Yep - this stumpped me also.

Got through the installation up on Amazon ok, had the instance running, and when I select to view the public DNS "example-host-1.amazonaws.com" in my browser I see the default drupal home page.  Yeah!

But how to get to phpMyAdmin and webmin pages?  Not so obvious to some of us less brilliant folks.  But with a little bit of reading I figured out, if you follow the installation documentation provided:

First, within SSH be sure to open the README to obtain the random password  (this is NOT the activation key).

Then you can visit the control pages at:

drupal : http://example-host-1.amazonaws.com

phpMyAdmin: https://example-host-1.amazonaws.com:12322/

using root & random_password

Webmin: https://example-host-1.amazonaws.com:12321/

again using root & random_password

Turnkey folk - good product but you might consider adding this bit-o-info to the docs.  :-)

Best regards,

Chris

Perhaps have a read over the documentation and elaborate as you see fit - its a wiki!

It doesn't seem that I have edit permissions. (even after signing in)

Sorry to lead you astray. I was under the impression that logged in users could edit all the wiki pages. It looks like that one's been locked. I guess you could start a new child page or ask Alon or Liraz (the Devs) to unlock it for you.
