У меня возникают проблемы при настройке сервера с использованием UWSGI и NGINX. Это мой UWSGI INI-файл (и символическая ссылка в вассалах):

# ebook_uwsgi.ini file
[uwsgi]
#emperor = /etc/uwsgi/vassals
#plugins        = python #if uwsgi installed with pip, dont have to use this line
# Django-related settings
# the base directory (full path)
chdir           = /var/www/django/ebook/ebook/wsgi/ebook/
# Django's wsgi file
module          = controller.wsgi:application
# the virtualenv (full path)
home            = /var/www/django/ebook

# process-related settings
# master
master          = true
# maximum number of worker processes
processes       = 10

# the socket (use the full path to be safe
socket         = /var/uwsgi/ebook.sock
# ... with appropriate permissions - may be needed
chmod-socket    = 664
uid             = www-data
gid             = www-data
# clear environment on exit
vacuum          = true


no-site         = True
wsgi-file       = /var/www/django/ebook/ebook/wsgi/ebook/controller/wsgi.py
#env             = DJANGO_SETTINGS_MODULE=controller.settings # set an environment variable

и это мой файл конфигурации nginx:

# mysite_nginx.conf

# the upstream component nginx needs to connect to
upstream django {
    server unix:///var/uwsgi/ebook.sock; # for a file socket
    #server 127.0.0.1:8000; # for a web port socket (we'll use this first)
}

# configuration of the server
server {
    # the port your site will be served on
    listen      8000;
    # the domain name it will serve for
    server_name IP; #www.domain.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 /var/www/django/ebook/ebook/data;  # your Django project's media files - amend as required
    }

    location /static {
        alias /var/www/django/ebook/ebook/wsgi/static/; # your Django project's static files - amend as required
    }

    # Finally, send all non-media requests to the Django server.
    location / {
        include     /var/www/django/ebook/ebook/uwsgi_params; # the uwsgi_params file you installed
    }
}

Когда я запускаю uwsgi как мой пользователь (lucas03)

uwsgi --emperor /etc/uwsgi/vassals --uid www-data --gid www-data

это вывод:

ebook.sock создан:

drwxrwxr-x  2 www-data www-data  3 máj 12 20:43 .
drwxr-xr-x 13 root     root     15 apr 14 16:29 ..
srw-rw-r--  1 lucas03  lucas03   0 máj 12 20:43 ebook.sock

но я получаю502 Bad Gateway, Поэтому я меняю владельца ebook.sock на www-datasudo chown www-data:www-data ebook.sockмой сайт загружен правильно. Ну, я думал, что это было здорово. Теперь мне просто нужно запустить uwsgi, чтобы он мог создавать ebook.sock в качестве пользовательских www-данных.
Итак, я установилuwsgi для запуска при запускеЯ редактировал/etc/rc.local.

#!/bin/sh -e
#
# rc.local
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "exit 0" on success or any other
# value on error.
#
# In order to enable or disable this script just change the execution
# bits.
#
# By default this script does nothing.
/usr/local/bin/uwsgi --emperor /etc/uwsgi/vassals --uid www-data --gid www-data
exit 0

Однако после перезапуска сервера файл ebook.sock вообще не создается, хотя uwsgi запускается. (Я вижу это вps aux | grep uwsgi). Поэтому я подумал, что он запускается таким же или похожим образом, как если бы я запускал этот файл как root.
Итак, я запускаю файл/etc/rc.local и это вывод:

Поскольку вывод короче, я думаю, файлы конфигурации в/etc/uwsgi/vassals не загружены, и есть некоторые проблемы с управлением вассалами императора.
У кого-нибудь есть идеи, почему? Заранее спасибо за любой ответ или комментарии.
