The aim of this document is to set up the grader's web interface rails application so that users can access it via http://your-web-server/grader. The application uses mongrel_cluster as its load balancer.

Install dependencies
The grader makes use of HAML and RSpec. You also need BlueCloth if you want nice formatting for tasks. So you need to install them first.
gem install haml --no-ri gem install rspec --no-ri gem install BlueCloth --no-ri sudo apt-get install libopenssl-ruby1.8
Check out the Grader Web Interface
First, make a directory that will contain all the grader files. In my case, I make a directory called "grader" inside my home directory.
mkdir ~/grader
Inside the directory, you check out the web interface.
svn co http://theory.cpe.ku.ac.th/grader/web/trunk/ ~/grader/web
Create routes.rb
cd ~/grader/web/config cp routes.rb.SAMPLE routes.rb
Set up the Database
cd ~/grader/web/config cp database.yml.SAMPLE database.yml
Then, edit database.yml so that it reflects the database setting of your machine.
Note: In Ubuntu, the database socket is not located at /tmp/mysql.sock as it is in other distributions. You need to add one extra line in database.yml to tell rails this:
adapter: mysql socket: /var/run/mysqld/mysqld.sock database: ioi username: ioi password: whateverpassword host: localhost
Next, you do the migration:
cd ~/grader/web rake db:migrate
Check your MySQL to see if the tables actually appear.
Test the Grader for the First Time
Then, run the server
ruby script/server
Go check http://localhost:3000. You can login as root and the password is ioionrails. You should change the password immediately and logout.
Set up Mongrel Cluster
We assume that you already have mongrel_cluster installed in your system.
Have mongrel create a config file for you:
mongrel_rails cluster::configure -e production -p 5000 -a 127.0.0.1 -N 2 -c ~/grader/web mkdir ~/grader/web/tmp/pids
The config file is located at ~/grader/web/config/mongrel_cluster.yml. It should look like this:
--- cwd: /home/ioi/grader/web log_file: log/mongrel.log port: "5000" environment: production address: 127.0.0.1 pid_file: tmp/pids/mongrel.pid servers: 2
Next, start the server.
cd ~/grader/web mongrel_rails cluster::start
See if it works by checking out http://localhost:5000/.
Connect mongrel_cluster with apache2
First, we edit apache2's configuration.
cd /etc/apache2/sites-available sudo emacs default
Paste the following snippet of code into the bottom part of the file before </VirtualHost>
Alias /grader "/home/ioi/grader/web/public" <directory "/home/ioi/grader/web/public/"> Options FollowSymLinks AllowOverride None Order allow,deny Allow from all </directory> <proxy balancer://mongrel_cluster> BalancerMember http://127.0.0.1:5000 BalancerMember http://127.0.0.1:5001 Allow from all </proxy> <Location /balancer-manager> SetHandler balancer-manager </Location> RewriteEngine On # Uncomment for rewrite debugging # RewriteLog "/var/log/apache2/ioi_rewrite.log" # RewriteLogLevel 9 # Redirect all non-static requests to cluster RewriteCond %{REQUEST_URI} ^/grader/(.*)$ RewriteCond /home/ioi/grader/web/public/%{REQUEST_FILENAME} !-f RewriteRule ^/grader/(.*)$ balancer://mongrel_cluster/grader/$1 [P,QSA,L]
Next, restart apache2.
/etc/init.d/apache2 restart
Edit routes.rb
cd ~/grader/web/config emacs routes.rb
Add the bolden text to the file:
ActionController::Routing::Routes.draw do |map| # The priority is based upon order of creation: first created -> highest priority. # Sample of regular route: # map.connect 'products/:id', :controller => 'catalog', :action => 'view' # Keep in mind you can assign values other than :controller and :action # Sample of named route: # map.purchase 'products/:id/purchase', :controller => 'catalog', :action => 'purchase' # This route can be invoked with purchase_url(:id => product.id) # You can have the root of your site routed by hooking up # -- just remember to delete public/index.html. map.connect 'grader/', :controller => 'main', :action => 'login' # Allow downloading Web Service WSDL as a file with an extension # instead of a file named 'wsdl' map.connect ':controller/service.wsdl', :action => 'wsdl' # Install the default route as the lowest priority. map.connect 'grader/:controller/:action/:id.:format' map.connect 'grader/:controller/:action/:id' end
Edit environments/production.rb
cd ~/grader/web/config/environments emacs production.rb
Set config.action_controller.asset_host to the URL of your grader site.
# Settings specified here will take precedence over those in config/environment.rb # The production environment is meant for finished, "live" apps. # Code is not reloaded between requests config.cache_classes = true # Use a different logger for distributed setups # config.logger = SyslogLogger.new # Full error reports are disabled and caching is turned on config.action_controller.consider_all_requests_local = false config.action_controller.perform_caching = true # Enable serving of images, stylesheets, and javascripts from an asset server config.action_controller.asset_host = "http://<your-host-name-or-ip-address>/grader" # Disable delivery errors, bad email addresses will be ignored # config.action_mailer.raise_delivery_errors = false
Make a Symbolic Link Hack
In order to make CCS work, we need to create a symbolic link ~/grader/web/public/grader to ~/grader/web/public.
cd ~/grader/web/public ln -s ~/grader/web/public grader
Restart mongrel_cluster
cd ~grader/web mongrel_rails cluster::restart
And this should do it!
