Airflow + Nginx set up gives Airflow 404 = lots of circles

问题

I'm trying to set up Airflow behind nginx, using the instructions given here.

airflow.cfg file

base_url = https://myorg.com/airflow
web_server_port = 8081
.
.
.
enable_proxy_fix = True

nginx configuration

server {
    listen 443 ssl http2 default_server;
    server_name myorg.com;
    .
    .
    .
    location /airflow {
        proxy_pass http://localhost:8081;
        proxy_set_header Host $host;
        proxy_redirect off;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
        proxy_set_header X-Forwarded-Proto "https";
    }
}

Airflow webserver and scheduler are up and running as systemd. When I try to access https://myorg.com/airflow/, it gives Airflow 404 = lots of circles.

What could be wrong? Really appreciate your help in getting this running.

回答1:

I just had the same problem and fixed it by adding a tailing / to the location: location /airflow/ { instead of location /airflow {. The tailing backslash tells nginx to remove the preceeding /airflow in uri paths to the corresponding python app.

My overall config looks as follows:

    server_name my_server.my_org.net;
    location /airflow/ {
        proxy_pass http://localhost:9997;
        proxy_set_header Host $host;
        proxy_redirect off;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
    }

In airflow.cfg I additionally specified:

base_url = http://my_server.my_org.net/airflow
enable_proxy_fix = False  # Seems to be deprecated?
web_server_port = 9997

I run into the same problem using https.
But using the configuration in the solution led me to another problem.

Anything other than /airflow/ location falls back to / location. Returning 404 errors to assets.

Using the configuration bellow solved the issue:

location ^~ /airflow/ {
  proxy_pass_header Authorization;
  proxy_pass http://localhost:8080/airflow/;
  proxy_set_header Host $host;
  proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
  proxy_set_header X-Forwarded-Host $host:$server_port;
  proxy_set_header X-Forwarded-Server $host;
  proxy_set_header X-Forwarded-Proto $scheme;
  proxy_set_header X-Real-IP $remote_addr;
  proxy_http_version 1.1;
  proxy_redirect off;
  proxy_set_header Connection "";
  proxy_buffering off;
  client_max_body_size 0;
  proxy_read_timeout 36000s;
}
