My redmine setup log on Server 2008 SP2 x64 Web Edition, IIS7, native FastCGI and Microsoft URL Rewrite
Base on 2 best article I found by googling
with something I found may be useful.
First of all - prepare files
Then – Install files
Step 1: Install Ruby 1.8.6.
According to Redmine Installation Guide ( http://www.redmine.org/wiki/redmine/RedmineInstall ), Support Ruby version is 1.8.6. & 1.8.7.
Step 2: Install rails
gem install rails
Step 3: Install RubyForIIS
Because the fcgi extension not bundle in rails.
Afterward, test fcgi
c:\ruby\bin\>irb
irb(main):001:0> require 'fcgi'
=> true
irb(main):002:0> quit
Step 4: Extract Redmine files to target folder
e.g. C:\inetpub\redmine
below I will call it [Redmine Path]
Step 5: Create folder and Set folder permission (Step 7 on Redmine Installation Guide)
make a folder called \tmp and \public\plugin_assets under [Redmine Path]
cd [Redmine Path]
md tmp
md public\plugin_assets
and assign tmp, files, log, public\plugin_assets IWAM account ( or Network Service account) has full control
Step 6: Create Database
Just create database, user account and password (Step 3 on Redmine Installation Guide).
make sure the default database character is “utf-8″ because the create database script did not assign.
Step 7: Config files
copy [Redmine Path]\config\database.y ml.example to [Redmine Path]\config\database. yml and edit the “production” database connection settings
Step 8: run database create script on redmine root folder
rake db:migrate RAILS_ENV=”production” and create session store
cd [Redmine Path]
rake config/initializers/session_store.rb
Step 9: test site by using build-in webrick (step 8 on Redmine Installation Guide).
ruby script/server webrick -e production
Step 10:IIS config
Create a web site and set physical path to redmine public folder
Copy/rename [Redmine Path]\public\dispatch.fcgi.example to [Redmine Path]\public\dispatch.fcgi
Modify [Redmine Path]\config\environment.rb, uncomment line "# ENV['RAILS_ENV'] ||= 'production'" to assign the environment to production
Copy/rename [Redmine Path]\config\email.yml.example to [Redmine Path]\config\email.yml and setup Outgoing email settings
Module Setting
URL Mapping
Request path: dispatch.fcgi
Module: FastCgiModule
Executable (optional):
c:\Ruby\bin\Ruby.exe|[Redmine Path]\public\dispatch.fcgi production

Step 11:URL Rewrite
paste following url rewrite config into web.config under <system.webServer> branch
<rewrite>
<rules>
<clear />
<rule name="Imported Rule 1-1" stopProcessing="true">
<match url="^(.*)(\.png)(\.)$" ignoreCase="true" />
<conditions logicalGrouping="MatchAll" />
<action type="Rewrite" url="{R:1}.png" appendQueryString="false" />
</rule>
<rule name="Imported Rule 1">
<match url="^$" ignoreCase="false" />
<action type="Rewrite" url="index.html" appendQueryString="true" />
</rule>
<rule name="Imported Rule 2">
<match url="^([^.]+)$" ignoreCase="false" />
<action type="Rewrite" url="{R:1}.html" appendQueryString="true" />
</rule>
<rule name="Imported Rule 3" stopProcessing="true">
<match url="^(.*)$" ignoreCase="false" />
<conditions logicalGrouping="MatchAll">
<add input="{REQUEST_FILENAME}" matchType="IsFile" negate="true" pattern="" ignoreCase="false" />
</conditions>
<action type="Rewrite" url="dispatch.fcgi" appendQueryString="true" />
</rule>
</rules>
</rewrite>
Step 12:Minor configuration
[Redmine Path]\config\environment.rb
uncomment following line to force rails environment to production
ENV['RAILS_ENV'] ||= 'production'
