This describes the creation of a custom Ubuntu Live CD, for the purpses of demoing a web service.

Ubuntu Page

This document requires that you follow this ubuntu page on the subject. I'm only mentioning a few specific gotchas here.

Free some disk space

I removed these:

  • Openoffice.org
  • Evolution
  • Gaim
  • Sample Docs
  • Ekiga
  • Gthumb

Set the repository

If your CD is going to have limited distribution, it might be a good idea to set a local ubuntu repository in /etc/apt/sources.list

Now is also a good time to dist-upgrade to the lastest security updates, backports, etc.

Set up some "server" services

  • Install nullmailer, apache2, php5, mysql, etc.
  • Set DO_NOT_START=0 in /etc/default/apache2
  • Set up any php settings you need in /etc/php5/apache2/php.ini
  • Set up mysql databases, and create a user with a random password (although this will be static across all CDs)
  • Install your webapp, and give it some sensible default settings.
  • Edit /etc/apache2/sites-available/default, and add EnableSendfile Off. Unionfs doesn't currently support sendfile(). This may change in the future...

Desktop settings

Build

Cleanup, build, and test, as the ubuntu documentation describes
