502 Bad Gateway 通过套接字将 Nginx 连接到 Django
502 Bad Gateway connecting Nginx to django via socket
我正在尝试按照 http://uwsgi-docs.readthedocs.org/en/latest/tutorials/Django_and_nginx.html. I've gotten everything working down to http://uwsgi-docs.readthedocs.org/en/latest/tutorials/Django_and_nginx.html#running-the-django-application-with-uwsgi-and-nginx 上的教程进行操作。我正在使用亚马逊 EC2 上的 ubuntu 14.4 实例：
我的 django 项目叫做 tp。这是屏幕截图：
按照我所做的说明进行操作：

如何设置 wsgi.py 文件的路径？
编辑 1：这是我的 ini 文件：
# mysite_uwsgi.ini file
[uwsgi]
# Django-related settings
# the base directory (full path)
chdir = /home/ubuntu/tproxy/tp
# Django's wsgi file
module = uwsgi
# the virtualenv (full path)
home = /home/ubuntu/.virtualenvs/env1
wsgi-file = /home/ubuntu/tproxy/tp/tp/wsgi.py
# process-related settings
# master
master = true
# maximum number of worker processes
processes = 3
# the socket (use the full path to be safe
socket = /tmp/mysite.sock
# ... with appropriate permissions - may be needed
chmod-socket = 664
# clear environment on exit
vacuum = true
我运行:
(env1)ubuntu@ip-172-31-28-196:~$ uwsgi --ini /home/ubuntu/tproxy/tp/mysite_uwsgi.ini
但仍然出现 502 错误。

编辑 2：home 是 virtualenv 的目录吗？我设置：
home = /home/ubuntu/tproxy/
现在：
(env1)ubuntu@ip-172-31-28-196:~$ uwsgi --ini /home/ubuntu/tproxy/tp/mysite_uwsgi.ini

你把它放在你的 uwsgi ini 文件里。这是一个例子：
[uwsgi]
# Django-related settings
# the base directory (full path)
chdir = /var/www/virtualenv/project
# Django's wsgi file
module = uwsgi
# the virtualenv (full path)
home = /var/www/virtualenv/
wsgi-file = /var/www/virtualenv/project/projectsettings/wsgi.py
# process-related settings
# master
master = true
# maximum number of worker processes
processes = 10
# the socket (use the full path to be safe
socket = /tmp/mysite.sock
# ... with appropriate permissions - may be needed
chmod-socket = 664
# clear environment on exit
vacuum = true
这是我的 ini 文件减去我的项目路径。我自己安装时也 运行 遇到了同样的问题，但通过查看 google 上的其他配置能够找到合适的答案。
