I am struggling to find a solution in seeting up the xqueue and ExternalGrader for my bitnami stack of Open edX.
I noticed a file "install_xqueue.sh" which contains some commands to install rabbitmq-server, python-mysqldb and Set up nginx proxy.
I followed those commands, got several errors, but I don't think that this is the case for a bitnami stack, since those servers are already installed.
Then I noticed another file "run.sh" with a command "gunicorn --workers=4 -b 127.0.0.1:3031 xqueue.wsgi &", which tries to start a server with no success.
Then, following the steps suggested here: https://groups.google.com/forum/#!msg/edx-code/-xMxjjg6uv8/nSHvkBn0HAAJ
and here: https://github.com/dagg/OpenEdxExternalGrader
In those threads they suggest to edit the file "/edx/app/xqueue/xqueue.env.json". in our bitnami stack there is a folder xqueue in the apps/edx/edx-platform folder, but there is no xqueue.env.json file.
Initially I created that file, but it did not work. Probably sth needs to be changed in the following lines or I didn't understand clearly the concept behind xqueue.
Could you please help me in this? Has anyone worked successfully with externalGrader and xqueue?
Many thanks in advance,
