19 Nov 08 Installing Webmin / Virtualmin on Slicehost Ubuntu 8.04">Installing Webmin / Virtualmin on Slicehost Ubuntu 8.04

After trying out various web control panels, I finally settled on webmin.

I was looking for an open source / free web control panel that would allow users easily set up websites via virtual hosts and ftp accounts

Here are the steps to get it up and running quickly. This has to be done on a fresh new slice and not one that is already hosting other websites.

This assumes you have created a Ubuntu 8.04 slice
Set it up as per instructions here:
http://articles.slicehost.com/2008/4/25/ubuntu-hardy-setup-page-1
http://articles.slicehost.com/2008/4/25/ubuntu-hardy-setup-page-2
The fastest way to set up Virtualmin using the install script:
http://www.webmin.com/vinstall.html

$ wget http://software.virtualmin.com/gpl/scripts/install.sh
$ chmod +x install.sh
$ sudo ./install.sh

That’s all! You’ll be able to view your site via https://xxx.xxx.xxx.xxx:10000
I’ve managed to set it up with rails too following the instructions here:

23 Sep 08 Restful_authentication Internet explorer cannot logout http_basic problem">Restful_authentication Internet explorer cannot logout http_basic problem

If you’re getting a security box popup like I did, here’s the link to the solution

http://groups.google.com/group/rubyonrails-talk/browse_thread/thread/97981fedc00d98fa/3e435bd3e66952c7?lnk=raot

Basically, just edit /lib/authenticated_system.rb, and add ‘(:xml, :json)’

def access_denied
      respond_to do |format|
        format.html do
          store_location
          redirect_to new_session_path
        end
      format.any(:xml, :json) do
          request_http_basic_authentication ‘Web Password’
        end
      end
    end

Make sure your <head> tag has this too:
