Unable to run Django

Hi.

I'm trying to run Django through Cherokee 0.99.24-1~jaunty~ppa1 on
Ubuntu 9.04 server without success.

To be sure I'm not doing something silly, I've purged the system and
installed Cherokee from scratch. Then I've used the wizard to set up a
minimal Django site using defaults wherever I could.

The server starts without complaint, but serves only from the default
"fall through" handler, and there's no scgi processes started.

The config file below, minus icon- and mime-lines.

Any tips on how to troubleshoot this thing? I've already tried running
the interpreter line from a shell as the www-data user, and it seems
to work as there's six processes listed by ps aux | grep python
afterwards.

Re: Unable to run Django [In reply to]

Hi Leonel.

Yes, I used the wizard, and I do have Python-flup (1.0-1) installed.

Hi Nils,

not an expert on Django or Cherokee, but my setup is similar. I run my
local Django on Cherokee 0.99.24 from the PPA as well, on Ubuntu 9.04
Desktop.

For comparison, here is the Django-part from my cherokee.conf

vserver!20!rule!200!encoder!deflate = 0
vserver!20!rule!200!encoder!gzip = 0
vserver!20!rule!200!expiration = epoch
vserver!20!rule!200!handler = scgi
vserver!20!rule!200!handler!balancer = round_robin
vserver!20!rule!200!handler!balancer!source!1 = 2
vserver!20!rule!200!handler!change_user = 0
vserver!20!rule!200!handler!check_file = 0
vserver!20!rule!200!handler!error_handler = 1
vserver!20!rule!200!handler!pass_req_headers = 0
vserver!20!rule!200!handler!xsendfile = 0
vserver!20!rule!200!match = directory
vserver!20!rule!200!match!directory = /
vserver!20!rule!200!match!final = 1
vserver!20!rule!200!no_log = 0
vserver!20!rule!200!only_secure = 0

vserver!20!rule!100!handler = common
vserver!20!rule!100!match = default
vserver!20!rule!100!match!final = 1

The difference I see here to your setup is that you customized the
default handler to pass requests to Django. I left the default handler
and created an Directory handler for "/" to do that. Not sure if this is
important, though.

And here is the part that defines the Django information source:

source!2!host = 127.0.0.1:3033
source!2!interpreter =
/home/aguafuertes/geany-projects/attitude/manage.py runfcgi
method=threaded host=127.0.0.1 port=3033 protocol=scgi
source!2!nick = Django
source!2!type = interpreter

I'm really no expert here, but maybe the difference how the intepreter
is defined (socket vs. TCP port) gives you an idea what you can try. I
did not setup Django with the Wizard, btw.

Good luck
Gregor

Re: Unable to run Django [In reply to]

Hi Gregor.

Sorry for the personal email, Gmail unfortunately makes it really easy
to make that mistake...

Here it is again, with some additions.

Thanks, it's good to know it can be done.

> For comparison, here is the Django-part from my cherokee.conf

(snipped, but not forgotten...)

What is your document root set as? I've tried both /var/www and
/home/nils/mysite with no difference.

Rather, the wizard did. It added a new virtual server, but I think the
main difference with your setup may be the "match" bit. I added a new
target above the default scgi target, similar to yours, but with no
difference.

> And here is the part that defines the Django information source:

Thanks for the example, I will try to see if switching from pipes to
"tubes" will help. (It didn't.)

I'd prefer to fix the wizard setup though, if it's possible. That
could hopefully be useful for more than just me.

It seems to me the added virtual server, though above the default one,
is never called. There's nothing logged for that server ever, only for
the default one.

I'm stumped.

Nils

Re: Unable to run Django [In reply to]

I thought I had found it...

After reading this bug report:
https://bugs.launchpad.net/ubuntu/+source/cherokee/+bug/378772

I looked into /usr/bin for spawn-fcgi. It turns out this is a link to
/etc/alternatives/spawn-fcgi. However, that file does not exist.
There's however a binary file called spawn-fcgi.standalone in
/usr/bin. I linked to it (using sudo update-alternatives --set
spawn-fcgi /usr/bin/spawn-fcgi.standalone) but unfortunately, that did
not seem to help with my Cherokee+Django problem, I even rebooted the
server to be certain.

I also have it running un Ubuntu 8.04 server and just checked, the
Django setup is identical to my local one.

I use /home/aguafuertes/.../ - no special permissions set, as far as I
can tell.

Another thing I saw is that you prefixed the interpreter input in the
Django information source with "python" - mine looks just like this
"/home/aguafuertes/geany-projects/attitude/manage.py runfcgi
method=threaded host=127.0.0.1 port=3033 protocol=scgi"

Ok, that would also be an explanation ;) Can't really help you there,
but there should be enough experts on the list.

Good luck.

There is a spawn-fcgi in the cherokee PPA for jaunty
