Redmine

h1. HowTo configure Apache to run Redmine

{{toc}}

These notes assume you already have Redmine running via the webrick server and are looking to get Redmine running via your existing Apache installation.   Most of the commands assume you are in the root installation directory of redmine, so be sure to change directory there before starting.

h2. For CentOS 5

h3. Assumptions

* OS is CentOS 5

* Web server is Apache 2

** mod_cgi is enabled

** name based virtual servers are being used

** the web server runs under the user apache, group apache

h3. Basic Steps

* Install Redmine per the installation instructions and get it running with webrick.

* Kill the webrick session

* Copy the public/dispatch.cgi.example to public/dispatch.cgi

* Edit public/dispatch.cgi to fix the shell script invocation to read:

  @#!/usr/local/bin/ruby@

* Make sure public/dispatch.cgi has execute permissions via:

  @# chmod 755 public/dispatch.cgi@

* Update the config/environment.rb file to force the rails environment to production, simply uncomment this line at the start of the file:

  @ENV['RAILS_ENV'] ||= 'production'@

* Add your virtual host entry to the apache configuration file (/etc/httpd/conf/httpd.conf).  We installed redmine into the /live/redmine folder on our server.  _Note: be sure to point your DocumentRoot to the public sub-folder!_

<pre>

    <VirtualHost *:80>

        ServerName redmine.<YOUR-DOMAIN>.com

        ServerAdmin webmaster@<YOUR-DOMAIN>.com

        DocumentRoot /live/redmine/public/

        ErrorLog logs/redmine_error_log

        <Directory "/live/redmine/public/">

                Options Indexes ExecCGI FollowSymLinks

                Order allow,deny

                Allow from all

                AllowOverride all

        </Directory>

    </VirtualHost>

</pre>

* Make sure your files, log, tmp, and vendor directories are all accessible (read/write) by user apache, group apache. We did that via a change of ownership:

  @# chown -R apache:apache files log tmp vendor@

h3. Error Messages and Resolutions

  * @Rails requires RubyGems >= 0.9.4. Please install RubyGems@

    Look for rogue versions of ruby binaries.  We had an older version in /usr/bin/ruby as well as /usr/local/bin/ruby.

  * @Premature script headers@

    This is the generic "got something before the Content-Type: header in a CGI script" error from Apache.  Run dispatch.cgi (see below) and see what comes out BEFORE the Content-Type: directive.

h2. Helpful Commands

 * @# which ruby@

   tells you which ruby binary is being run when the fully-qualified-filename has not been specified.

 * @# find / -name ruby@

   searches your entire system for any file named ruby, warning: can take a while on large filesystems.

 * @# ruby -v@

   tell you what version of ruby you are running by default

 * @#public/dispatch.cgi@

   runs the dispatch CGI script.   It should spit out HTML that start with @Content-Type: text/html; charset=utf-8@, if ANYTHING precedes the Content-Type text you will get a "premature script headers" error in the Apache log files.
