== How to install MIRC-Zn on Ubuntu Linux ==
+
This is a small part of what the MIRC-Zn installation on Linux script will do automatically for you
* 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.
+
  
==What the script does==
+
=== Using an UpStart Script ===
 +
Ubuntu and many other Linux distros use UpStart to run services.
 +
The below example assumes CTP is installed at
  
* Checks you're running it as root or using sudo.
+
/usr/share/CTP/
* 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.
+
  
===The script itself (in case you don't trust the download)===
+
You can modify it to suit a different locations.

==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.
 
** [http://turnkeylinux.org TurnkeyLinux] is a very good Ubuntu install for this purpose.

This is a small part of what the MIRC-Zn installation on Linux script will do automatically for you

Using an UpStart Script

Ubuntu and many other Linux distros use UpStart to run services. The below example assumes CTP is installed at

/usr/share/CTP/

You can modify it to suit a different locations.

Cut and paste the below code into a file named

/etc/init/MIRC-Zn.conf

The code

description "MIRC Zn (CTP plugin not Tomcat)"
author "Tim Phillips <timothy.john.phillips@gmail.com>"

start on (local-filesystems and net-device-up IFACE!=lo)
stop on stopping network-services

respawn

expect fork

script
cd /usr/share/CTP/
java -jar ./CTP-runner.jar
end script
Any questions or comments please email me at timothy.john.phillips@gmail.com - Tim Phillips.
