Omero Web mod_python on osx 10.6
Posted: Mon Sep 20, 2010 9:53 amHI
I have a fresh installation of snow leopard and have been following the pdf guide for dependency installations provided by Janek Claus and Kenneth Arcieri from NIH. I then followed the server installation instruction for UNIX systems on the omero website. I was able to get the web interface of omero running using the build in django web server started under the newly created system user omero. I am able to login and use the system.
But since this is suppose to be a production system I would very much prefer the mod_python/apache approach:
1. I have installed and enabled mod_pyhton in /etc/apache/httpd.conf:
LoadModule python_module /usr/libexec/apache2/mod_python.so
2. I have installed the Omero app in /Library/Omero
3. I have created and made belong to new system user omero the data dir /OMERO
4. I have added the following to the ~/.profile of the new omero user:
export PATH=/Library/Ice/3.3/bin:$PATH
export PATH=/Library/PostgreSQL/8.4/bin:$PATH
export PYTHONPATH=/Library/Ice/3.3/python:$PYTHONPATH
export OMERO_TEMPDIR=/var/lib/omero/tmp
5. I have added the following location definition to /etc/apache/httpd.conf
<Location "/">
SetHandler python-program
PythonHandler django.core.handlers.modpython
SetEnv DJANGO_SETTINGS_MODULE omeroweb.settings
PythonDebug On
PythonPath "['/Library/Omero/lib/python', '/Library/Omero/var/lib', '/Library/Omero/lib/python/omeroweb'] + sys.path"
</Location>
6. When I navigate to http://localhost/webadmin I get the following error:
MOD_PYTHON ERROR
ProcessId: 506
Interpreter: 'kentridge.local'
ServerName: 'kentridge.local'
DocumentRoot: '/Library/WebServer/Documents'

raise ImportError, "Could not import settings '%s' (Is it on sys.path? Does it have syntax errors?): %s" % (self.SETTINGS_MODULE, e)
ImportError: Could not import settings 'omeroweb.settings' (Is it on sys.path? Does it have syntax errors?): No module named Ice
So it seems that the webserver does not know where to find the Ice python module, isn't it? I specifically set this in ~/.profile when starting the internal django server as system user omero. How can I let apache know about the Ice location on my system?
Any help would be greatly appreciated.
