Installing Kaldin Online Exam Management Solution On Debian 7 (Wheezy - AMD64)

Kaldin is a java/tomcat based online assessment software to help instructors create online assessments. Visit this page for more details: http://www.kaldin.com/ The script presented in this tutorial will install Kaldin for you. I have successfully tested this script on Debian_7.0.0 amd64 netinst CD image. So Ubuntu_12.04 should also work fine but use at your own risk.

This script will perform the below steps automatically: 

(1) Install Oracle Java from ppa

(2) Install Apache2, MySQL-5.5, Tomcat7 from the debian stable sources

(3) Install webmin

(4) Set Apache as proxy for tomcat

At the end, you should see a kaldin installation page on http://your_server_ip/kaldin, proceed with filling all the required details, this will populate the MySQL DB and allows you to login.

Below workarounds are not explained: 

PHPMyadmin is useful when dealing with MySQL, and is also needed when editing certain entries in Kaldin DB – Namely email_settings.

Webmin is useful when dealing with any Linux servers, in this case, it is very useful in dealing Postfix.

How to use this script..?

cd /tmp/

vi  kaldin 

Copy & paste the below code (just copy the script and right click inside vi editor).

Change SERVER_FQDN, hit Esc then Shift+ZZ will save (you should be knowing how to use vi editor).

chmod +x kaldin 

./kaldin   ## This will start the installation, just follow the on-screen instructions
