Python 使用Nginx和Django设置Unix套接字

我正在努力按照教程的内容学习。我已经把一切都安排好了。我正在amazon EC2上使用ubuntu 14.4实例：

Nginx配置文件以以下内容开头：

# the upstream component nginx needs to connect to
upstream 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)
} 

我对设置unix套接字的语法感到困惑。我查看了几个来源，包括，和

如果我理解正确，它们看起来都以“//”开头，路径只指向（在我的例子中）django项目的根目录，路径必须以“.sock”结尾。这看起来对吗

编辑：我已经创建了uwsgi配置文件，但是我尝试使用--socket开关来运行它：

Nginx配置文件现在以以下内容开始：

# the upstream component nginx needs to connect to
upstream django {
 server unix:///tmp/mysite.sock; # for a file socket
# server 127.0.0.1:8001; # for a web port socket (we'll use this first)
} 

按照我想你说的，我正在socket/tmp/mysite.sock上运行uwsgi

(env1)ubuntu@ip-172-31-28-196:~$ uwsgi --socket /tmp/mysite.sock --wsgi-file test.py --chmod-socket=664

当我打开时：

http://52.10.----:8000/

在firefox中，我看到：

502 Bad Gateway

nginx的错误日志显示：

2015/03/04 15:08:44 [crit] 18398#0: *3 connect() to unix:///home/ubuntu/mysite.sock failed (13: Permission denied) while connecting to upstream, client: 64.56.60.130, server: 52.10.200.38, request: "GET / HTTP/1.1", upstream: "uwsgi://unix:///home/ubuntu/mysite.sock:", host: "52.10.200.38:8000"

编辑2：我注释掉了django相关的东西-

 # mysite_uwsgi.ini file
 [uwsgi]    

 # Django-related settings
 # the base directory (full path)
 #chdir           = /path/to/your/project
 # Django's wsgi file
 #module          = project.wsgi
 # the virtualenv (full path)
 #home            = /path/to/virtualenv     

 # process-related settings
 # master
 master          = true
 # maximum number of worker processes
 processes       = 1
 # 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

我试过：

(env1)ubuntu@ip-172-31-28-196:~$ uwsgi --ini /home/ubuntu/tproxy/tp/mysite_uwsgi.ini --wsgi-file test.py

但又出现了502错误

2015/03/04 17:50:00 [crit] 18842#0: *1 connect() to unix:///tmp/mysite.sock failed (13: Permission denied) while connecting to upstream, client: 64.56.60.130, server: 52.10.200.38, request: "GET / HTTP/1.1", upstream: "uwsgi://unix:///tmp/mysite.sock:", host: "52.10.200.38:8000"

编辑4:-刚刚注意到

♥SIGINT/SIGQUIT received...killing workers...
worker 1 buried after 1 seconds
goodbye to uWSGI.
VACUUM: unix socket /tmp/mysite.sock removed.

所以每次我退出uWSGI，插座都会被移除。也许我应该关闭真空选项以便保留chmod设置

我改变了：

vacuum          = false

但是

 (env1)ubuntu@ip-172-31-28-196:/tmp$ sudo chmod 777 mysite.sock
 (env1)ubuntu@ip-172-31-28-196:/tmp$ ls -la

现在获取内部服务器错误：

---

将其更改为“服务器<代码>unix:///tmp/mysite.sock;然后在您创建的uwsgi ini文件中，在

/tmp/

中创建unix套接字感谢您查看这个人，我已经按照您的建议更改了nginx配置。至于uwsgi配置，我想你说的是什么？如果是这样的话，你把这个文件放在哪里，我不认为它在图坦卡蒙的什么地方。我通常只是把它和settings.py和wsgi.py文件放在同一个文件夹中。稍后，当您设置皇帝时，您将看到原因。没问题，昨晚我在AmazonEC2上再次设置了相同的设置以进行尝试，效果非常好。：）仔细检查您的配置，确保您将.sock放在nginx正在查找它的同一位置。启动它时uwsgi会说什么吗？好的，我找到了答案，我从错误的目录运行了uwsgi--ini/home/ubuntu/tproxy/tp/mysite\u uwsgi file test.py--chmod socket=777，但test.py不在那里
