迁移到nginx/uWSGI时未找到django设置

Question

我一直在和Apache / Mod_wsgi这个组合斗争，最后决定放弃，重新从服务器的部分开始。

我已经设置好了Nginx，让它把请求转发到uwsgi。使用uwsgi协议其实挺简单的。

不过uwsgi一直很顽固，我试着看文档、教程，还在IRC上问过问题……

结果总是出现同样的错误，Django的wsgi模块找不到设置文件，但当我在控制台运行同样的代码时却没有任何错误。

我把所有相关的脚本都贴在下面——我觉得我可能漏掉了什么明显的东西，但我不知道是什么。

我在Ubuntu 11.10上运行，使用Upstart脚本来启动。

Upstart脚本

description "uWSGI starter"
start on (local-filesystems
and runlevel [2345])
stop on runlevel [016]
respawn
exec /usr/local/sbin/uwsgi \
--uid www-data \
--socket 127.0.0.1:5050 \
--master \
--logto /var/log/uwsgi_main.log \
--logdate \
--optimize 2 \
--processes 4 \
--harakiri 120 \
--vhost \
--no-site

Nginx服务器配置

sys.path[:0] = new_sys_path

os.environ['DJANGO_SETTINGS_MODULE'] = 'PROJECT.settings'
