Django: How can I access celery flower page in production mode?

Question

In development mode(local), it is really easy to access flower page (http://localhost:5555)

But in production mode, it is difficult to access flower page.

I'd like to access flower dashboard page with this url:
https://spacegraphy.choislaw.xyz/flower/ (Domain name : choislaw.xyz)

I refered http://flower.readthedocs.io/en/latest/reverse-proxy.html#reverse-proxy and this is what I did:

nginx.conf

  http {
      include       mime.types;
      default_type  application/octet-stream;
      sendfile        on;

      server {
          listen       80;
          server_name  spacegraphy.choislaw.xyz;

          client_max_body_size 4G;
          keepalive_timeout 5;

          return 301 https://$server_name$request_uri;
      }


      # HTTPS server
      server {
          listen       443 default_server ssl;
          server_name  spacegraphy.choislaw.xyz;

          client_max_body_size 4G;
          keepalive_timeout 5;

          ssl_certificate      /etc/letsencrypt/live/spacegraphy.choislaw.xyz/fullchain.pem;
          ssl_certificate_key  /etc/letsencrypt/live/spacegraphy.choislaw.xyz/privkey.pem;

          location / {
              proxy_pass_header X-CSRFToken;
              proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
              proxy_set_header X-Forwarded-Proto https;
              proxy_set_header X-Real-IP $remote_addr;
              proxy_set_header HOST $http_host;
              proxy_set_header X-NginX-Proxy true;

              proxy_pass http://127.0.0.1:4349;
              proxy_redirect off;
          }

          # Flower
          location /flower/ {
              proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
              proxy_set_header X-Forwarded-Proto https;
              proxy_set_header X-Real-IP $remote_addr;
              proxy_set_header HOST $http_host;
              proxy_set_header Upgrade $http_upgrade;
              proxy_set_header Connection "upgrade";
              proxy_http_version 1.1;

             proxy_pass http://localhost:5555/;
             proxy_redirect off;
         }
     }
 }

And I execute flower server:

$ celery --workdir=spacegraphy/  --app=spacegraphy.celery:app flower

And I access https://spacegraphy.choislaw.xyz/flower/, it shows like this:

And If I click any link,

Did I miss something? Do I separate flower server from application server?

Btw, Is it usual to run flower server on production server?

Is it usual to run flower server on production server? For me, only enable it for maintenance purpose. — kkiat, Dec 21 '16 at 04:03
@Jinje How can I set settings file for static files for flower? — user3595632, Dec 21 '16 at 05:37
may refer to example here: [link](https://github.com/mher/flower/blob/master/examples/nginx.conf) — kkiat, Dec 21 '16 at 06:30
@Jinje static files might be located in my virtual environment's site-package/flower something. Is it the `/path/to/flower/static` ? — user3595632, Dec 21 '16 at 07:33
yes, path of the static folder of flower in the virtual environment package — kkiat, Dec 21 '16 at 07:34

you need change flower nginx conf to:

location ~ ^/flower/? {
    rewrite ^/flower/?(.*)$ /$1 break;

    sub_filter '="/' '="/flower/';
    sub_filter_last_modified on;
    sub_filter_once off;

    # proxy_pass http://unix:/tmp/flower.sock:/;
    proxy_pass http://localhost:5555;
    proxy_redirect off;
    proxy_set_header Host $host;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "upgrade";
    proxy_http_version 1.1;
}

Actually you'll need both previous solutions at the same time:

Run flower with --url-prefix=flower as @osmay88 mentioned

Configure Nginx location section in next manner:

location ~ ^/flower/? {
    proxy_pass http://<IP>:<PORT>;
    rewrite ^/flower/?(.*)$ /$1 break;
}

When in use without url-prefix but with sub_filter then this will cause "Monitor" page to be empty.

@Vladimir Sh. I'm trying to use flower in production too, however my flower doesn't have real time response. do you know how to configure the nginx for real time monitoring? – luvwinnie Jan 04 '20 at 09:46
@luvwinnie If I understand you correctly, there's a flag "celery flower --auto_refresh=True" – iChux Nov 03 '22 at 08:48

Quick clarification: (I believe API might've changed) current docs indicate that this option should use an underscore (i.e. `flower --url_prefix=flower`) rather than a hyphen; source: https://flower.readthedocs.io/en/latest/config.html#url-prefix – lgants Jan 03 '21 at 20:48

from doc

$ flower --url_prefix=flower

nginx.conf

location /flower/ {
    rewrite ^/flower/(.*)$ /$1 break;
    proxy_pass http://example.com:5555;
    proxy_set_header Host $host;
}
