Provo ad aumentare il webserver per django su nginx + uwsgi, os - debian (3.1.0-1-amd64 x86_64) nginx 1.1.8-1, uwsgi 0.9. 8.3-1 configurazione:uWSGI + nginx per progetto django, errore con stringhe uwsgi
<uwsgi>
<socket>/tmp/uwsgi.sock</socket>
<process>1</process>
<master/>
<enable-threads/>
<uid>33</uid>
<gid>33</gid>
<pidfile>/tmp/uwsgi.pid</pidfile>
</uwsgi>
nel file di configurazione di /etc/uwsgi/apps-enabled/webapp.xml nginx
location/{
uwsgi_pass unix:///tmp/uwsgi.sock;
include uwsgi_params;
uwsgi_param UWSGI_SCRIPT webapp;
uwsgi_param UWSGI_CHDIR /data/web/webapp/webapp;
}
tutto projet in/data/web/webapp/webapp /, qui setting.py, urls ect. in /data/web/webapp/webapp/webapp.py
import sys, os
import django.core.handlers.wsgi
sys.path.insert(0, '/data/web/webapp/webapp')
os.environ['DJANGO_SETTINGS_MODULE'] = 'settings'
application = django.core.handlers.wsgi.WSGIHandler()
uid e gid 33 è facile da www-data try gestita uwsgi come
root#uwsgi -s /var/run/uwsgi.sock -x /etc/uwsgi/apps-enabled/webapp.xml
[uWSGI] parsing config file /etc/uwsgi/apps-enabled/webapp.xml

writing pidfile to /tmp/uwsgi.pid

setgid() to 33
setuid() to 33

bind(): Address already in use [socket.c line 70]
come il permesso che vogliono ? e qual è il problema .. se corro uwsgi come errore di radice è andato, e vedo

ma quando provo ad accedere al server, ngix restituisce 502 pagina di errore. E ancora: errore di autorizzazione in ceppi nginx:
2011/12/14 21:57:17 [crit] 20739#0: *1 connect() to unix:///tmp/uwsgi.sock failed (13: Permission denied) while connecting to upstream, client: 10.10.3.111, server: ******, request: "GET /favicon.ico HTTP/1.1", upstream: "uwsgi://unix:///tmp/uwsgi.sock:", host: "****.****.**"
se il cambiamento proprietario di /tmp/uwsgi.sock a nginix utente in fase di esecuzione (www-data), ha scritto altri registri
[error] 20739#0: *21 upstream prematurely closed connection while reading response header from upstream,
ma ancora errore 502 (
come risolvere questo problema? qualcuno mi può aiutare .. di voler utilizzare nginx + uwsgi invece di Apache. grazie
tuttavia, la soluzione è vicina :) Io uso il socket tcp ora e altro, cambio la configurazione di uwsgi e ho installato alcuni pacchetti in più. era un'opzione importante --autoload. ora uwsgi ha configurazione come questa:
<uwsgi>
<module>webapp</module>
<socket>127.0.0.1:5080</socket>
<pythonpath>/data/web/webapp/webapp</pythonpath>
<autoload/>
<daemonize>/var/log/uwsgi_webapp.log</daemonize>
<processes>1</processes>
<uid>33</uid>
<gid>33</gid>
<enable-threads/>
<master/>
<harakiri>120</harakiri>
<max-requests>5000</max-requests>
</uwsgi>
rimane per risolvere altri problemi .. uwsgi utilizzano non principale versione del sistema Python> _ <
option "pythonpath" found in plugin python26_plugin.so

lui usare Python 2.6.7, ma la versione del sistema principale è 2.7.2 e tutti i moduli python installati per questo, quindi molti errori nel registro - ripetuti tentativi di importare inesistenti, uno dei tanti errori tipici:
File "/usr/lib/python2.6/dist-packages/django/db/__init__.py", line 78, in <module>
connection = connections[DEFAULT_DB_ALIAS]
File "/usr/lib/python2.6/dist-packages/django/db/utils.py", line 93, in __getitem__
backend = load_backend(db['ENGINE'])
File "/usr/lib/python2.6/dist-packages/django/db/utils.py", line 51, in load_backend
raise ImproperlyConfigured(error_msg)
django.core.exceptions.ImproperlyConfigured: 'django_mongodb_engine' isn't an available database backend.
Try using django.db.backends.XXX, where XXX is one of:
'dummy', 'mysql', 'oracle', 'postgresql', 'postgresql_psycopg2', 'sqlite3'
Error was: No module named django_mongodb_engine.base
quindi .. come impostare la versione di python per uwsgi?
Oh .... mi dispiace. problema risolto: - [uwsgi_python27 -x/etc/uwsgi/apps-enabled/conf e tutto ok! grazie a tutti –
