问题描述
［补充］关于uwsgi_params：官网上面是这么说的：
Configure nginx for your siteYou will need the uwsgi_params file, which is available in the nginx directory of the uWSGI distribution, or from https://github.com/nginx/nginx/blob/master/conf/uwsgi_params Copy it into your project directory. In a moment we will tell nginx to refer to it.
［原文］按照这个文档http://uwsgi-docs.readthedocs.org/en/latest/tutorials/Django_and_nginx.html部署uwsgi＋nginx＋django的时候，uwsgi和django或纯python配合都能出正确结果，安装了nginx之后也能在浏览器刷新看到Welcome to nginx!。
然后我把nginx配置文件建立在django项目文件夹下面了：
# mysite_nginx.conf# the upstream component nginx needs to connect toupstream django { # server unix:///path/to/your/mysite/mysite.sock; # for a file socket server 127.0.0.1:8001; # for a web port socket (we’ll use this first)}# configuration of the serverserver { # the port your site will be served on listen 8000; # the domain name it will serve for server_name 192.168.33.10; # substitute your machine’s IP address or FQDN charset utf-8; # max upload size client_max_body_size 75M; # adjust to taste # Django media location /media {alias /home/vagrant/mysite/mysite/media; # your Django project’s media files - amend as required } location /static {alias /home/vagrant/mysite/mysite/static; # your Django project’s static files - amend as required } # Finally, send all non-media requests to the Django server. location / {uwsgi_pass django;include /home/vagrant/mysite/mysite/uwsgi_params; # the uwsgi_params file you installed }}
但无论是试图直接用test.py输出hello world，还是启动django服务器，都仍然只能看到Welcome to nginx!，服务器ip后面带上路径也是只有这个。
直接用test.py的时候输出如下：
$ uwsgi --socket :8001 --wsgi-file test.py *** Starting uWSGI 2.0.9 (64bit) on [Mon Feb 2 15:54:01 2015] ***compiled with version: 4.6.3 on 02 February 2015 09:51:05os: Linux-3.2.0-23-generic #36-Ubuntu SMP Tue Apr 10 20:39:51 UTC 2012nodename: precise64machine: x86_64clock source: unixdetected number of CPU cores: 2current working directory: /home/vagrant/mysite/mysitedetected binary path: /home/vagrant/mysite/bin/uwsgi!!! no internal routing support, rebuild with pcre support !!!*** WARNING: you are running uWSGI without its master process manager ***your processes number limit is 2782your memory page size is 4096 bytesdetected max file descriptor number: 1024lock engine: pthread robust mutexesthunder lock: disabled (you can enable it with --thunder-lock)uwsgi socket 0 bound to TCP address :8001 fd 3Python version: 2.7.3 (default, Dec 18 2014, 19:25:50) [GCC 4.6.3]*** Python threads support is disabled.

问题解答
回答1：问题解决了。其实是因为/etc/nginx/sites-enabled/下面有两个配置文件：default和我自己配置的mysite_nginx.conf，nginx默认使用了default。删掉default就对了。
回答2：配置文件没有起作用，检查是否正确读取了 nginx的配置文件，先用个最简单的demo测试是否配置文件按是否生效
回答3：Nginx 配置的是8000端口，你需要访问nginx 的8000端口，
你的nginx django配置的是
upstream django {# server unix:///path/to/your/mysite/mysite.sock; # for a file socketserver 127.0.0.1:8001; # for a web port socket (we’ll use this first)}
所以启动django应该以8001端口为基准。
uwsgi_params 是在nginx里面。配置路径错误。 uwsgi_params 在 /etc/nginx/uwsgi_params.
回答4：接口冲突了，首先每个服务只监听1个接口，按照配置文件的理解应该是，nginx:8000 django:8001在这种情况下执行python manage.py runserver localhost:8000 没有报错，说明nginx配置文件没有起作用。可能使用的还是默认的80端口启动的，请检查接口列表，linux命令为：netstat -natp | grep nginx如过想使用自定义的配置文件启动,请nginx -h查看具体命令 大概是-p 或者-c.在正确配置启动nginx情况下，启动django也应该是使用python manage.py runserver localhost:8001 保证与配置文件设计相符
回答5：你访问的时候带上端口号了吗？ http://192.168.33.10:8000
回答6：确认下配置文件指向是否正确，例如
/usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf回答7：
首先，记得带端口号。
其次，报错说明你配置错了。看错误日志吧。
