The Perfect SpamSnake - Ubuntu Jeos 10.04 - Nginx, uWSGI & Baruwa

[Drex56]

Hi All,

wondering if any of you can give me a hand as im slowly frying my brain with this. My problem is as follows, I have setup MailScanner no problems, works fine, its just the Nginx, uWsgi and baruwa combination that are giving me headaches. I know im not using the prescribed 10.10 but it wasn't an option and I quite like LTS. Basically I have setup as per the how-to (associated conf and ini files below) and all I get at the moment is:

uWSGI Error
wsgi application not found


/etc/uwsgi/uwsgi-python2.6/baruwa.ini:

[uwsgi]
socket = /var/run/uwsgi/uwsgi-python2.6/baruwa/socket
master = true
processes = 2
env = DJANGO_SETTINGS_MODULE=baruwa.settings
module = django.core.handlers.wsgi:WSGIHandler()

/etc/nginx/sites-available/baruwa.conf:

server {
listen 80;
server_name exam.example.com;
root /usr/share/pyshared/baruwa;
#main access log
access_log /var/log/nginx/access.log;
#main error log
error_log /var/log/nginx/error.log;
location /static {
root /usr/share/pyshared/baruwa/static/;
}
# static resources
location ~* ^.+\.(html|jpg|jpeg|gif|png|ico|css|zip|tgz|gz|rar |bz2|doc|xls|exe|pdf|ppt|txt|tar|mid|midi|wav|bmp| rtf|js)$
{
expires 30d;
break;
}
location / {
uwsgi_pass unix:///var/run/uwsgi/uwsgi-python2.6/baruwa/socket;
include uwsgi_params;
}
}

One thing that is obvious is the socket, before everyone shouts at once a
"ls /var/run/uwsgi/uwsgi-python2.6/baruwa" returns:

pid socket

Hence the change from 'baruwa.sock' to 'socket'.

Please let me know if there is anymore information you need or if you would like me to test anything.

Thanks Muchly,

Drex

Hey,

Try this in your baruwa.ini:
pythonpath = /usr/share/pyshared/baruwa/

Restart nginx and uwsgi.

Let me know if that worked.

Hi Rocky,

Thanks for the suggestion, unfortunately, still a no-go, I have noticed this, however, when I restart uwsgi:

# /etc/init.d/uwsgi-python2.6 restart
 * Restarting WSGI server(s) uwsgi-python2.6
                                    /etc/init.d/uwsgi-python2.6: 109: Bad substitution
                                    /etc/init.d/uwsgi-python2.6: 109: Bad substitution
                                    /etc/init.d/uwsgi-python2.6: 109: Bad substitution

Is this anything that I should be worrying about? related at all?

Anyway my

/etc/uwsgi/uwsgi-python2.6/baruwa.ini

now looks like this:

[uwsgi]
   socket = /var/run/uwsgi/uwsgi-python2.6/baruwa/socket
   master = true
   processes = 2
   env = DJANGO_SETTINGS_MODULE=baruwa.settings
   module = django.core.handlers.wsgi:WSGIHandler()
   pythonpath = /usr/share/pyshared/baruwa/

Oh regarding the above uwsgi-python error, my

/etc/init.d/uwsgi-python2.6

looks like this:

Change the socket back to baruwa.sock, try to restart and see what happens. I haven't seen that error and not sure why it's happening right now. I'll dig some more. Have you altered anything with uwsgi/nginx after the setup beside the ini and conf files?

[Drex56]

Hi Rocky,

Well changed baruwa.ini and baruwa.conf back to baruwa.sock and restart bout uWSGI and nginx (in that order) and now have a lovely "502 gateway" error.

This is the error I initailly cam across when I started everything up which led me to change the socket to "socket".

Other than that everything is set as per the guide.

Thanks for all your help thus far, I spent a long time trying to google the error before posting and couldn't find anything or relevance on it.

Thanks,

Drex

Does this folder exist in your setup?
/var/run/uwsgi/uwsgi-python2.6/baruwa/

Change the socket line to /tmp/baruwa.sock in your ini and conf file and see what happens.

What's in your uwsgi-python2.6 log file?
