【问题描述】：

我是 Python Django 的新手，我已经成功创建了我的应用程序，当我尝试在 Ubuntu 16.04 上托管我的 Django 应用程序时，它无法正常工作我尝试了多种方法并用谷歌搜索了很多，请帮助摆脱这种情况。

我关注了这个 URL How To Set Up Django with Postgres, nginx, and Gunicorn on Ubuntu 我已经正确完成了所有设置，但我仍然没有成功。在这里，我分享必要的文件供您参考，如果我错过了什么，请告诉我。

etc/nginx/site-available

server 
    listen *:91;
    server_name ip-address;
    location = /favicon.ico  access_log off; log_not_found off; 
    location /static/ 
            root /home/iradmin/django/scm;
    
    location / 
            include proxy_params;
            proxy_pass http://unix:/home/iradmin/django/scm/scm.sock;
    

etc/inint/gunicorn.confi

decription "Gunicorn application server handling scm"
start on runlevel [2345]
stop on runlevel [!2345]
respawn
setuid iradmin
setgid www-data
chdir /home/iradmin/django/scm/
exec python3venv/bin/gunicorn --workers 3 --bind unix:/home/iradmin/django/scm/scm.sock scm.wsgi:application

当我完成所有部署步骤后，我在 nginx/error.log 中遇到以下错误

2018/06/25 18:59:50 [crit] 32640#32640: *8 connect() to unix:/home/iradmin/django/scm/scm.sock failed (2: No such file or directory) while connecting to upstream, client: 10.200.101.124, server: ip-address, request: "GET / HTTP/1.1", upstream: "http://unix:/home/iradmin/django/scm/scm.sock:/", host: "10.200.101.227:91"

这是我的应用程序结构

独角兽状态

root@iradmin-OptiPlex-3040:/etc/init# sudo service gunicorn status
● gunicorn.service - gunicorn daemon
   Loaded: loaded (/etc/systemd/system/gunicorn.service; enabled; vendor preset: enabled)

我尝试了几种方法，但我仍然不知道 .sock 文件以及如何创建它？非常感谢您的回复。

【参考方案1】：

文件“.sock”将通过适当的配置自动创建。无需手动创建。在 etc/inint/gunicorn.confi 文件中给出 gunicorn 的绝对值

exec python3venv/bin/gunicorn

应该是

exec /path/.../python3venv/bin/gunicorn
