连接被拒绝django-gunicorn nginx

Question

在我的网站上运行搜索功能时，我收到以下错误(搜索功能向我的api服务器发出api请求(：

2022/08/31 21:01:56 [error] 726#726: *23 connect() failed (111: Connection refused) while connecting to upstream, client: 11.111.111.111, server: api.mydomain.com, request: "GET /dividends/IBM/3/5 HTTP/1.1", upstream: "http://127.0.0.1:8001/dividends/IBM/3/5", host: "api.example.com", referrer: "example.com/"

监管程序gunicorn启动，mongodb启动，nginx启动

我有以下/etc/nginx/sites-available/stocks_backend:

upstream stocks_backend {
server 127.0.0.1:8001 fail_timeout=4s;
}
server {
server_name api.example.com www.api.example.com;
location = /favicon.ico { access_log off; log_not_found off; }
location /static/ {
root /root/stocks_backend;
}
location / {
include proxy_params;
proxy_pass http://unix:/etc/systemd/system/gunicorn.socket;
proxy_ssl_server_name on;
}

}
server {
if ($host = api.example.com) {
return 301 https://$host$request_uri;
} # managed by Certbot

listen 80;
listen [::]:80;
server_name api.example.com www.api.example.com;
return 404; # managed by Certbot
access_log /root/stocks_backend/log/nginx-access.log;
error_log /root/stocks_backend/log/nginx-error.log;
}

我在连接到上游时尝试过Django gunicorn nginx(111:连接被拒绝(的东西，但当我从proxy_pass中删除http://到proxy_pass unix:/etc/systemd/system/gunicorn.socket;的套接字时，我得到了

nano /etc/nginx/sites-available/stocks_backend
root@my-droplet:~/stocks_backend# sudo service nginx restart
Job for nginx.service failed because the control process exited with error code.
See "systemctl status nginx.service" and "journalctl -xe" for details.

gunicorn插座

root@-droplet:~/stocks_backend# cat /etc/systemd/system/gunicorn.socket 
[Unit]
Description=gunicorn socket
[Socket]
ListenStream=/run/gunicorn.sock
[Install]
WantedBy=sockets.target

更改此行

proxy_pass http://unix:/etc/systemd/system/gunicorn.socket;

至

proxy_pass unix:/etc/systemd/system/gunicorn.socket;

本质上删除http://，因为NGINX与Gunicorn的通信方式并非如此。

那么，对于OP遇到的另一个问题，到目前为止，OP还没有足够的细节。

OP如何获得有关该问题的更多详细信息？OP可以设置NGINX错误日志，如下所述。然后OP应该能够使用日志中的信息来解决问题。
