1 How to install MIRC-Zn on Ubuntu Linux

• Download the script

wget http://timphillips.net/mirc/install-MIRC-Zn.txt

• Make it executable

mv ./install-MIRC-Zn.txt ./install-MIRC-Zn
chmod 777 ./install-MIRC-Zn

• Run the script

./install-MIRC-Zn

• Point your browser to the machine you just installed it on and MIRC should be up and running.
• This script will also upgrade a previous "Tim Phillips" installation of MIRC-Zn so it can be used again when the RSNA code is updated.

2 What the script does

• Checks you're running it as root or using sudo.
• Stops the MIRC-Zn service if its running.
• Checks which chipset you're running.
• Enables the ubuntu partner repo (to get Oracle Java).
• Answers the Java installation questions in advance.
• Installs SunJava and a few other necessary applications.
• Downloads the appropriate JAI ImageIO files installs JAI ImageIO.
• Downloads the latest version of MIRC-Zn.
• Writes an upstart script (so that CTP/MIRC will be run as a service automatically).
• Installs RSNA MIRC.

2.1 The script itself (in case you don't trust the download)

#!/bin/bash

# Make sure only root can run our script
if $EUID -ne 0 ; then
echo "This script must be run as root or using sudo" 1>&2
exit 1
fi

# Stop MIRC-Zn if it is running
if [ -f /etc/init/MIRC-Zn.conf ]
then
if [[ $(stop -q MIRC-Zn 2>&1 | grep Unknown) ]]
then
echo 'MIRC-Zn service not currently running ...'
echo 'MIRC-Zn will be upgraded with the latest version from the RSNA site ...'

3 Choosing between Ubuntu Desktop and Ubuntu Server

• 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.
• Ubuntu Server
  • Makes more sense - MIRC is a web service after all.
  • Will be leaner and faster.
  • Can run on a headless server or virtual machine.
  • TurnkeyLinux is a very good Ubuntu install for this purpose.
