AppScale install on Debian/Raspian.

[Leo Andres]

Has anyone succeeded in installing AppScale onto a Debian machine from source rather than on Ubuntu?

Hi Leo,

You can give this branch a try, which should allow you to build on Wheezy. We currently test only Precise and Trusty, so I wouldn't recommend using it in production, but I was able to build AppScale successfully in a Wheezy Vagrant box with that branch.

Hi Chris,

I got it to compile after pulling your code into mine.  However, I got the following error:

Message from sys...@localhost.localdomain at Feb 13 22:52:38 ...
 haproxy[4385]: proxy appscaledashboard has no server available!

Message from sys...@localhost.localdomain at Feb 13 22:52:41 ...
 haproxy[4443]: proxy appscaledashboard has no server available!

Any idea what that could mean?

Thanks,
Leo

Sorry, forgot to say that I got that error after running "appscale up"

The dashboard is the application sitting on port 1080 on each appscale
deployment. It is interesting you get the message on the shell, I have not
seen it before, but it seems to imply that the dashboard is not coming up
properly. Can you check first the controller logs, then the
app___appscaledashboard logs? Maybe also the appmanagerserver logs.

Just to clarify the order of events is:
- during the up phase, the controller sends the command to start the
dashboard (you should see this part in the controller logs);
- the appmanagerserver receives the order to start the dashboard (you
should this part on the AppManagerServer logs);
- the environment for the dashboard is created (you should see this part
in the app___appbashboard logs).

cheers

I think this error is due to the haproxy dashboard configuration being written and reloaded before the dashboard comes up. I see the error a few times in my syslog as well (not echoed to the shell, though) under normal operation on an appscale up.

Unless the error is persistent, I wouldn't worry about it. We're in the process of changing the order of events, which should silence that error. Even so, I don't think it indicates anything is broken except for the time it takes for the dashboard app to start.

Hi Chris,

Thanks for your help.  I went ahead and ignored those errors, and sure enough, the AppScale Dashboard came up.

Thanks,
Leo

Hi Leo,

Could u successfully deploy on debain based OS ??? Have u tried raspberry pi 3 that supports debain Jessie rather than wheezy?? 

Thanks
