问题描述
环境：OS X 10.8.5django 1.6python 2.7.2先贴一下我的配置
[uwsgi]# socket = /Users/scarlex/Projects/venv/mysite/white.socksocket = 127.0.0.1:3031chdir = /Users/scarlex/Projects/venv/mysite/module = sakuramai.wsgi:applicationhome = /Users/scarlex/Projects/venvenv = DJANGO_SETTINGS_MODULE=sakuramai.settingsstatic_files = falsemaster = trueprocesses = 5chmod-socket = 664vacuum = truestats = 127.0.0.1:9191
upstream white { server localhost:3031; # server unix:///Users/scarlex/Projects/venv/mysite/white.sock;}server { listen 80; server_name mysite.com localhost; charset utf-8; location /static/ {alias /Users/scarlex/Projects/venv/mysite/static/expires 30d; } location / {uwsgi_pass white;include uwsgi_params;uwsgi_param UWSGI_SCRIPT django_wsgi; }}
配置基本都是按照下面这两个教程来的https://uwsgi-docs.readthedocs.org/en/latest/tutorials/Django_and_nginx.htmlhttps://docs.djangoproject.com/en/1.6/howto/deployment/wsgi/uwsgi/
如果用 nginx 和 uwsgi 都用 socket 的话，会报 502 错误，uwsgi里面一直都是下面这样，看不到有请求到来。
*** uWSGI is running in multiple interpreter mode ***spawned uWSGI master process (pid: 88475)spawned uWSGI worker 1 (pid: 88476, cores: 1)spawned uWSGI worker 2 (pid: 88477, cores: 1)spawned uWSGI worker 3 (pid: 88478, cores: 1)spawned uWSGI worker 4 (pid: 88479, cores: 1)spawned uWSGI worker 5 (pid: 88480, cores: 1)*** Stats server enabled on 127.0.0.1:9191 fd: 17 ***
如果都用 127.0.0.1:3031 的话，都会报 400 错误。但是 uwsgi 里面可以看到有请求到来。

烦了两天了，不知道应该怎么解决...
另外想问一下 nginx 中的 include uwsgi_params; 作用是什么？我发现如果没有这个的话，uwsgi就会报下面的错误：
Traceback (most recent call last): File '/Users/scarlex/Projects/Python-projects/skm2014/lib/python2.7/site-packages/django/core/handlers/wsgi.py', line 196, in __call__ request = self.request_class(environ) File '/Users/scarlex/Projects/Python-projects/skm2014/lib/python2.7/site-packages/django/core/handlers/wsgi.py', line 91, in __init__ self.method = environ[’REQUEST_METHOD’].upper()KeyError: u’REQUEST_METHOD’
问题解答
回答1：如果用 nginx 和 uwsgi 都用 socket 的话，会报 502 错误
nginx报502,表示upstream设置有误或者upstream指向的server报错。unix:///Users/scarlex/Projects/venv/mysite/white.sock写法错误，多了两个斜杠，正确的是unix:/Users/scarlex/Projects/venv/mysite/white.sock。从题主贴出的uwsgi配置来看，chmod-socket = 664可能不当，尝试设为chmod-socket = 666。nginx一般是以http用户启动的，664可能无权限写入white.sock。
如果都用 127.0.0.1:3031 的话，都会报 400 错误。
这就跟nginx无关了，纯粹是uwsgi的配置或者django配置有误（如果是自身的脚本源码出错应该报5xx）。如果可能贴出django的settings.py吧。
提供一个可能性的猜测：
Finally, if DEBUG is False, you also need to properly set the ALLOWED_HOSTS setting. Failing to do so will result in all requests being returned as “Bad Request (400)”
