Redmine

How did you install passenger, did you use a package (yum?) or the passenger gem?
What exactly is the issue you're facing?

Gem I think :-)... I followed this guide http://www.redmine.org/projects/redmine/wiki/Install_Redmine_25x_on_Centos_65_complete.

After that I tried to use the " Using Redmine::Utils (preferred solution)" and "Using Rails features" in this guide http://www.redmine.org/projects/redmine/wiki/HowTo_Install_Redmine_in_a_sub-URI and also this https://www.phusionpassenger.com/documentation/Users%20guide%20Apache.html#deploying_rails_to_sub_uri...

Tried also this way http://www.redmine.org/projects/redmine/wiki/HowTo_Install_Redmine_on_subdirectory_%28sub-URI%29_on_Apache

I had different results with different conf... I would try to reproduce errors I got and post here.

With this conf I can see the sub-Uri correctly but only the list of files instead of formatted site.

<VirtualHost *:80>
    ServerName servername.domain.int
    DocumentRoot /var/www/html
    <Directory /redmine/public>
        Allow from all
        Options -MultiViews
        # Uncomment this if you're on Apache >= 2.4:
        #Require all granted
    </Directory>

    # These have been added:
    Alias /redmine /var/www/html/redmine/public
    <Location /redmine>
        PassengerBaseURI /redmine
        PassengerAppRoot /redmine/public
    </Location>
    <Directory /var/www/html/redmine/public>
        Allow from all
        Options -MultiViews
        # Uncomment this if you're on Apache >= 2.4:
        #Require all granted
    </Directory>
</VirtualHost>

Did you enable the passenger module in apache?
I've not used RedHat / Centos in years, but grep -Ri passenger /etc/apache2/* and check.
Do you have the files passenger.conf and and passenger.load?
If so, please post the contents of both.

Here is Passenger.conf

LoadModule passenger_module /usr/local/rvm/gems/ruby-1.9.3-p547/gems/passenger-4.0.45/buildout/apache2/mod_passenger.so
 <IfModule mod_passenger.c>
   PassengerRoot /usr/local/rvm/gems/ruby-1.9.3-p547/gems/passenger-4.0.45
   PassengerDefaultRuby /usr/local/rvm/gems/ruby-1.9.3-p547/wrappers/ruby
</IfModule>

Attached the result of the command issued.

I did another test, here is the content of redmine.conf

<VirtualHost *:80>
    ServerName servername.domain.int
    DocumentRoot /var/www/html
    <Directory "/var/www/html/redmine/public/">
    Options Indexes ExecCGI FollowSymLinks
        Allow from all
    Order allow,deny
    AllowOverride all
        Options -MultiViews
        # Uncomment this if you're on Apache >= 2.4:
        #Require all granted
    </Directory>

    # These have been added:
    Alias /redmine /var/www/html/redmine/public
    <Location /redmine>
        PassengerBaseURI /redmine
        PassengerAppRoot /redmine/public
    </Location>
</VirtualHost>

and the environment.rb

# Load the rails application

require File.expand_path('../application', __FILE__)

# Make sure there's no plugin in vendor/plugin before starting

vendor_plugins_dir = File.join(Rails.root, "vendor", "plugins")

if Dir.glob(File.join(vendor_plugins_dir, "*")).any?

  $stderr.puts "Plugins in vendor/plugins (#{vendor_plugins_dir}) are no longer allowed. " +

    "Please, put your Redmine plugins in the `plugins` directory at the root of your " +

    "Redmine directory (#{File.join(Rails.root, "plugins")})" 

  exit 1

end

# Initialize the rails application

RedmineApp::Application.initialize!
Redmine::Utils::relative_url_root = "/redmine" 
#ActionController::AbstractRequest.relative_url_root = "/redmine" 
#ActionController::Base.relative_url_root = "/redmine" 

and .htaccess

# General Apache options
<IfModule mod_fastcgi.c>
        AddHandler fastcgi-script .fcgi
</IfModule>
<IfModule mod_fcgid.c>
        AddHandler fcgid-script .fcgi
</IfModule>
Options +FollowSymLinks +ExecCGI

# If you don't want Rails to look in certain directories,
# use the following rewrite rules so that Apache won't rewrite certain requests
#
# Example:
#   RewriteCond %{REQUEST_URI} ^/notrails.*
#   RewriteRule .* - [L]

# Redirect all requests not available on the filesystem to Rails
# By default the cgi dispatcher is used which is very slow
#
# For better performance replace the dispatcher with the fastcgi one
#
# Example:
#   RewriteRule ^(.*)$ dispatch.fcgi [QSA,L]
RewriteEngine On

# If your Rails application is accessed via an Alias directive,
# then you MUST also set the RewriteBase in this htaccess file.
#
# Example:
#   Alias /redmine /var/www/html/redmine/public
#   RewriteBase /redmine

RewriteRule ^$ index.html [QSA]
RewriteRule ^([^.]+)$ $1.html [QSA]
RewriteCond %{REQUEST_FILENAME} !-f
<IfModule mod_fastcgi.c>
        RewriteRule ^(.*)$ dispatch.fcgi [QSA,L]
</IfModule>
<IfModule mod_fcgid.c>
        RewriteRule ^(.*)$ dispatch.fcgi [QSA,L]
</IfModule>

# In case Rails experiences terminal errors
# Instead of displaying this message you can supply a file here which will be rendered instead
#
# Example:
#   ErrorDocument 500 /500.html

ErrorDocument 500 "<h2>Application error</h2>Rails application failed to start properly" 

The result is now "Rails application failed to start properly"

Now it is working.

During my tests I have also edited the file additional_environment.rb... Just mv the file and everything seems ok now.

Good to hear, have fun with redmine!
