“.sock”不存在错误；connect() 错误

我正在尝试在 Linode 上的虚拟 Ubuntu 14.04 盒上设置我的 Mezzanine/Django 项目，但是当我尝试在浏览器中导航到我的网站时出现“502 Bad Gateway 错误”。

我按照这里的说明进行操作：https://linode.com/docs/web-servers/nginx/deploy-django-applications-using-uwsgi-and-nginx-on-ubuntu-14-04。

我跑git clone进去了/home/django/，所以所有内容都在名为的文件夹中FOLDER。

/home/django/有以下目录：Env/和FOLDER/。

这应该能让你大致了解FOLDER/树的样子：

FOLDER
- product_blog
-- product_blog
--- settings.py
--- wsgi.py
-- manage.py

在我的 中settings.py，我有：

ALLOWED_HOSTS = ["PUBLIC IP OF MY LINODE UBUNTU INSTANCE HERE"]

wsgi.py有这个：

"""
WSGI config for product_blog project.

It exposes the WSGI callable as a module-level variable named ``application``.

For more information on this file, see
https://docs.djangoproject.com/en/1.10/howto/deployment/wsgi/
"""

import os

from django.core.wsgi import get_wsgi_application
from mezzanine.utils.conf import real_project_name

os.environ.setdefault("DJANGO_SETTINGS_MODULE",
                      "%s.settings" % real_project_name("product_blog"))

application = get_wsgi_application()

/etc/uwsgi/sites/product_blog.ini有这个：

[uwsgi]
project = product_blog
base = /home/django

chdir = %(base)/%(project)
home = %(base)/Env/%(project)
module = %(project).wsgi:application

master = true
processes = 2

socket = %(base)/%(project)/%(project).sock
chmod-socket = 664
vacuum = true

/etc/init/uwsgi.conf有这个：

description "uWSGI"
start on runlevel [2345]
stop on runlevel [06]
respawn

env UWSGI=/usr/local/bin/uwsgi
env LOGTO=/var/log/uwsgi.log

exec $UWSGI --master --emperor /etc/uwsgi/sites --die-on-term --uid django --gid www-data --logto $LOGTO

/etc/nginx/sites-available/product_blog有这个：

server {
    listen 80;
    server_name mydomain.com;

    location = /favicon.ico { access_log off; log_not_found off; }
    location /static/ {
        root /home/django/FOLDER;
    }

    location / {
        include         uwsgi_params;
        uwsgi_pass      unix:/home/django/FOLDER/product_blog/product_blog.sock;
    }
}

当我转到 Linode 框的 IP 地址时，我看到 502 Bad Gateway 错误。

/var/log/uwsgi.log有这个...

还有/var/log/nginx/error.log这个（删除了识别信息）：

2018/04/22 17:18:14 [crit] 3953#0: *9 connect() to unix:/home/django/FOLDER/product_blog/product_blog.sock failed (2: No such file or directory) while connecting to upstream, client: 73.49.35.42, server: mydomain.com, request: "GET / HTTP/1.1", upstream: "uwsgi://unix:/home/django/FOLDER/product_blog/product_blog.sock:", host: "ADDRESS TO LINODE BOX"

看起来它product_blog.sock应该在我的目录中的某个地方，但它不在那里。如何修复 502 错误，以便我可以将浏览器导航到 Linode 框的地址并查看正常运行的网站？
