I was determined to figure this out myself, but I've been at it for a total of more than 10 hours, and I just can't figure this out. First, let me detail my environment (which I cannot change):

• Server version: Apache/2.2.15 (Unix)
• Ruby version: ruby 1.9.3p448
• Rails version: Rails 4.0.1
• Passenger version: Phusion Passenger version 4.0.5
• Redmine version: 2.3.3

I have followed the Redmine instructions all the way through the test webserver to check that installation was successful with this command: ruby script/rails server webrick -e production

The roadblock which I cannot overcome is getting Apache and Passenger to interpret and properly serve Redmine. I have searched pretty much every possible link within the first 10 pages or so of Google results. Everywhere I go I come across conflicting/contradicting/outdated information.

We have a "weird" setup with Apache (which I inherited and cannot change). Redmine needs to be served through SSL, but Apache already has another website it's serving through SSL called Twiki. By "weird", what I mean is that our file structure is entirely different from all the tutorials out there on this version of Apache which have directories like "available-sites" and such.

Here are the abbreviated versions of some of our config files:

/etc/httpd/conf/httpd.conf (the global configuration file --- note that NO VirtualHost is defined here):

ServerRoot "/etc/httpd"

...

LoadModule passenger_module /usr/local/pkg/ruby/1.9.3-p448/lib/ruby/gems/1.9.1/gems/passenger-4.0.5/libout/apache2/mod_passenger.so
PassengerRoot /usr/local/pkg/ruby/1.9.3-p448/lib/ruby/gems/1.9.1/gems/passenger-4.0.5
PassengerDefaultRuby /usr/local/pkg/ruby/1.9.3-p448/bin/ruby

Include conf.d/*.conf

...

User apache
Group apache

...

DocumentRoot "/var/www/html"

So just to clarify, the above httpd.conf file does NOT have a VirtualHost section.

/etc/httpd/conf.d/ssl.conf (defines the VirtualHost for ssl):

Listen 443

<VirtualHost _default_:443>
SSLEngine on
...
SSLCertificateFile /etc/pki/tls/certs/localhost.crt
</VirtualHost>

/etc/httpd/conf.d/twiki.conf (this works just fine --- note this does NOT define a VirtualHost):

ScriptAlias /twiki/bin/ "/var/www/twiki/bin/"
Alias /twiki/ "/var/www/twiki/"

<Directory "/var/www/twiki/bin">
        AllowOverride None
        Order Deny,Allow
        Deny from all
        AuthType Basic
        AuthName "our team"
        AuthBasicProvider ldap
        ...a lot of ldap and authorization stuff

        Options ExecCGI FollowSymLinks
        SetHandler cgi-script
</Directory>

/etc/httpd/conf.d/redmine.conf:

Alias /redmine/ "/var/www/redmine/public/"

<Directory "/var/www/redmine/public">
    Options Indexes ExecCGI FollowSymLinks
    Order allow,deny
    Allow from all
    AllowOverride all
</Directory>

The amazing thing is that this doesn't completely NOT work: I can successfully open up https://someserver/redmine/ with SSL and the https://someserver/twiki/ site remains unaffected. This tells me that it IS possible to have two separate sites up with one SSL configuration, so I don't think that's the problem.

The problem is is that it opens up to the file index. I can navigate around my Redmine file structure, but no code ever gets executed. For example, there is a file included with Redmine called dispatch.fcgi in the public folder. https://someserver/redmine/dispatch.fcgi opens, but just as plain text code in the browser. As I understand it, in the case of using Passenger, CGI and FastCGI stuff is irrelevant/unused.
