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.
เนื้อหา
Install HAML
The grader makes use of HAML. So you need to install it first.
gem install haml --no-ri
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/tags/0.1 ~/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::config -e production -p 5000 -a 127.0.0.1 -N 2 -c ~/grader/web
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 make the grader application as one of the available sites.
cd /etc/apache2/sites-available sudo emacs grader
Paste the following snippet of code to the file grader just created.
<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 BalancerMember http://127.0.0.1:5002 BalancerMember http://127.0.0.1:5003 BalancerMember http://127.0.0.1:5004 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/$1 [P,QSA,L] </VirtualHost>
