我在使用uwsgi和nginx设置服务器时遇到问题。这是我的uwsgi ini文件（和附庸中的符号链接）：
# 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
这是我的nginx conf文件：
# 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
}
}
当我以用户身份运行uwsgi时（lucas03）
uwsgi --emperor /etc/uwsgi/vassals --uid www-data --gid www-data
这是输出：

ebook.sock已创建：

drwxr-xr-x 13 root root 15 apr 14 16:29 ..
srw-rw-r-- 1 lucas03 lucas03 0 máj 12 20:43 ebook.sock
但我得到502 Bad Gateway。所以我将ebook.sock的所有者更改为www-data sudo chown www-data:www-data ebook.sock，我的网站正确加载。好吧，我觉得这很棒。现在我只需要运行uwsgi就可以创建ebook.sock作为用户www-data
所以我设置了uwsgi to start on startup，我编辑了/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
然而，在我重启服务器之后，虽然uwsgi运行，但根本没有创建ebook.sock文件。 （我可以在ps aux | grep uwsgi中看到它）。所以我认为它运行方式与我以root身份运行该文件的方式相同或类似
所以我运行文件/etc/rc.local，这是输出：

由于输出较短，我想/etc/uwsgi/vassals中的配置文件未加载，并且运行皇帝附庸存在一些问题。
有谁知道为什么？提前感谢您的任何回答或评论。
答案 0 :(得分：4)
将/var/www/django/的所有者更改为www-data使其正常工作。
具体问题是文件/etc/nginx/uwsgi_params的所有权。

更改sock文件夹的文件权限...
