Ubuntu Linux Server

I¹m thinking of hosting my Seaside app on Ubuntu Linux Server. This is a
GUI-less OS which raises a couple of questions...

1) I'm currently running a bit of Squeak code in a Workspace window to
enable file-serving (and to set the WAKom port to 9090). When I download the
image to Ubuntu Linux Desktop running on my server, the image "forgets" that
I'm running on port 9090 (and probably forgets about file-serving as well).

How do I run this code on Ubuntu Linux Server without a GUI?

2) I also have to run a simple Seaside program to setup my database for my
Seaside app on the server machine. Without a GUI, I don't see how I can get
around this.

Forgive these questions. Not only am I a Squeak newbie, I'm also a Linux
newbie...

Thanks,
Richard

There is a VNC client/server implemented in squeak: http://
www.squeaksource.com/RFB.html. Works very well.

Since we have lots of images running at the same time, to connect to  
an image, we start/stop VNC via HTTP on the selected image. Having a  
GUI can be very useful for debugging.

Cheers,
Adrian

It may come GUI-less, but it doesn't have to stay that way.

sudo apt-get install -y xorg
ssh -X server
squeak -vm-display-x11 squeak.image

(VNC is a lot faster, though.)

image should start the server when you start the image. You can
configure WAKom from the commandline, too. If you invoke your image
with

squeak -nodisplay squeak.image "" port 9090

you can control the port WAKom will use on startup. The "" is necessary
as squeak expects the first argument to be a startup script location.

You could also put your code into a startup script an invoke

squeak -nodisplay squeak.image startup.st

The startup.st could contain the code from your workspace.

Have a look at

Smalltalk addToStartUpList: aService

you can have look at WAKom what is needed to be a service which is
addable.

Have a look at WASystemConfiguration. You subclass it and can build
a configuration editor which you can add to your application. Then you
can see it in the configuration under /seaside/config. Sorry, for not
being more verbose.

Alternatively you could use a startup script as well.

I use something like this

configuration := (
   (WADispatcher default)
      entryPointAt: 'mywebapp'
   ) configuration.

" webapp database configuration "
configuration valueAt: #database put: 'dbname'.

and so on.

Hope this helps,

Norbert
