Running CTP as a Linux Service

From MircWiki
Jump to navigation Jump to search

1 Choice: Ubuntu Desktop or Server?

  • 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.
  • 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).

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

2.1 (If you're new to Linux) How to cut and paste the script below into a file and execute it

  • Open an editor
nano ./
  • Cut and paste the code from the big box at the bottom of the page
  • Save the file and exit
ctrl-O and then hit enter
  • Make it executable
chmod 777 ./
  • Run it

2.2 What the script does

  • 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 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 have x-forwarding or are installing from Ubuntu Desktop ignore the below points
    • If you are logged in without X11 or X-forwarding this script will tell you and help you fix it.
    • By the time it gets to the part that needs X-forwarding it has installed the necessary libraries
    • You will need to exit and re login (ssh) in to the server with X-fowarding and 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).
