    These steps have been broken down in to 13 easy to follow steps.

Getting started

    Firstly, this ruby on rails applications is considered outside the Scope of Technical Support.

    Secondly, before you can follow this helpdesk article, you are going to need SSH access. If you don't know how to get SSH access, please review these other helpdesk articles.


    Note: This article does expect you to understand basic command line tools, such as # vim

    1. Create rails_app folder and redmine folder within it then go inside that folder
    2.         # mkdir -p ~/rails_apps/redmine/
              # cd ~/rails_apps/redmine/
              
    3. Download redmine 2.1.4, extract it and move the content out of it, then delete the files not being used.
    4.         # wget http://rubyforge.org/frs/download.php/76589/redmine-2.1.4.tar.gz
              # tar xvzf redmine-2.1.4.tar.gz 
              # mv redmine-2.1.4/* ./
              # rm -rf redmine-2.1.4*
              
    5. Move example files where they can be used
    6.         # cd config
              # mv database.yml.example database.yml
              # mv configuration.yml.example configuration.yml
              
    7. Creating the MySQL Database/User/Password
      1. Log in to your Just Host Control Panel
      2. Within the database section of that cPanel, find the 'MySQL® Databases' Icon.
      3. Create a database, a username, and a password
      4. Assign the user to the database. Full permissions.


    8. Modifying your database.yml file
    9.         # vim database.yml
              
      Modify these lines
                 production:
                  adapter: mysql
                  database: redmine
                  host: localhost
                  username: root
                  password:
                  encoding: utf8
              
    10. Updating the ~/rails_apps/redmine/public/.htaccess file
    11.         # cd ../public/
              # pwd
              
      You should see something similar to this;
              /home#/user/rails_apps/redmine/public
              
              # vim .htaccess
              
      Add these lines
                 Options -MultiViews
                 PassengerResolveSymlinksInDocumentRoot on
                 #Set this to whatever environment you'll be running in
                 RailsEnv production
                 RackBaseURI /
                 SetEnv GEM_HOME /home1/examplec/ruby/gems
              
      Update this line to match the path for #pwd
                 SetEnv GEM_HOME /home#/user/ruby/gems
              
    12. Creating the subdomain
    13. The goal is to point the subdomain to the redmine folder, if you don't have one in mind, you can simply use redmine as your subdomain;
      1. Log in to your Just Host Control Panel
      2. Within the domain section of that cPanel, find the 'Subdomains' Icon.
      3. Choose one of your Domain Names from the drop-down list
      4. Then create a subdomain going to the document root of redmine

    14. Creating the symlink
    15. Now you need to delete the redmine folder, you can delete this from within the ~/public_html directory.
              # rm -rf redmine
      Creating the symlink
              # ln -s ~/rails_app/redmine/public redmine
              
    16. Updating your ~/.bashrc file
    17. Add these lines to the bottom of your ~/.bashrc file
                 export HPATH=$HOME
                 export GEM_HOME=$HPATH/ruby/gems
                 export GEM_PATH=$GEM_HOME:/lib64/ruby/gems/1.9.3
                 export GEM_CACHE=$GEM_HOME/cache
                 export PATH=$PATH:$HPATH/ruby/gems/bin
                 export PATH=$PATH:$HPATH/ruby/gems
              
      after which source your .bashrc file
              # source ~/.bashrc
              
      You will then need to check your rails version
              # rails -v
              
      You should get this message
              Rails 3.2.13
              
      If you see this an error like so
                 Invalid gemspec in [/home#/user/ruby/gems/specifications/mail-2.4.4.gemspec]: invalid date format in specification: "2012-03-14 00:00:00.000000000Z"
                 Invalid gemspec in [/home#/user/ruby/gems/specifications/tilt-1.3.3.gemspec]: invalid date format in specification: "2011-08-25 00:00:00.000000000Z"
              
      Open the file from the error message, in this case /home#/user/ruby/gems/specifications/mail-2.4.4.gemspec modify this line
                 s.date = %q{2012-03-14 00:00:00.000000000Z}
              
      Change it to
                 s.date = %q{2012-03-14}
              
      That should correct that error message. This easy to run command is also viable.
              # find $HOME/ruby/gems/specifications -name \*.gemspec | xargs sed -i "s/\ 00:00:00.000000000Z//"
              
    18. Running bundle install
    19.         # cd ~/rails_apps/redmine/
              # bundle install
              # rake generate_session_store
              
      the # rake generate_session_store is strictly related to redmine, some other applications may use it
      After running the rake if you get this error
                 Invalid gemspec in [/home#/user/ruby/gems/specifications/jquery-rails-2.0.3.gemspec]: invalid date format in specification: "2012-08-16 00:00:00.000000000Z"
              
      Again open that file /home#/user/ruby/gems/specifications/jquery-rails-2.0.3.gemspec and fix the date, if you don't know how to do that read above about 10 lines.
              # bundle install
              
    20. Running generate_session_store or generate_secret_token
    21.         # rake generate_session_store
              
      If you get an error saying that command is deprecated, run this command instead;
              # rake generate_secret_token
              
    22. publishing the site
    23.         # rake db:migrate RAILS_ENV=production
