Deploying 0.9

[Elver Loho]

Hiya!

Could someone please explain to me the process of deploying a
0.9a2-based TurboGears app on Apache? I tried the version over at

http://www.turbogears.org/docs/deployment/mod_python.html

but that doesn't work. It bombs out with something along the lines of:

Mod_python error: "PythonHandler mpcp"

Traceback (most recent call last):

File "/usr/lib/python2.4/site-packages/mod_python/apache.py", line
299, in HandlerDispatch
result = object(req)

File "/usr/lib/python2.4/site-packages/mpcp-1.3-py2.4.egg/mpcp.py",
line 34, in handler
setup(options)

File "/usr/lib/python2.4/site-packages/mpcp-1.3-py2.4.egg/mpcp.py",
line 18, in setup
mod = __import__(modname, globals(), locals(), [fname])

File "/var/www/project/project_start.py", line 30, in ?
cherrypy.server.start()

File "/usr/lib/python2.4/site-packages/CherryPy-2.2.0rc1-py2.4.egg/cherrypy/_cpserver.py",
line 64, in start
Engine.start(self)

File "/usr/lib/python2.4/site-packages/CherryPy-2.2.0rc1-py2.4.egg/cherrypy/_cpengine.py",
line 91, in start
autoreload.main(self._start, freq=freq)

File "/usr/lib/python2.4/site-packages/CherryPy-2.2.0rc1-py2.4.egg/cherrypy/lib/autoreload.py",
line 63, in main
sys.exit(restart_with_reloader())

SystemExit: 2

Or if I remove cherrypy.server.start() from the last line of the
project_start.py script (as described on the aforementioned page) then
it bombs out with:

Mod_python error: "PythonHandler mpcp"

Traceback (most recent call last):

File "/usr/lib/python2.4/site-packages/mod_python/apache.py", line
299, in HandlerDispatch
result = object(req)

File "/usr/lib/python2.4/site-packages/mpcp-1.3-py2.4.egg/mpcp.py",
line 18, in setup
mod = __import__(modname, globals(), locals(), [fname])

ImportError: No module named py

So, um, how do I deploy a TurboGears 0.9a2 app with mod_apache?

The app I'm trying to deploy works fine running via cherrypy on both
my development comp and on the server I'm trying to deploy it on.

Any ideas or pointers as to how to deploy 0.9a2 stuff with mod_python?

Or, well, if there's no way to deploy a 0.9a2 TurboGears app with
mod_python, then are there any other options for getting this working
on Apache?

I'm using mod_proxy with Apache... There's a recipe on the Wiki.

Thge mpcp script does not work (I believe) with 0.9a2. Check out
http://trac.turbogears.org/turbogears/wiki/ModPythonIntegration09 for
an example using modpython_gateway.py which I use on production.

Hope it helps,

That works, sort of, but Catwalk decided to stop working.

I get a 500 internal error and in the logfile:

What gives?
