RoboRumble/Host your own Roborumble server

This is an article describing how to host your own RoboRumble server. The article was originally posted by Pavel Savara on his blog here.

Host your own Roborumble server

There are several reasons why you might want to run your own Roborumble server. Maybe you would like to run small local contest at your school or workplace. Or maybe you are testing your new shiny robot. Or may you want to collect some battle data, like myself.

The current Roborumble server is created and maintained by Darkcanuck. Luckily he shares the RumbleServer sources via subversion. It is implemented in PHP and MySQL.

Because I'm not PHP+MySQL expert, easiest solution for me was to download ready-made LAMP virtual machine and configure it. I know you are busy ;-), so I published my virtual appliance, you could just start using it. You can download it and run it in VMWare Player. Password is robocode, you should change it as soon. Or you could follow the guide below.

Configure server

Once you have LAMP stack up and running you need few things:

• Install subversion client
• Get PHP sources
• Configure RumbleServer
• Turn on URL rewriting mod in Apache
• Configure MySQL database and grant permissions

The appliance has could be configured from web admin. You can access it on https://192.168.1.12/ where 192.168.1.12 is the IP address assigned to the virtual machine by your DHCP server. I will use 192.168.1.12 which was assigned to me in rest of the article.

Webmin -> Global configuration -> Configure Apache Modules -> rewrite: switch ON

phpMyAdmin

Create database->roborumble, Import script schema/schema.sql

Priviledges -> add new user ->

name -> rumbleuser

pass -> rumblepass

Database for user -> None

Global privileges -> Select+Update+Insert+Delete

On root shell do something like this:

apt-get install subversion
cd /var/www/
mkdir rumble
cd rumble
svn co http://darkcanuck.net/svn/rumbleserver/trunk/ .
chmod g+w templates_c/
chown :www-data templates_c/
cat > participants.txt
[paste participants.txt file and press Ctrl-D]
cd config
cp config.php-sample config.php

Participants

Are defined as list of robots and their .jar files. Big competition is driven by this file. We could simplify our own list like this. We host the file on the appliance in folder /var/www/. So create you own shortlist and update it there. Note there are starting and ending tags.

start c:\robocode\roborumble.bat

Purge data

If you need to purge the data from the roborumble database and start from scratch just delete rows using MyPhpAdmin.

delete from battle_results;
delete from game_pairings;
delete from bot_data;
delete from participants;
delete from upload_stats;
delete from upload_users;

Oh, and once you are done with your local competition, don't forget to redirect back to the official RoboRumble server and contribute your CPU power!
