Python Nginx和uWSGI的内部服务器错误

我正在尝试在Linode.com上使用Nginx托管一个应用程序，但是我在uWSGI配置上很早就被卡住了

我已经使用并成功部署了Nginx（在浏览器中收到Nginx欢迎消息）

虽然上面的教程是针对Ubuntu12.04的，但我已经使用了14.04

当我进入uWSGI配置和“Hello World”Python应用程序时，问题就开始了。在浏览器中转到

location/

返回

加载资源失败：服务器响应状态为500（内部服务器错误）

，并且在server Error.log中未记录任何内容<代码>位置/static工作，并且可以不挂起故障地为文件服务

我尝试了很多东西，并广泛地寻找谷歌和Stackoverflow的修复方案，但什么都没有，我现在有点沮丧

谢谢你的帮助

这里是我的配置文件（我已经隐藏了我的域和ip）：

我不明白它是什么/etc/nginx/sites enabled/dev.host.in？如何或为什么*.in？ 我想你应该试试

step 1.

create project.ini file

# django_project.ini file
[uwsgi]

# Django-related settings
# the base directory (full path)
chdir           = /home/username/django_project
# Django's wsgi file
module          = blog.wsgi
# the virtualenv (full path)
home            = /home/username/Env/project
# process-related settings
master          = true
pidfile         = /tmp/proj_uwsgi.pid
# maximum number of worker processes
processes       = 5
# the socket
socket          = :8001
# ... with appropriate permissions - may be needed
# chmod-socket    = 664
# clear environment on exit
vacuum           = true
# background the process
daemonize        = /home/username/django_project/error_uwsgi.log


step 2.

create mysite.conf in nginx, vim /etc/nginx/conf.d/mysite.conf

upstream django {
    #server unix:///home/username/django_project/djproj.sock; # for a file socket
    server 127.0.0.1:8001; # for a web port socket (we'll use this first)
}

# configuration of the server
server {
    # the port your site will be served on
    listen      80;
    # the domain name it will serve for
    server_name localhost mysite.com www.mysite.com; # 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/username/django_project/media;  # your Django project's media files - amend as required
    }

    location /static {        alias /home/username/django_project/static; # your Django project's static files - amend as required
    }

    # Finally, send all non-media requests to the Django server.
    location / {
        uwsgi_pass  127.0.0.1:8001;#project;        
        include     /home/username/django_project/uwsgi_params; # the uwsgi_params file you installed
    }
}



step 3.

ln -s /etc/nginx/uwsgi_params /home/username/django_project/

step 4.

uwsgi --ini django_project.ini

uwsgi --stop /tmp/proj_uwsgi.pid
uwsgi --reload /tmp/proj_uwsgi.pid

你的settings.py文件在哪里？我甚至没有进入Django安装程序。问题是，即使是我的hello world uWSGI应用程序也无法工作。

wsgi\u configuration\u module.py

。中的一个是印度域（回想起来，我可能应该将其更改为.com以避免混淆）。谢谢你的回答，我会很快尝试这个解决方案。
