Running CTP as a Linux Service

This is most easily done using Ubuntu If you are using virtual machines I recommend [http://turnkeylinux

1 Instructions for installing the latest CTP/MIRC-Zn in Ubuntu

1.1 Desktop or Server?

• Ubuntu Server
  • Makes more sense - MIRC is a web service after all
  • Will be leaner and faster
  • You will need to ssh in to the server with X-fowarding when you run the MIRC-Installer.jar file
    • From a linux desktop to a linux server this is ssh -x username@host
    • From a mac to a linux server this is ssh -Y username@host
    • From a windows box you will need Putty and Xming X Server for MS Windows (google them).
• Ubuntu Desktop
  • Easier (very easy) if you're new to Linux
  • May be very slightly slower but on modern hardware you are unlikely to notice the difference.
  • You can just do part 1 and then part 2 straight away (X-forwarding is not an issue).

1.2 The script

You can cut and paste each line to the command prompt or just put the whole thing into a file and execute it. This script does the following things:

1. Check which chipset you're running
2. Enable the ubuntu partner repo (to get Oracle Java)
3. Answers the Java installation questions in advance
4. Installs SunJava and a few other necessary applications
5. Downloads the appropriate JAI ImageIO and fixes the inherent problem in the Linux release
6. Installs JAI ImageIO
7. Downloads the latest version of MIRC-Zn
8. Writes an upstart script (so that CTP/MIRC will be run as a service automatically)

#!/bin/bash

#check which chipset we're using
