Настройка Unix Socket с Nginx и Django

Question

Я пытаюсь следовать руководству по адресу http://uwsgi-docs.readthedocs.org/en/latest/tutorials/Django_and_nginx.html. У меня все работает до http://uwsgi-docs.readthedocs.org/en/latest/tutorials/Django_and_nginx.html#using-unix-sockets-instead-of-ports. Я работаю с Ubuntu 14.4 например, на Amazon EC2:

Конфигурационный файл Nginx начинается с:

# 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) 
} 

Я смущен о синтаксисе создания сокета UNIX. Я посмотрел на несколько источниках, включая http://pymotw.com/2/socket/uds.html, Permission denied - nginx and uwsgi socket и https://serverfault.com/questions/124517/whats-the-difference-between-unix-socket-and-tcp-ip-socket

Это выглядит как все они начинаются с «///» Если я правильно понял путь только указует на корневом каталог (в моем случае) Джанго проект и путь должен заканчиваться на «.sock». Кажется ли это правильным?

редактировать: Я сделал конфигурационный файл uwsgi, но я пытаюсь запустить это с --socket переключателем вместо:

Конфигурационный файл Nginx теперь начинается с:

# 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) 
} 

После того, что я думаю, вы говорите, я запускаю uwsgi на socket /tmp/mysite.sock.

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

Когда я открываю:

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

В светлячок я вижу:

502 Bad Gateway 

Журнал ошибок для Nginx показывает:

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" 

редактировать 2: Я закомментирована связанные с django вещи -

# 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 

Я пробовал:

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

но снова получил ошибку 502.

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

Так каждый раз, когда я выхожу uWSGI, сокет удаляется. Может быть, мне нужно отключить параметр вакцины, чтобы сохранить настройки chmod?

Я изменил:

vacuum   = false 

но ...

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

Теперь получаю внутренняя ошибка сервера:

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

Изменить это сказать сервер unix:///tmp/mysite.sock;, а затем в uwsgi ини файл, который вы делаете, создать сокет Unix в /tmp/
