Question

我试图在Linode上的虚拟Ubuntu 14.04盒子上设置我的Mezzanine / Django项目，但是得到了一个＆＃34; 502 Bad Gateway错误＆＃34;尝试在浏览器中导航到我的网站时。

我按照此处的说明操作：https://linode.com/docs/web-servers/nginx/deploy-django-applications-using-uwsgi-and-nginx-on-ubuntu-14-04。

我在git clone中运行了/home/django/，因此所有内容都位于名为FOLDER的文件夹中。

/home/django/包含以下目录：Env/和FOLDER/。

这应该让我们了解FOLDER/树的样子：

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

在我的settings.py中，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......

/var/log/nginx/error.log有此信息（已删除识别信息）：

似乎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框的地址并查看工作网站？

Answer 1

套接字文件应该由uWSGI创建。但是uWSGI日志告诉你它无法启动，因为它无法cd到你在product_blog.ini，/home/django/product_blog中指定的目录。

我无法判断FOLDER是否是占位符，但无论如何您似乎并未将其包含在该路径中。我想它应该是：

chdir = %(base)/FOLDER/%(project)
...
socket = %(base)/FOLDER/%(project)/%(project).sock

＆＃34; .sock＆＃34;不存在错误; connect（）错误
