迁移到nginx的/ uWSGI/Django的设置，没有发现

一直有一个Apache/mod_wsgi的堆栈持续存在的问题，最后决定把我的损失，并开始对事物迁移到nginx的/ uWSGI/Django的设置，没有发现

服务器端鲜有得到的Nginx设置代理请求到uwsgi。使用uwsgi协议相当容易。

不过uwsgi已经平原固执，试图读取文档/教程/要求在IRC ...... 请让Django的WSGI模块的同样的错误，没有找到设置，但是当我通过一个控制台我运行相同的代码不要有任何错误。

粘贴下面的所有相关脚本 - 假设我错过了一些明显的东西，但我不知道是什么。

在Ubuntu上运行11.10瓦特/新贵脚本启动

新贵脚本

在这个问题上的看法2500+和2名总票数？ – Alvin

首先你并不需要所有这些SYS的。路径一塌糊涂，你的nginx vars已经为你设置了virtualenv。

我建议你进入静态模式，因为动态虚拟主机模式非常复杂，往往很难调试。简单地改变你的命令行，然后删除从nginx的三个uwsgi_param项：

/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 
--virtualenv /home/USER/virtualenv/ 
--pythonpath /home/USER/virtualenv/ 
--chdir /home/USER/virtualenv/PROJECT 
--env DJANGO_SETTINGS_MODULE=PROJECT.settings 
--module "django.core.handlers.wsgi:WSGIHandler()"

应该足够（显然，你可以扔掉WSGI脚本）

这种方法得到了uwsgi启动，虽然现在我得到一个错误“无法加载应用程序的加载点= - 没有应用程序加载完全动态模式 - 尽管进展 - 谢谢 – Alvin

这种方法正常工作，一旦我审查它的拼写错误 - ** django.core.handlers.wsgi：WSGIHandler（）**（是WSHIHandler） – Alvin

我的猜测是你运行在python的virtualenv Django的应用程序。如果是这样，你需要在新贵脚本激活的virtualenv还有： exect /路径/到/的virtualenv /激活& &在/ usr/local/sbin中/ uwsgi

是的，我在virtualenv运行 - 没有这没有通过Upstart或控制台工作...感谢思想虽然 – Alvin
