django、gunicorn和Nginx的502错误

几天来，我一直在尝试将django设置为与nginx和gunicorn合作，遵循设置指南，尝试在此论坛中找到的许多解决方案，但没有一个对我有效

这是我的第一篇stackoverflow文章，如果它的格式错误或者写得不好，根据你喜欢的阅读方式，我希望听到它，以便我可以改进

从文件夹中启动gunicorn

/home/django/virtualenv/sio/SiO

运行命令

gunicorn --bind 0.0.0.0:8000 SiO.wsgi:application

工作很好，我试着将它设置为sock文件夹。但我最近尝试的是wsgi.py文件所在的/home/django/virtualenv/sio/sio/sio

当查看nginx错误日志时，我发现

我的gunicorn文件位于

/home/django/virtualenv/sio/bin/gunicorn

/etc/systemd/system/gunicorn.service的内容

[Unit]
Description=gunicorn daemon
After=network.target

[Service]
User=django
Group=www-data
WorkingDirectory=/home/django/virtualenv/sio/SiO
ExecStart=/home/django/virtualenv/sio/bin/gunicorn --workers 3 --bind unix:/home/django/virtualenv/sio/SiO/SiO SiO.wsgi:application

[Install]
WantedBy=multi-user.target

和my/etc/nginx/sites available/sio文件

server {
    listen 80;
    server_name 67.207.75.163;

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

    location / {
        include proxy_params;
        proxy_pass http://unix:/home/django/virtualenv/sio/SiO/SiO.sock;
    }
}

当试图仅使用django构建的inn Web服务器运行时，该站点可以正常工作。当尝试使用gunicorn访问时，我得到一个502错误

这行中缺少“.sock”：

ExecStart=/home/django/virtualenv/sio/bin/gunicorn--workers 3--bind unix:/home/django/virtualenv/sio/sio/sio.wsgi:application

您绑定到的是一个文件夹而不是一个sock文件，但您告诉nginx查找/home/django/virtualenv/sio/sio/sio.sock

因此，不妨尝试一下：

ExecStart=/home/django/virtualenv/sio/bin/gunicorn--workers 3--bind unix:/home/django/virtualenv/sio/sio/sio.sock sio.wsgi:application

编辑：顺便说一句，我是这个设置的忠实粉丝，对它的推荐也不够高-

进行您建议的更改并没有解决问题，尝试您在新VM中发送的指南是否解决了所有问题。非常感谢。这真是太棒了，通常数字海洋指南是我的目标，但你说服了我去其他地方看看：）

nginx和gunicorn作为不同的用户运行。nginx是否可以读取/home/django？如果unix套接字有问题，为什么不使用tcp/ip，直到解决这个问题？
