nginx bad gateway - odd

Postby lando.wark » Tue Nov 15, 2016 1:16 am

I'm having an odd problem with omero web. I wanted to install on a Ubuntu 14.04 virtualbox using my username for development purposes. I had already installed on a 14.04 server and I used the same procedure, but with the virtualbox 'omero web start' says:

Starting OMERO.web... [OK]

But 'omero web status' says:

OMERO.web status... [NOT STARTED]

And when I go to the nginx page I get "502 - Bad Gateway". The Insight clients work fine.
If I set omero.web.application_server.host=0.0.0.0 and run the dev server to connect to port 4080 everything works fine.
The weird part is if I run "gunicorn --bind 127.0.0.1:4080 omeroweb.wsgi:application" I get a python traceback:

Traceback (most recent call last):
File "/usr/local/lib/python2.7/dist-packages/gunicorn/arbiter.py", line 557, in spawn_worker
worker.init_process()
File "/usr/local/lib/python2.7/dist-packages/gunicorn/workers/base.py", line 126, in init_process
self.load_wsgi()
File "/usr/local/lib/python2.7/dist-packages/gunicorn/workers/base.py", line 136, in load_wsgi
self.wsgi = self.app.wsgi()
File "/usr/local/lib/python2.7/dist-packages/gunicorn/app/base.py", line 67, in wsgi
self.callable = self.load()
File "/usr/local/lib/python2.7/dist-packages/gunicorn/app/wsgiapp.py", line 65, in load
return self.load_wsgiapp()
File "/usr/local/lib/python2.7/dist-packages/gunicorn/app/wsgiapp.py", line 52, in load_wsgiapp
return util.import_app(self.app_uri)
File "/usr/local/lib/python2.7/dist-packages/gunicorn/util.py", line 357, in import_app
__import__(module)
ImportError: No module named omeroweb.wsgi

Until I run "export PYTHONPATH=/home/omero/OMERO.server/lib/python:$PYTHONPATH". Then the error disappears, gunicorn runs and I can reach the web interface through nginx. The thing is I don't have any folder /home/omero.

I'm fine using the dev server here (It's what I was planning on using this install for), but I'd like to better understand what's going on here so I can better administer Omero.
Any thoughts?

which procedure? could you point me to the link?

which gunicorn version did you installed? what

pip freeze
says?

that is expected. to run gunicorn by hand you have to export
Code: Select all
export PYTHONPATH=/home/$USER/OMERO.server/lib/python:/home/$USER/OMERO.server/lib/python/omeroweb:$PYTHONPATH

Something doesnt' looks right here ;-) what
Code: Select all
sudo ls -al /home/omero
says?

Also could you check if pid in /home/$USER/OMERO.server/var/django_pid is the same as in ps -ef | grep gunicorn
