい。以下作業ログ。

Welcome to the Ruby Enterprise Edition installer
This installer will help you install Ruby Enterprise Edition 1.8.7-2011.03.
Don't worry, none of your system files will be touched if you don't want them
to, so there is no risk that things will screw up.

You can expect this from the installation process:

1. Ruby Enterprise Edition will be compiled and optimized for speed for this
2. Ruby on Rails will be installed for Ruby Enterprise Edition.
3. You will learn how to tell Phusion Passenger to use Ruby Enterprise
Edition instead of regular Ruby.

Ruby Enterprise Edition is successfully installed!
If want to use Phusion Passenger (http://www.modrails.com) in combination
with Ruby Enterprise Edition, then you must reinstall Phusion Passenger against
Ruby Enterprise Edition, as follows:


Make sure you don't forget to paste the Apache configuration directives that
the installer gives you.

If you ever want to uninstall Ruby Enterprise Edition, simply remove this

Welcome to the Phusion Passenger Apache 2 module installer, v3.0.6.

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.[Enter]を入力


Checking for required software...

* GNU C++ compiler... found at /usr/bin/g++
* Curl development headers with SSL support... found
* OpenSSL development headers... found

The Apache 2 module was successfully installed.

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

LoadModule passenger_module /opt/ruby-enterprise-1.8.7-2011.03/lib/ruby/gems/1.8/gems/passenger-3.0.6/ext/apache2/mod_passenger.so
PassengerRoot /opt/ruby-enterprise-1.8.7-2011.03/lib/ruby/gems/1.8/gems/passenger-3.0.6
PassengerRuby /opt/ruby-enterprise-1.8.7-2011.03/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

Press ENTER to continue.[Enter]を入力

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:

ServerName www.yourhost.com
DocumentRoot /somewhere/public # <-- be sure to point to 'public'!

AllowOverride all # <-- relax Apache security settings
Options -MultiViews # <-- MultiViews must be turned off

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