If you want a guaranteed way to hose your Web server, install Ensim. In a nutshell, Ensim is a control panel application that completely takes over your Web server and turns it into an appliance that any neophyte can manage themselves. The base operating system more or less gets pushed into the background, Ensim installs its own customized set of applications, and you never have to touch the command line again.
That’s all well and good for someone who wants Web Server in a Box functionality, but no good for a geek who wants full control over their system. If you ever want Ensim to die a horrible death, simply install some vendor security patches. Everything breaks horribly.
