h1. Installation Instructions

Open Design Engine (ODE) is based on "Redmine":http://redmine.org.  The official installation method is to install the "Bitnami Redmine Stack":http://bitnami.org/stack/redmine, apply some custom configuration to the stack, and then upgrade the installed Redmine instance to the ODE source code.  Support for other stacks (or bootstrapped installations) will come with future releases.  With luck, one or more of the stack providers will add ODE to their list of supported stacks.  

Note, these instructions assume you are running the Ubuntu VM image of the Bitnami Redmine Stack and are *running all commands under* @sudo@.  They were tested with "version 1.1.3":http://bitnami.org/files/stacks/redmine/1.1.3-0/bitnami-redmine-1.1.3-0-ubuntu-10.10.zip in "VMWare Player":http://www.vmware.com/products/player/. 

Useful Paths
* @(bitnami_base) = /opt/bitnami@ in VM images

Steps to install ODE
* Import the Bitnami Redmine Stack into VMWare (the free VMWare Player is supported)
* Configure Redmine to run at http://hostname/ instead of http://hostname/redmine
** Edit @(bitnami_base)/apache2/conf/httpd.conf@ and comment out the line:
<pre>
DocumentRoot "/opt/bitnami/apache2/htdocs"
</pre>
** Edit @(bitnami_base)/apps/redmine/conf/redmine.conf@ to match the following (the key areas are the addition of the virtual host section and changing all references of @/redmine@ to @/@):
<pre>
<VirtualHost *:80>
  ServerAdmin haha.huhu.com
  ServerName server.our.lan
  ServerAlias server
  ErrorLog "logs/error.log" 
  CustomLog "logs/access.log" combined

  # The number of balancer members depends on the number of mongrels running
  # We use only one mongrel on port 3001 by default for the BitNami Cloud Hosting
  # Please remove the others like 3002 above in such a case.

</pre>
** Edit @(bitnami_base)/apps/redmine/config/mongrel_cluster.yml@ and change references to @prefix: /redmine@ to @prefix: @
** Restart Redmine by running:
<pre>
(bitnami_base)/ctlscript stop
(bitnami_base)/ctlscript start
</pre>
* Configure SVN in Redmine
** Install dependencies
<pre>
apt-get update
apt-get install build-essential
apt-get install zlib1g-dev
(bitnami_base)/perl/bin/cpan  # accept defaults and choose CPAN servers
cpan> install Test::Simple
cpan> install DBI
cpan> install DBD::mysql
cpan> quit
apt-get install libapache2-svn libapache-dbi-perl libapache2-mod-perl2 libdbd-mysql-perl libdigest-sha1-perl libauthen-simple-ldap-perl
</pre>
** Enable newly installed apache modules by editing @(bitnami_base)/apache/conf/httpd.conf@
*** Uncomment approximately line 108:
<pre>
LoadModule dav_svn_module modules/mod_dav_svn.so
</pre>
*** Add a line at the end of the load modules list for mod_perl:
<pre>
LoadModule perl_module modules/mod_perl.so
</pre>
** Copy Redmine.pm into the perl library
<pre>
cp (bitnami_base)/apps/redmine/extra/svn/Redmine.pm (bitnami_base)/perl/lib/site_perl/5.8.8/i686-linux/Apache/
</pre> 
** Create the directory structure for the svn repositories (_Note, ODE is setup to store all project related content in the @(bitnami_base)@ directory, so it uses a non-traditional location to store the svn repositories._)
<pre>
cd (bitnami_base)
mkdir repos
chown root:daemon repos
chmod 0755 repos
cd repos
mkdir svn
chown root:daemon svn
chmod 0750 svn
</pre>
** Document the following production values in @(bitnami_base)/apps/redmine/config/database.yml@:
*** username
*** password
*** socket
*** database
*** host
** Edit @(bitnami_base)/apps/redmine/conf/redmine.conf@ to configure apache to host the svn repositories
*** Add the following line between @RewriteEngine On@ and the first @RewriteCond@ to prevent calls to svn from being forwarded to Redmine:
<pre>
RewriteCond %{REQUEST_URI} !/svn(/|$)
</pre>
