Solved - Pi 3 manual install webapp issues

[timlegge]

No joy I am afraid. I even recreated the database on the off chance that something was corrupt.

Is there a way to increase the gunicorn debugging?

This seems vaguely familiar, like I may have run into a similar issue while building up the image. Our internal docs differ a little bit from the instructions on github.

sudo pip install gunicorn --upgrade
sudo ln -s /usr/local/bin/gunicorn /usr/bin/gunicorn
echo "nginx hold" | sudo dpkg --set-selections
echo "gunicorn hold" | sudo dpkg --set-selections

Did you do an apt-get upgrade after installing gunicorn? It may have updated the package to a version that doesn't support websockets. I'd try a 'sudo pip install gunicorn --upgrade' and recreate the link just to be sure.

As for debugging, you can uncomment the two lines in /etc/gunicorn.d/alarmdecoder and restart gunicorn.

We got our pi3 in the mail today, so we'll be looking at this and releasing a working image for pi3 soon.

Thanks, I am restarting from scratch so I will see how it goes.

Going through the installation again and it is possible that I forgot to install the alarmdecoder python package

That would do it, though the logs should have shown a failure to import...

[timlegge]

A clean install last night with the same results. It does not seem like I can get additional logs to see what error is occurring.

In the meantime, since you have ser2sock working you can use the AlarmDecoder Keypad Software on any PC/Mac/Linux computer to interface with the stream.

[timlegge]

Thanks. I realized only late last night that the key pad address was not enabled on my panel. After I enabled it the software keypad works and I can seND command via the keypad and via a telnet to Ser2sock.

I need to go back to see if that makes any difference to the Web app but I doubt it.

Hi

I found the issue by running gunicorn manually as follows:

sudo /usr/bin/python /usr/bin/gunicorn --pid /var/run/gunicorn/alarmdecoder.pid --name alarmdecoder --user pi --group dialout --log-file /var/log/gunicorn/alarmdecoder.log --worker-class=socketio.sgunicorn.GeventSocketIOWorker --timeout=120 --env=POLICY_SERVER=0 --workers=1 --log-level=debug --log-file=/tmp/alarmdecoder.log wsgi:application

This resulted in a error:

Code: Select all

A Google search revealed:

UnicodeError on Raspbian using Raspberry Pi B+ #815 - https://github.com/ajenti/ajenti/issues/815

Which caused me to do this:

export LANGUAGE=en_US.UTF-8
export LANG=en_US.UTF-8
export LC_ALL=en_US.UTF-8
sudo pip install -U gevent==1.1b4

sudo service gunicorn restart

Problem solved!!!
