Django部署Gunicorn和NginX

Question

尝试最终部署我的新流动站Web应用程序时，出现了问题。 我已经配置了Gunicorn并将其绑定到0.0.0.0:80（使用wsgi）。 网站已加载，但没有任何图像，C​​SS，JavaScript文件（即使“ admin”网站也没有任何样式）。 Postgres已安装并运行良好。 我已经做了

python manage.py collectstatic
python manage.py migrate

我看了很多教程如何做到这一点。 但仍然在我尝试运行后：

systemctl status nginx.service

我得到一个错误：

Job for nginx.service failed because the control process exited with error code. 
See "systemctl status nginx.service" and "journalctl -xe" for details.


#systemctl status nginx.service output:

以及网站中可用的“流动站”文件（与项目名称相同）（我已经将其链接到启用了网站的文件）：

server {
    listen 80;
    server_name :333 ;

    location = /favicon.ico { access_log off; log_not_found off; }
    location /static/ {
        root /home/.../website/rover/rover;
    }

    location / {
        include proxy_params;
        proxy_pass http://unix:/run/gunicorn.sock;
    }
}

gunicorn.sock存在于/ run /目录中。...有什么建议吗？

Answer 1

nginx告诉您，它无法绑定到端口80，因为某些其他进程已经在侦听该端口。 您可以在此处的日志输出中看到此内容：

nginx [5957]：nginx：[emerg] bind（）到0.0.0.0:80失败（98：地址已在使用中）

要检查哪个进程正在此端口上监听，可以使用netstat或更好的ss ：

~# ss -naptu state listening | grep :80
tcp   0      128       0.0.0.0:80                    0.0.0.0:*                   users:(("nginx",pid=6824,fd=4),("nginx",pid=6823,fd=4))

~# netstat -tulpen | grep :80
tcp        0      0 0.0.0.0:80              0.0.0.0:*               LISTEN      0          136280382  6823/nginx: master

最后一列将显示进程名称和在端口上侦听的进程的pid。
