Running CTP as a Linux Service
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
- The script below will talk you through it.
- 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:
- Check which chipset you're running
- Enable 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 and fixes the inherent problem in the Linux release
- 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
- If you are logged in without X11 or X-forwarding this script will tell you and help you fix it.
- Lightweight installations of Ubutnu (eg jeos or TurnkeyLinux core) don't have the libraries for X-forwarding. This script will install them.
