使用Nginx和Django设置Unix Socket

Question

我正在尝试按照http://uwsgi-docs.readthedocs.org/en/latest/tutorials/Django_and_nginx.html上的教程进行操作。 我已经把所有工作都归结为http://uwsgi-docs.readthedocs.org/en/latest/tutorials/Django_and_nginx.html#using-unix-sockets-instead-of-ports 。 我正在亚马逊EC2上使用ubuntu 14.4实例：

Nginx配置文件以：

# 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http://pymotw.com/2/socket/uds.html，Permission denied - nginx和uwsgi socket以及https://serverfault.com/questions/124517/whats-the-difference-间UNIX的插座和TCP-IP套接字

看起来它们都以“///”开头如果我理解正确，路径只指向（在我的情况下）django项目的根目录，路径必须以“.sock”结尾。 这看起来是对的吗？

编辑：我已经制作了uwsgi配置文件，但我试图用--socket开关运行它：

Nginx配置文件现在以：

# 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)
} 

按照我的想法，我在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：

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：我评论了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

我试过了：

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

但又得到了502错误。

编辑4： - 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.

因此，每次退出uWSGI时，都会删除套接字。 也许我应该关闭真空选项，以便保留chmod设置？

我变了：

vacuum          = false

但...

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

所以chmod没有保留..

现在收到内部服务器错误：

2015/03/04 19:33:26 [crit] 1531#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"

Answer 1

将其更改为服务器unix:///tmp/mysite.sock; 然后在你创建的uwsgi ini文件中，在/tmp/创建unix套接字
